| Abstract: | The vibration insulation is first speculated for inline four-cylinder engines.Then,the suspension system of automotive power assembly is modeled based on 6 DOF via rigid dynamical theories.Pertaining to the qualitative analysis on the bespoke model,a high-performance suspension system is then investigated.Based on simulation technologies,a specific power assembly,which contains a four-cylinder diesel engine and a clutch,is next applied for vibration insulation analysis and solutions.Finally,the accuracy of ... |
