Decoupling Study of a Powertrain Mounting System with Effect of a Compliant Base
摘要
Abstract
In order to achieve the TRA decoupling of a powertrain mounting system in the full vehicle model,a coupling model with a compliant base(flexible chassis,suspensions,wheels) and power-train mounting system was established analytically. The accuracy of the model was verified by comparing the natural frequencies of the compliant base with the finite element method. The effects of compliant base on the coupled motions of a powertrain mounting system were analysed. A method of the TRA decoupling for the powertrain mounting system in the full vehicle model was proposed based on the modes' properties and decoupling index of the coupled system. The simulation and experimental results indicate that:the TRA of a powertrain mounting system in the full vehicle model is indeed decoupled and the vehicle comfort is improved when the proposed method is satisfied.关键词
