Development and Simulation of 39 DOF Vehicle Model

In this study, a 39 degree-of-freedom mass-spring-damper model of vehicle was developed. The consists 4 parts: wheels and suspensions, body, seats passengers. A human with 7 degrees freedom used to the Equations motion were obtained by drawing free body diagram each part. order solve equations numerically, created in Simulink environment. To verify accuracy outputs from model, script written using Python programming language. developed tested applying road profile. Outputs test are agreement other literature. Thanks situations that affect passenger driving comfort during design will be examined detail less experimentation.
