Analytical and Experimental Studies of Vehicle Dynamics Behavior


Carlson, John Arthur (1955) Analytical and Experimental Studies of Vehicle Dynamics Behavior. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/4TY3-Y818.


This thesis represents one step in the development of analysis in the field of vehicle dynamics made possible by modern computational techniques. A research program was set up, the main object of which was to conduct an appraisal of analysis by comparing the results of analysis with actual vehicle tests. Both experiment and theory are included in this one investigation. The following general conclusions were drawn from the results of the research program: 1. Relatively simple systems giving good quantitative results can be used to represent a vehicle in motion over a variety of courses. 2. The effects of varying vehicle properties (spring rates, damping characteristics, masses) can be studied by using these simple systems. The results obtained are of sufficient accuracy to be used for design purposes. An example of a design study demonstrating the application of analysis to a specific problem is presented. The problem was to investigate the possible use of the engine as a dynamic vibration absorber. The conclusion reached is that the engine mount stiffness may be chosen such that the shake of the frame caused by wheel bounce may be reduced. Conclusions reached on the effects of some automobile properties (suspension bump stops, suspension damping, and tire damping) are summarized.
