Vibration Simulation and Experimental Verification of High-power Tractor Cab
摘要
Abstract
For the problems of tractor vibration and driver fatigue caused by road roughness,this paper takes High-power Tractor as the research object,establishes a six degree of freedom man chair road tractor vibration model based on vehicle dynamics theory,and simulates the vibration transmission process of man chair system under tractor dynamic conditions.Real vehicle tests were carried out in the field and on asphalt roads to measure the vibration acceleration of tractor seat and human head,waist and leg under dynamic conditions.On the one hand,it was compared with the model simulation results.On the other hand,through the time-domain and frequency-domain analysis of acceleration response,taking the weighted root mean square value of acceleration as the evaluation index,the vibration comfort of the driver is evaluated and analyzed.The results show that the established man chair system model is highly consistent with the results of vibra-tion test,the model has good prediction effect,and the discomfort caused by vibration at the driver's measuring part from low to high is head,leg and waist,which can provide a reference for tractor vibration reduction and seat design.关键词
