Abstract

Any work of soil-processing machines is accompanied by abrasive wear of working bodies and, first of all, their blades with the characteristic formation of rear chamfers on them. The use of methods and bench equipment for accelerated simulation loads in this study allowed us to determine the areas of normal pressure plots on the friction surfaces and predict the consequences of wear results. It was found that an increase in the angle of the rear chamfer as a result of wear increases the area of the plots of normal pressure on the blades, while increasing the energy consumption and reducing the quality of work. The research results obtained in this paper are proposed to be used in the development of new designs of working bodies of soil-processing machines.

在磨料磨损过程中改变土壤处理机叶片的加载条件

摘要

土壤处理机的任何工作都伴随着工件的磨损，首先是其叶片，并在叶片上形成了特殊的倒角。在这项研究中，使用方法和工作台设备来加速模拟载荷使我们能够确定摩擦表面上的正常压力图区域，并预测磨损结果的后果。已经发现，由于磨损而导致的后倒角角度的增加增加了叶片上法向压力图的面积，同时增加了能量消耗并降低了工作质量。建议将本文获得的研究结果用于开发土壤处理机工作体的新设计。
