This paper introduces the method and steps of the local stress strain method to analyze the fatigue with the application of ANSYS,uses this method to analyze and calculate the fatigue-life of the press-sensor shaft both before the optimization and after the optimization to give the basis of the judgement of how the optimization influences the fatigue damage of the shaft.

By using ANSYS software,this paper calculates and analyses the stress of the shaft of the press-sensor and optimizes some important dimensions and gives the optimized results.

This article introduces structure, characteristic, stress analysis and theoretical calculation of shaft pin cutting type load cell.
