摘要: SUMMARY A 5-DOF plane vehicle model is studied. randomly profiled road assumed to impart normally distributed stationary vertical random displacements the front and rear wheels. Several performance criteria based on response mean square spectral densities are discussed. It emphasized that these contain more information than do simple standard deviations. computer program has been developed for optimization of two or system parameters make a (or weighted sum responses) minimum. Constraints responses can be introduced. Ride comfort, holding, energy absorption, fatigue failure first-passage Numerical examples given.
