A swing test adjustment method and a swing test system

Abstract

The invention provides a swing test adjustment method. The method comprise steps of detecting the actual swing period of a current gear swing table; determining whether the actual swing period is notequal to an expected swing period or not, when the actual swing period of the swing table does not coincide with the expected swing period, controlling the input value of a controller to a driving device step by step, changing the input value of the driving device to make the actual swing period equal to the expected swing period, and using the adjustment input value as the actual input value of the current gear to control the test process to be more accurate and to reduce test errors. The invention also provides a swing test system, wherein a driving device arranged on a support base drives acrank to rotate, the crank drives a swinging handle to swing and then drives a swinging table to shake, and a device under test fixed on the swinging table is shaken; a sensor for detecting the swingperiod and the tilt angle is provided, rotation speed of the driving device is controlled by a wireless controller, and the system can achieve the same technical effect of the above adjustment method.

Description

technical field [0001] The invention relates to the technical field of test adjustment, and further relates to a swing test adjustment method. In addition, the present invention also relates to a swing testing system. Background technique [0002] The rocking table is a kind of equipment for testing the satellite antenna, which simulates the ups and downs of the ship and tests the stability of the satellite. The existing swing table is connected by a wire harness, and the connecting wire is accommodated in a special cabinet. The controller and the control panel are connected through the wire harness. The control panel outputs operation instructions to the controller, and then the controller controls the actuator to shake. [0003] The traditional wire control method takes up a lot of space, which affects the flexibility of the device; and when the actuator wears out or the load increases or decreases, the actual swing period will deviate from the predetermined period, and t...
