某发动机皮带轮高温扭转疲劳测试台架设计与应用
Design and Application of a High Temperature Torsional Fatigue Test Bench for an Engine Pulley

发动机作为汽车动力源是其振动噪声的主要来源，而发动机皮带轮作为发动机外部高速旋转部件，其参数和性能对发动振动机噪声的影响尤为重要，本文以某发动机皮带轮为例设计了发动机皮带轮高温扭转疲劳测试台架，用于测试及验证真实工作温度环境下的发动机皮带轮耐久性能，并最终证明设计方案切实可行。
The engine as a vehicle power source is the main source of its vibration and noise, and the engine pulley is an external high-speed rotating part of the engine. Its parameters and performance are particularly important for the noise of the engine vibrator. This paper takes an engine pulley as an example to design the engine pulley high temperature torsion the fatigue test bench is used to test and verify the durability of the engine pulley under the real working temperature environment. And finally prove that the design scheme is feasible.
