Abstract

The sensitivity analysis and design of flexible suspension parameters of hanging devices were proposed to improve the first order vertical bending frequency of the fully equipped car bodies.The vertical bending frequency was optimally designed with the thickness of body frame as design variables based on the modal sensitivity analysis theory.The influence of suspended forms and rigidity of rubber on the first vertical bending frequency was analyzed.The results show that the first vertical bending frequency of the car body can be changed from 9.70 Hz to 10.60 Hz while the mass of car body was increased by 0.93 t.The first vertical bending frequency of FE models of fully equipped car bodies was enhanced to 10.51 Hz by adopting the method of flexible suspension while the mass of the car body was constant.In contrast with the sensitivity analysis,the design of flexible suspension parameters of hanging devices is easier for engineering application and the mass of car body is constant.
