Design of a Domestic Commercial Vehicle Radiator Cushion System
In order to solve the jitter problem of a domestic commercial vehicle radiator system,a new type of radiator cushion with feasible system and reliable structure is designed.According to the boundary requirements of the radiator,firstly,the inertial parameters are accurately measured by using the air-bearing rotating platform.The decoupling rate and natural frequency of the system are calculated by Matlab software.The results show that the decoupling rate of each order of the system is greater than 98%,which meets the target requirement of 85%decoupling rate.The natural frequency distribution of each order falls outside 1～10Hz.The frequency interval of each order is greater than 10 Hz to avoid resonance with the engine.Thus,the ideal three-dimensional stiffness result of the radiator cushion is matched.Then,using the ideal stiffness value,the three-dimensional model of the radiator cushion is established by UGNX software.Finally,the finite element simulation software is used to check the strength of the radiator cushion system model,which proves that the structure design meets the requirements.This design provides a successful design case for commercial vehicle radiator cushion.
