活塞环切向弹力测量系统研究

Research on Measuring System for Tangent Elasticity of Piston-ring

论述了活塞环切向弹力测量系统的原理、测量数据处理方法、切向弹力与开口间隙变化的最小二乘直线拟合方法、活塞环开口闭合点和活塞环达到闭口间隙时的切向弹力的评定。

This paper relates the measuring principle of measurement system for tangent elasticity of piston ring, method of measuring data processing, optimun fitting method of least square line for tangent elasticity when piston-ring arrived in close clearance.
