METHOD FOR ROBUST DESIGN OPTIMIZATION FOR RIDE COMFORT

摘要

PURPOSE: A robust optimal design method toward the ride comfort of a vehicle is provided to increase the ride comfort and robustness. CONSTITUTION: A robust optimal design method toward the ride comfort of a vehicle comprises: a step of producing a car ride feeling assessment index; a step of reading car ride feeling sensitivity; a step of optimizing the ride comfort by selecting a factor relatively affecting big influence on the car ride feeling as a design variable; and a step of produce the optimizing ride comfort step by using the BFGS(broyedn-fletcher-goldfarb-shanno) algorithm based on the slope.
