Experimental Research on Riding Comfort of Mining Dump Trucks
摘要
Abstract
Vehicle comfort has a serious impact on the driver's physical and mental health. In order to study the ride comfort of mining dump trucks driving on random roads, this article takes a 110 t mining dump truck as the research object. A 10-DOF dynamic model for the mining dump truck is established to study the influence factors of the vehicle comfort. Meanwhile, the in-situ test and analysis are conducted on the random road in the mine area. The time domain response, frequency response and ride comfort of the vehicle under different working conditions are obtained. The result indicates that as the vehicle speed increases, both the acceleration magnitude and the frequency of the the road excitation increase, resulting in poor vehicle comfort. With the increase of vehicle’s load, the frequency of road excitation decreases and the vehicle’s comfort improves.关键词
