摘要

为了分析阻尼装置对汽车发动机正时链横向振动的影响

把阻尼装置抽象为单自由度的质量—弹簧系统

利用多自由度系统理论建立基于有限个集中质量分布的链传动横向振动模型

得到模型的振动微分方程。在此基础上

计算了固有频率和主模态

分析了阻尼装置安装位置对系统振型和阻尼装置质量、刚度对链传动横向振动频率的影响

提出了设计阻尼装置的几种措施。

Abstract

A model of transverse vibration of automotive engine timing chain with damper that was modeled as a single degree of freedom system which consists of a mass and a spring was developed from Multi-DOF system theory based on finite centralized mass distributed modeling

and the differential equation of system vibration was established. The natural frequencies and the natural modes were computed

and the effect of the damper where was installed on the system mode shapes and the mass and stiffness of damper on the natural frequency of chain drive system were investigated. Some measures to design the damper in the automotive engine timing chain are presented.
