| 摘 要： | 以销—盘滑动模型为对象,研究钴基合金的摩擦磨损行为,预测大尺寸接触对的磨损状况。通过自主研发的磨损试验机获得钴基合金Stellite6材料的磨损量随磨程、速度和压力的变化规律;在试验与模拟相结合的基础上,建立滑动磨损过程的预测模型,实现节点移动和单元更新过程的自动递推,完成磨损各个阶段的动态仿真,并构建实现磨损过程全自动数值仿真的平台,应用于大尺寸耳轴—轴套模型的磨损预测。结果表明,基于销—盘滑动试验,采用有限元法来离散磨损过程,通过非线性计算实现的磨损仿真结果具有较高的可靠性和有效性。

| Abstract: | The friction and wear behavior of Co-based alloy is researched based on pin-on-disc model in order to predict wear loss of large-size contact pair.A pin-on-disc experiment with self-designed device is done to get the law of wear loss of Stellite6 influenced by grinding-process,sliding speed and pressure.Based on experiment results,a sliding wear prediction model is established by combining the law and finite element method,while dynamic simulation of the whole wear process is achieved by moving boundary nod... |
