Ploughbreast is the crucial soil-engaging component of horizontally reversible plough (HRP). Its biggest merit, compared to conventional ploughs, is to enable the ploughbody to perform alternative and shifting tillage operations with high speeds. A major technical challenge in the aforementioned operation is violent flowing interaction between soil and ploughbreast. This flowing interaction may result in severe wear rate on the ploughbreast, particularly along its cutting edge, i.e. ploughshank, thereby reducing the tool life. The objective of the present paper is to evaluate influences of the flowing interaction on the ploughshank by studying interaction force, wear rate and their correlation. The interaction forces were predicted using a numerical calculation with finite volume approach in computational fluid dynamics (CFD) software. The wear rates were measured using scanning electron microscope (SEM). There were very good qualitative agreements between numerical and experimental results that either the maximum force or the most severe wear rate appears at the same section and has a direct relationship with the Tillage speed and tilling depth. Closer examination of the calculated and measured confirms that the more violent sliding & rubbing, the greater stress gradient and the larger abrupt stress cause the more severe wear rate along the ploughshank.

犁胸是水平可逆犁（HRP）的关键土壤接合组件。与传统犁相比，它的最大优点是使犁体能够高速执行替代耕作和轮作耕作操作。上述操作中的主要技术挑战是土壤与犁pl之间剧烈的流动相互作用。这种流动的相互作用可能导致犁胸，特别是沿其切削刃，即犁齿，严重磨损，从而缩短了刀具寿命。本文的目的是通过研究相互作用力，磨损率及其相关性来评估流动相互作用对犁the的影响。在计算流体动力学（CFD）软件中使用有限体积方法进行数值计算来预测相互作用力。使用扫描电子显微镜（SEM）测量磨损率。数值和实验结果之间有很好的定性一致，即最大力或最严重的磨损率出现在同一部分，并且与耕作速度和耕作深度直接相关。仔细检查计算得出的结果，可以确认，滑动和摩擦越剧烈，应力梯度越大，突变应力越大，沿犁ough的磨损率越严重。
