Experimental Analysis of Surface Pressure Distribution of Piston Pin Hole

Abstract

Abstract:

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.

Key words: pressure indicating film, piston pin hole, surface pressure, distribution
