摘要
针对活塞销座孔易失效的问题,采用感压胶片测量活塞销座孔的表面压力数据,利用训练集与测试集对数据分别进行拟合、评价和分析压力分布规律,建立了活塞销座孔压力分布研究的新方法.以某活塞为例,分析了其销座孔表面的压力分布规律,通过对采集的数据进行回归,建立了压力分布函数,较好地反映了活塞销座孔的的表面压力分布,为活塞销座孔的设计、优化和有限元分析提供了理论参考.
Aimed at the problem of easy failure of piston pin hole, a novel method to analyze the surface pressure distribution of piston pin hole was established, in which an experiment was designed to measure the pressure data using pressure indicating film. The training set and test set was used to fit and evaluate the data. A case study of the surface pressure distribution of a piston pin hole was excogitated by training analysis of the collected data, which indicated that the surface pressure distribution could be better expressed. The surface pressure distribution of piston pin hole provides theoretical reference for the design, optimization and FEA of piston pin hole.
