One Engine Mounting Optimization

Engine mounting system is one of the most important sub-assembly part, most of the engines used in engineering machinery are combustion motor, This kind of engine is of inherent vibration source.A particular engine dynamic model has been set up in this essay, main content:Case of engine incentive generation, mechanism of vibrate isolation in Engine mounting system, vibration system modal theory and experimental verification, analysis based on MATLAB of the Engine mounting system, including the inherent frequency and decoupling matrix, The main work is as follows:1, Searching and reading a large number of relevant essays, study the engine vibration source and vibration characteristics. Study of domestic and foreign research on power train mount components, suspension system optimization design, parameters confirmation in power train mount system design;2, Studying the mechanism of damping rubber in engine mounting system and how to define the stiffness of the damping rubber. The material, frame structure, active suspension system is also included;3, According to determined the object of study, collect related experimental data and technical data in advance for analysis the engine and suspension system;4, Establish six degrees of freedom suspension system coordinates, using the theory of vibration get the Mass matrix and Stiffness matrix, this paper analyzes the cause of the fault of the front mounting bolts;5, Establish the finite element model of suspension system, optimization design for the front engine suspension. Basing on the optimization scheme, investigate the mechanical properties with Hypermesh...
