根据实验资料，本文对МИХЦРОВ．П．А．提出的铲取阻力计算力学模型与方法进行了以下改进．（１）、滑移面随铲斗的回转而同向变化．（２）、铲取阻力和铲装物料量在料堆高度和插入深度不同时，其计算公式有所不同，应分别计算．（３）由于是确定铲取过程任一时刻的铲取阻力与铲装物料量，它随铲取轨迹和具体铲装条件而变，只能通过计算机解决．本文编制了运算和优化程序．根据改进后的计算，计算值与实验值比较一致．解决了原模型与方法，实验值与计算值相差大的问题．
According to the experimental data, this article to МИХЦРОВ. П. А. The proposed shovel resistance calculation mechanics model and method are as follows. (1), the slip surface changes in the same direction with the rotation of the bucket. (2) The calculation formulas for shoveling resistance and shoveling load are different when pile height and insertion depth are different and should be calculated separately. (3) Because it is to determine the shoveling resistance and the amount of shoveling material at any moment during the shoveling process, it varies with the shoveling trajectory and the specific shoveling conditions and can only be solved by a computer. This article has compiled algorithms and optimizations. According to the improved calculation, the calculated value is in good agreement with the experimental value. Solve the original model and method, the experimental value and calculated value difference between the big problem.
