| Abstract: | An exposition on a new kind(patent) combination typed crankshaft for long travel and heavy load was carried out systematically.With the adoption of finite element method,the analysis,computation and comparison of the variation rule of stress and the maximum stress value have been carried out on various supporting structures of the combination typed tri-turned crankshaft and the integer tri-turned crankshaft.By considering the factor of redundancy of the supporting structure in the integer tri-turned crankshaft and utilizing the elastic contacting element in the finite element analytical method,the influence of redundancy factor on the value of stress was analyzed.Differences of dynamic characteristics of various supporting structures in the combination typed tri-turned crankshaft and the integer tri-turned crankshaft have been compared. |
