Piston Pin Testing

Abstract

This thesis addresses a study undertaken to develop a finite element model and perform quasi-static tests. The test is to simulate the piston and connecting rod execute a pressure force on the piston pin in a Honda CRF250F motorcycle. A variety of different piston pins are introduced to analyse how the mechanical strength of the pins is influenced depending on the change of their inner shape. By analysing the quasi-static tests conducted, an iterative process is performed to reduce the weight but maintaining the desired strength parameters at the same time.
