Analysis of Vehicle Chassis Transmissibility of Steering Shimmy and Brake Judder: Mechanism Study and Virtual Design of Experiment 2007-01-2342
The simulation model developed and validated by the authors  for vehicle chassis transmissibility of steering shimmy and brake judder is used to analyze the transmissibility mechanism and quantify the relative importance of system factors, through modal analysis around equilibrium point and a virtual DOE (design of experiment) process. Contributing chassis vibration modes are discovered, relative importance of chassis factors is efficiently determined, and potential areas for improving chassis shimmy/judder sensitivity are identified. The DOE results are further confirmed by the comparison of simulated and on-road measured shimmy/judder change with the specification change of key factors. Also presented is some successful application of the simulation technology and analysis results to vehicle development.
