The vibration process is essentially a kind of force transmission, which may cause damage to the connection part or the main structure component of the test component. The current vibration test device generally tends to use the method of direct connection of the motor through the reducer. The advantage of this method is that it can more conveniently adjust the vibration frequency. The disadvantage is that for some test components with larger mass, the reducer, motor connection shaft, etc. are prone to damage during use. This is actually caused by excessive torque generated by direct connection during forced vibration. Utility Model Content
