Problems solved by technology

This type of device has high requirements on the accuracy of the centrifugal acceleration generated by the centrifugal testing machine. The existing equipment realizes the adjustment of the centrifugal acceleration by adjusting the angular velocity of the centrifugal testing machine. This adjustment method causes large changes in the centrifugal acceleration and low precision. It is difficult to meet the test requirements; and this type of equipment cannot realize the dynamic adjustment of the acceleration test direction of the test device, and it needs to be switched manually by stopping the machine
