台阶路面数学建模和两自由度车辆的响应分析
Mathematical model of the step road and analysis on the response of two DOF vehicle model
摘要
Abstract
The vibration of vehicle caused by step road is mainly studied in tbis paper. By taking the west gate of Henan Polytechnic University as an example , the mathematical model of is derived， and the displacement curve of wheel centroid varies to radius is given. The moving characteristic of half - vehicle model with vertical vibration and bend forward and face backward vibration is analyzed when the vehicle at lower and higher speed rans through the step road of west gate. By comparison of the numerical results, it shows that the vehicle's severe high frequency vibration is caused in running with high speed through the west gare. And the bearing is affected by high frequency alternating stress, which can reduce service life of vehicles and increase consumption of energy.关键词
