Static steering resisting moment of tire for heavy multi-axle steering vehicle

Wang Yunchao1,Gao Xiuhua2,Zhang Xiaojiang2(1.College of Mechanical Engineering,Jimei University,Xiamen 361021,China;2.College of Mechanical Science and Engineering,Jilin University,Changchun 130022,China)  
In order to solve the damage problem of steering tie rods for heavy multi-axle steering vehicle,the main influence factors,static steering resisting moment of tire,were tested.Based on the vehicle actual road test,the effects of wheel steering angle,vertical loading,friction coefficient and tire pressure on the static steering resisting moment of tire were analyzed.The test data fitting analysis of main influence factors was done by Matlab software.The experimental formula of static steering resistance moment was provided.The prediction error rate of the formula was less than 10% by the verification of test data for the same types of tire.The results can provide a certain theoretical and experimental foundation for improving the safety,reliability and matching ability of the hydraulic power steering system.
