Research on Fatigue Life Forecast for Torsion Shaft of Self-Propelled Gun under Stochastic Loads

摘要：

　　Torsion shaft is the important buffer and damping component of Self-Propelled Gun.Its main failure mode is fatigue fracture.In order to forecast the fatigue life of torsion shaft under stochastic loads,virtual prototyping of Self-Propelled Gun is established in Pro/E and ADAMS.A new kind of measurement method of load spectrums combining actual equipment experiment with virtual prototyping is firstly put forward in this paper and provides complete and accurate load spectrums of torsion shaft.Stress and strain spectrums can be obtained based on materials S-N curve.The fatigue life of torsion shaft can be forecasted,which provide adequate reference for the maintenance cycle confirmation and mission reliability forecast.
