基于VPG白噪声滤波模型在四轴车体系统驾驶室的平顺性研究
Research on ride comfort of cab in four axle car body system based on VPG white noise filtering model
摘要
Abstract
Producing random road incentive model of virtual test station VPG road under the white noise filtering method ,vehicle dynamics model of the four axis heavy semi-trailer train mechanical system ,based on energy method using dynamic equations .In the micro vibration assumption of space system is simplified as a planar system ,will add a new saddle consider-ing the stiffness and damping parameters of a domestic vehicle dynamics model parameters to build good ,through the ode15s module of MATLAB system for vehicle for solving differenti-al equations after specific 1/2 vehicle cab relative dynamic load and vibration response from the results of computer simulation system ,and measured the same road level speed difference comparison ,finally the simulation method and experimental evaluation method and study the four axle vehicle cab ride .This method provides a new idea for the development of many axle heavy truck considering the saddle condition and the dynamic simulation of the vehicle road coupling field .关键词
