中文摘要：

推土板工作过程中,土壤的应力波动情况直接受到推土板触土曲面形状的影响。选择3种具有代表性曲率形式的推土板触土曲面为研究对象,即圆弧形、抛物线形、仿生推土板,采用有限元法进行仿真分析。从推土板工作过程中触土曲面形状对其周围土壤的应力波动影响的角度,来分析触土曲面形状对推土板减阻效果的影响规律。结果表明,在本研究的给定条件下,仿生推土板的应力分布形式相对较合理,其工作阻力相对较小。本研究对于通过探索工作状态下土壤应力波动规律,从而指导推土板触土曲面的减阻节能设计方法具有一定的参考意义。

英文摘要：

During the operation of a bulldozer,the shape of the bulldozing plate＇s soil-engaging surface directly affects the stress of the soil disturbance.This paper takes 3different bulldozing plates with representative curvature forms as research object.These include circular bulldozing plate,parabolic bulldozing plate and bionic bulldozing plate.The finite element method was used to simulate the working process in order to study the influence of the shape of the bulldozing plate＇s soil-engaging surface on the significance of operating resistance reduction from the influence of the shape of the bulldozing plate＇s soil-engaging surface on the stress of the soil disturbance of view.The study will benefit the energy-saving design of the bulldozing plate＇s ideal surface under the guidance of exploring the stress fluctuation rule.
