摘要
建立了发动机前端附件驱动系统张紧装置阻尼系数的数学表达式,并通过了实验验证;进而研究了该张紧装置的结构参数对其阻尼系数的影响规律。结果表明:扭簧中径、摆臂与摩擦片摩擦因数和摩擦片外径是影响其阻尼系数的主要因素。
A mathematical expression for the damping coefficient of tension device for the front-end accesso- ry drive of engine is established and verified by experiments. Then the effects of the structural parameters of tension device on its damping coefficient are studied. The results show that the pitch diameter of torsion spring, the friction coefficient between swing arm and friction dise and the outer diameter of friction disc are the main factors influencing the damping coefficient of tension device.
