摘要:

自动张紧器是发动机前端附件驱动系统(front and accessory drive, FEAD)中,用于减小张紧轮两侧带段张力波动和带段横向振动位移的主要零部件之一. 张紧器的静态力学特性的评价参数包括张紧器的静刚度、初始扭矩和阻尼系数. 介绍了张紧器力-位移曲线的实验方法,以及张紧器扭矩-角位移曲线、性能评价参数的求解方法. 张紧器静态力学特性实测数据,为FEAD 系统静态、动态特性计算提供数据基础. 实验方法为类似旋转运动件的扭转静刚度测试提供参考.

Abstract:

The automatic tensioner is widely used in the engine's front end accessory drive (FEAD) system. It plays a predominant role to reduce the dynamic tension and the transverse vibration of the belt span adjacent to the tensioner pulley. The static performances of a tensioner are characterized by three parameters including the static stiffness, the pre-torque and the damping coefficient of the tensioner. Experimental methods for measuring the tensioner force versus the displacement are presented. Also, the data processing techniques for establishing the curve of the tensioner torque versus the angular deflection, and for evaluating the parameters of the tensioner static performances are illustrated. The experiment results provide a validation for the modeling and the simulation of the static and dynamic performances of the FEAD system. The experiment techniques presented in this paper can also applied to measure the static stiffness of similar structures.
