ABOUT THE AUTHOR H erb Adams began his automotive engineering career when he joined the engineering staff at Pontiac after graduating from the General Motors Institute in At Pontiac, he designed and developed a variety of experimental and production engines, most notably the Pontiac Trans Am. Inhe left General Motors to begin his own automotive engineering and consulting business, while building his own racing cars which he drove in several professional racing series, includ ing the SCCA Trans-Am.
His company, VSE, specializes in handling and appearance items for American sports cars, such as the Camaro, Firebird, Corvette and Mustang. He also serves as an engineering consultant to Goodyear, Pontiac, Oldsmobile, Koni, Appliance Wheels and Cincinnati Microwave.
In recent years, he has written numerous articles on chassis design and building for Circle Track magazine. He lives in Northern California. One area of race car performance that still seems difficult to explain is suspension and handling. Although many enthusiasts can tell you what changes will produce what results, they may not be able to tell you why these changes produce these results. In order to understand the whys of suspension and han dling, you need to study the physics involved.
Since not all enthusiasts have an engineering or physics background, this book will attempt to discuss suspensions and handling in terms the layperson can understand. Good handling could be described as going around corners faster while improving driver control. Suspensions are involved in the han dling equation because they control how the tires work against the track.
Because the tires are the only link between the car and vi the track, they are the key to improved han dling. Almost all of the suspension variables are related to how well a car's tires react to the ground. Just as in the case of engine tuning, where very small changes can have a dramatic effect on horsepower output, very slight changes in the suspension of your car can have significant effects on your handling, chassis engineering herb adams pdf download. Even a one-degree change in camber can have a measurable effect on performance, chassis engineering herb adams pdf download, so a high degree of precision is required to set-up a suspension properly.
Another aspect of suspension tuning that should be stressed at the beginning is the con cept of optimizing settings. For example, if you increased your tire pressure from 30 to 40 psi, and you measured some improvement, there is no reason to assume that increasing the pres sure from 40 to 50 psi will have an equal improvement.
If the tire operates best at 40 psi, increasing the pressure to 50 psi could actually reduce its performance. Every suspension adjustment and setting has an optimum value. We know that more valve timing in an engine can increase power up to a certain point and then further increases will lose chassis engineering herb adams pdf download. The same concept is true in suspension tuning.
This is not an engineering book in the classi cal sense, chassis engineering herb adams pdf download, but rather an explanation of how engi neering principles are applied to the automobile chassis. This application of engineering to the automobile chassis engineering herb adams pdf download is a very specialized field of study, so it is not widely practiced.
However, the interest in chassis engineering is very broad, because there are so many automotive enthusiasts interested in improving the corner ing performance of their cars. By studying the engineering relationships, chassis engineering herb adams pdf download, and the examples given in this book, most enthusiasts with aver age mechanical skills should be able to make significant improvements in the cornering per formance of their car, regardless of the type or application, be it street, circle track or road rac ing.
Because of the many different types of vehi cles and racing applications, it would be nearly impossible to do a true "how-to" book. The chassis engineering herb adams pdf download is to present chassis engineering herb adams pdf download information in a universal man ner, so it can be applied to suit chassis engineering herb adams pdf download need.
The information contained in this book was accumulated over many years, the result of numerous contributions by top engineers and racers. It is not unusual for an engineer or a car builder to struggle for months to solve a prob lem.
And, once they do find the answer, chassis engineering herb adams pdf download, it is sim ple to follow their lead. During the past 30 years, there has been a tremendous increase in the available knowledge on car handling, and this book attempts to present some of this infor mation. Therefore, when "we" is used through out this book, it refers to all those people who have helped to accumulate this information.
To help explain the handling concepts, I have organized this book using the "building block" approach.
The first chapters present the most basic concepts. The later chapters use these basic concepts to explain the more complicated relationships and solve common problems. Don't read the chapters out of order, because you need to fully understand tire characteris tics before you can understand weight distribu tion dynamics, or you need to know how tire loadings, stabilizer chassis engineering herb adams pdf download and spring rates affect handling before you can correct any oversteer or understeer problems.
