Performance verification and simulation of the hillside crawler tractor for crossing the longitudinal slope obstacle
摘要
Abstract
Hillside crawler tractors are often used in hills and mountains where the working conditions are always complicated.Therefore,they should have general features of a crawler tractor and the ability to cross obstacles in a sloping field.In this paper,a three-dimensional geometrical model of a hillside crawler tractor was draw using the Pro/E software.Configuration of the crawling devices and building a multi-body model and a ground model were achieved in the three-dimensional dynamics software RecurDyn.Based on the three models,a dynamic simulation was conducted to analyze the effects of different speed,slope angles,and centroid position on the longitudinal obstacle performance of the hillside crawler tractor in a sloping field.The results showed that,at certain speed and angles,the closer the centroid position to the front part of the tractor and the ground,the better the longitudinal slope obstacle performance of the tractor.The experimental results are in good agreement with the simulation results,which further validates the correctness of the simulation model and provides a theoretical reference for the further improvement of hillside crawler tractors.关键词
