中文摘要:为研究新型船用钢板的摩擦磨损性能,用UMT 3 TriboLab摩擦磨损试验机测试这种钢板在不同环境温度下的摩擦因数(载荷为50 N、往复速度50 mm/s),用白光干涉仪测量试样磨痕截面轮廓线,用ABAQUS对Al2O3球与这种钢板组成的摩擦副建模。将测量得到的相关参数输入到计算模型中,采用区域网格划分方法对接触变形过程进行模拟,得到接触区域的应力、应变和塑性变形。结果表明:在球与钢板接触初期,在同等载荷情况下,钢板的磨损量随温度的降低而增加;摩擦磨损过程中的温升、过渡层和磨屑对摩擦磨损行为有一定的影响;采用区域网格划分方法可以有效计算钢板的理论应变和磨痕截面轮廓线;由于摩擦磨损过程中温升、磨屑等因素的存在,基于赫兹接触理论的有限元模拟结果与实际磨损结果有一定的误差,试验环境温度越低,该误差就越小。

Test and simulation of friction and wear performance between new marine steel plate and Al2O3 ball
Abstract:To investigate the friction and wear performance of new marine steel plate, UMT 3 TriboLab friction and wear tester is used to test friction factors of the steel plate at different environment temperatures (the load of 50 N and the reciprocating speed of 50 mm/s), the white light interferometer is used to measure the cross section profile of the wear scar, and ABAQUS is used to model the friction pair composed of Al2O3 ball and the steel plate. The measured parameters are put into the calculation model. The contact deformation process is simulated to get the stress, strain and plastic deformation of the contact area, where the method of regional mesh division is adopted. Results show that: at the initial stage of contact between the ball and the steel plate under the same load, the wear volume of the steel plate increases with the decrease of temperature; the temperature rise, the transition layer and the wear debris in the process of friction and wear have some effects on friction and wear behavior; because of the regional mesh division method, the theoretical strain of the steel plate and the cross section profile curve of the wear scar can be calculated effectively; due to the existence of temperature rise, wear debris and other factors in friction and wear process, the finite element simulation results based on Hertz contact theory have some errors compared with the actual wear results, and the lower the temperature of test environment, the smaller the error caused by the above factors.
