摘　　要：以齿形分别为ZA和RU的汽车同步带为研究对象,在相同实验条件下,对同步带传动进行振动试验研究。基于两轮无负载振动试验台,分别进行齿形为ZA和RU的变转速变、变张紧力的振动试验。利用多普勒激光测振仪测试同步带紧边带背的振动幅值。通过对比可以得出结论:相同试验条件下,ZA型同步带的振动幅值比RU型汽车同步带的振动幅值要大。The synchronous belts with the teeth shapes of ZA and RU are respectively taken as the research objects.Under the same experimental condition,the vibration test of the synchronous belt transmission is carried out.The vibration tests of variable speed and tension force with teeth shapes of ZA and RU are carried out respectively based on two-pulley non-loaded vibration test device.The vibration amplitude of synchronous belt tight side belt back is measured by using laser doppler vibrometer.A conclusion can be drawn by comparison that the vibration amplitude of ZA type synchronous belt is larger than that of RU type synchronous belt under the same test condition.
