摘　　要：平地机推土板参数对作业阻力的影响很大,关于如何优化平地机推土板的几何参数降低作业阻力的相关研究很少。借助离散元仿真软件,对平地机推土板工作过程进行仿真分析得到:当入土角度为39°,圆弧半径为500 mm,后板高度为200 mm时,作业阻力最小,比原推土板作业阻力降低8.8%;入土角度和圆弧半径对作业阻力有显著影响,后板高度对作业阻力无显著影响。Parameters of a dozer blade of graders affect greatly on the operational resistance,however,few relevant research work to optimize geometric data and reduce the resistance has been done thereto.A way out has to proceed with simulations and analyses during operation of the dozer blade,and the results show that given a cutting angle 39°,a radius of 500 mm,and height of the backplate of 200 mm,the dozing resistance becomes minimal that can reduce the resistance by 8.8%,for the cutting angle and radius have obvious effects onto the operating resistance,whereas no obvious effects onto the resistance from height of the back-plate.
