| 摘 要： | 根据材料力学理论建立了活塞环环向应变与径向压力之间的关系式。用电测法测出活塞环内缘一系列点的环向应变值,采用最小二乘法将测得的应变值进行处理,得到环向应变的分布规律,利用建立的关系式计算出活塞环径向压力分布。

| Abstract: | The relation between hoop strain and radius-directional pressure was set up based on the theoretics of mechanics of materials.The values of hoop strain for a series of points on the inside of piston ring were measured using the strain gage technique.The values of hoop strain were disposed of by applying the method of least squares,and the hoop strain distribution was obtained.The radius-directional pressure of piston ring was determined using the relation between hoop strain and radius-directional pressure. |
