Simulation Analysis and test Verification of the Powertrain

Mounting System of a Small Helicopter

Fan Wang-ming,Song Jun,Li Cheng-You

[Abstract]The powertrain suspension system is an important system that isolates the vibration of the powertrain and guarantees the normal operation of the helicopter equipment. The multi-degree-of-freedom simulation analysis of the powertrain mounting system based on CAE analysis software is used to solve the frequency and mode shape of its modal type, evaluate its vibration isolation efficiency, and prove the vibratio

1 概述

动力总成是通过悬置系统安装在机身框架上的,悬置系统需承受动力总成的质量,以及在受到各种外界干扰力作用的情况下,悬置系统应能有效地限制动力总成的最大位移,以避免与相邻零部件相撞。(剩余3232字)
