机耕船壳体是机新船的易损件之一。为了研究它的磨损问题,本文先对船壳与土壤中硬磨粒两者间进行了力学状态分析。然后,在自行研制的干、湿两用振回转盘式磨损试验机上进行了一系列控制单因素的模拟试验。根据试验结果探讨了壳体的磨损形式,从而初步找出了影响其磨损的主要因素。 Machine-hull shell is one of the vulnerable parts of a new machine. In order to study its wear problem, this paper firstly analyzes the mechanical state between the hard shell in the hull and the soil. Then, a series of single factor simulation tests were carried out on the self-developed wet and dry vibrating rotary disc wear tester. Based on the test results, the wear forms of the shell were discussed, and the main factors affecting its wear were found.