The study of chassis engineering is complex and can be difficult to grasp. Hopefully, this book will make it easier. Understanding how the tires work on your car is absolutely necessary in order to understand why a car handles the way it does, or more importantly, to change how it handles. To sim plify the study of how tires work, we can limit the analysis to their input-output characteristics, since these are the most important factors that affect han dling.
This type of analysis is called the black-box methodbecause we do not concern ourselves with what is going on inside the "box," or tire in this case. Vertical Load-The input for tire performance is the vertical load, or weight, on the tire. The dynamics of the car in motion cause this load to vary continu ously. By tuning the chassts, it is possible to adjust how this vertical tire loading will change, and by knowing how the tire will respond to the change in loading, you will be able to predict the effect of the changes.
Traction-The output of a tire from a handling standpoint is its traction or how well it "sticks" to the ground. TIRE TRACTION VS. LOAD It is necessary to know how the tire translates the input into output to understand how a car will han dle the way it does.
In other words, you need to know how changes in vertical load input affect the traction output. The relationship between tire input and output forces is different for every tire but, more importantly, the relationship changes dra matically as the vertical loading is changed. This changing relationship is the major reason why the study of handling is often confusing.
Although the relationship between vertical load and traction for any given tire is continually chang ing, the interaction between the two will follow a curve similar to that shown in Figure It is not necessary to have the tire performance curve for your specific tires because we are looking for the tire characteristics, not the exact values.
The shape of the tire performance curve is what is important. Different tires will have performance curves with different shapes or values, but they all will have a curve that results in a smaller increase in traction as the vertical load is increased.
Wecall this loss of rel ative traction a loss in the tire's cornering efficiency. Good handling depends on optimiz ing how your car uses its tires.
You need to know what your tires chassis engineering herb adams pdf download if you expect to maxi mize their performance. J 1, Figure This is a tire performance curve. The amount attraction By making a chart of the tire performance curve Chart it is possible to see how the cornering efficiency of the tire decreases as the vertical load ing is increased.
The vertical load and traction read ings were taken from the tire performance curve Figure Efficiency is output traction divided by input vertical load as shown on Chart Bylooking at tire cornering efficiency, you can eas ily see that you will get the most cornering power as a percentage of the vertical load when the vertical loads are lower.
Atire's cornering efficiency reduces quickly when it is asked to support more and more weight. This characteristic of any tire is a key ele ment in understanding why cars handle the way they do. Understanding this aspect of a tire's per formance is necessary to analyze the more complex conditions that a car experiences during actual driv ing conditions.
available from any given tire is dependent on how much weight is on the tire. As weight is increased, the traction also increases. The important thing that must be recognized however, is that the increase in traction becomes less and less as the weight is increased. Vertical Load Chart VERTICAL LOAD V5. TIRE PATCH ZERO CAMBER POSITIVE CAMBER V" ~ tI I- v ~ '-- ~ TIRE PATCHES Figure When a tire is perpendicular to the ground, it has zero camber angle. This condit ion provides the biggest tire patch for the most possibl e tracti on.
Equally important is that the unit -loading on each part of the tire pat ch is more evenly distributed when the tire has zero camber angle. As shown here, a positive camber angle will result in less of a tire patch. CIRCLE OF TRACTION Tire Factors-When analyzing your car's handling, tire factors such as contact patch, tread depth, aspect ratio, etc. These factors raise or lower the traction curve and they can cause the shape of the curve to change.
When the same size and type of tire is used at all four locations, these factors affect how much traction is available. This is called zero camber angle Figure When the tire is perpendicular to the ground, its con tact patch is bigger than when it is at any other angle.
Contact patch is the area of the Ute in direct contact with the road surface. If a tire is tilted out at the top, it has positive camber. This condition reduces the tire contact patch and the tire will not provide as much traction as when it is perpendicular. Negative camber, chassis engineering herb adams pdf download, when the top of the tire is tilted inward, is often dialed in to compensate for the moving or bending known as chassis engineering herb adams pdf download of suspension parts.
When it is used, the result is to have zero camber angle when maximum tire traction is needed.
