All the knowledge contained in the Holy Grail of how vehicles handle had just become mine. And any technically minded general-interest reader will find here an utterly scientific exposition of why wheeled vehicles comport themselves the way they do, and even the lay person possessed of some measure of curiosity will come to appreciate just how staggeringly complex vehicle dynamics are and will never again take a smooth ride for granted! PAE includes many open-ended problems, such as suggestions for experiments that require your very own car. The CD, incidentally, is based on material Dr.

Milliken ID: Review We offer no apologies for making this important… book our choice for the second time around. Widely welcomed, its content is already beingput to good use by many race car engineers… Today, anyone who wishes to make a career by understanding the automobile and its vagaries should start here.
Very highly recommended. If you were missing deep theoretical background on tuning your sports car or street car, this volume is for you. It is impossible to describe in detail what this textbook is about, in a single review. What I liked most is the chapter on dampers shock absorbers. Why stiffer dampers are more comfortable on large-amplitude bumps, while softer dampers provide smoother ride on small-amplitude bumps?
As measure of discomfort is the vertical acceleration that the passenger is subjected while sitting in the vehicle". The book demonstrates the model where the passenger is linked to the road via three springs in a sequence: tire, coil and the seat, and one damper shock absorber. There is a graph showing passenger vertical acceleration depending on the amplitude frequency of road irregularities, for distinct shock absorbers with various damping ratios.
For a stiff shock absorber this diagram shows relatively flat curve, where the vertical acceleration is almost independent of frequency of bumps. For the soft shock absorber, there is a very high peak several times higher comparing to a stiff damper of vertical acceleration for the low-frequency bumps, and this acceleration curve quickly decays as the frequency increases.
There is another graph, "transient load transfer analysis", which shows that with soft dampers, the suspension load in a turn fluctuates.
