Optimization of the suspension damper on a quarter car model using ride comfort criteria in a multiobjective function

摘要

After theoretical background for the ride comfort and driving safety optimization, a study of the influence of the ride comfort criteria to a multiobjective optimization of a suspension damper is presented in this paper. The objective function Obj_(SCD) was constructed as a weighted combination of the ride comfort perception quantity a_(vT), standard deviation σ_(Fn) of the normal tire force, and standard deviation σ_D of the relative displacement of the wheel to the car body. For the ride comfort perception optimization and the car model identification a MATLAB toolbox was developed.
