- Summary:
- The characteristics of suspension elastic elements (id est,spring, damper and anti-roll bar) are directly related to thehandling and ride comfort performances, how to tune thecharacteristics of suspensions' elastic elements is always abig issue in developing the chassis of a vehicle. In this paper, amulti-body dynamics model of a passenger car within MSC.ADAMS® isintegrated with iSight FD®, an optimization tool, to carry out amulti-objective optimization for improving the behavior of vehiclehandling and ride comfort. The characteristics of suspensionelastic elements (id est, spring, damper and anti-roll bar) areconsidered as design variables. For handling, the objectives aredefined by the measurements from multi-body dynamics simulation oftypical double lane change according to ISO3888 standard. For ridecomfort, the frequency-weighted RMS (Root Mean Square) value ofvertical acceleration of the front seat rail according to ISO2631standard is set as the objective. The optimization methods which issuitable to the multi-objective trade-offs in vehicle developmentare discussed, and some simulation results about the cooperativeoptimization between handling and ride comfort are presented inthis paper
