240/275 Diesel Engine Virtual Prototyping Shaft Kinematics And Dynamics Simulation Analysis

This article was comparing conventional crank linkage organ dynamics analysis to the modern computer simulation technology .setting forth the advantage of the computer simulation technology, and using the dynamic simulation software ADAMS to analyse respectively 240 single-cylinder locomotive and multi-body dynamics simulation analysis of 16V240ZJ locomotive diesel engine Shaft,the computer dynamics simulation carried out a major analysis of the various components of the movement and analysis, 16V240ZJ diesel-balance analysis, as well as flexible crankshaft torsional vibration system analysis, acquire the accurate simulation data, form load spectrum of the Pistons part force. in the Diesel design stage for a balanced analysis of the crankshaft and the Department of vibration analysis for the selection and design of concrete structures designed to provide a basis.In this paper, the combination of the original 240-piston failure modes were analyzed to find the combination of piston-loss effect of the reasons for failure to identify the reasons for the combination of structure pistons analysis of the line, the use of dynamic analysis from a combination of components Pistons load spectrum, as in the I - DEAS software for the Pistons in the calculation of the fatigue strength of parts of the border, to carry out further structural strength of the piston combination of finite element analysis, and further optimize the structure of the piston design, in order to get the fatigue factor of safety for the optimization of the parameters of the optimization program Pistons 240, optimization Pistons in the original program of fatigue from the minimum safety factor of 1.03 to 1.92 minimum, a substantial increase in fatigue safety factor. testing and validating the simulation results , the optimization program in the actual engineering application has been made very good social and economic benefits.
