Embodiment Construction

[0033] A method for synchronous debugging of multiple vibrating tables parallel excitation motions of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] see figure 1 , figure 1 A schematic diagram of a four-table parallel-excited vibration test system in a specific embodiment of the present invention is shown; wherein, this specific embodiment uses four parallel-excited vibration tables. The vibration test system of the present invention includes: a vibration controller, a phase shifter, a power amplifier, a Hall current sensor, a vibration table, a control sensor and a signal regulator.

[0035] figure 1 The middle vibration controller 1 sends out the Drive driving signal, passes through the phase shifters 2, 3, 4, and 5, and then enters the power amplifiers 6, 7, 8, and 9 to amplify the signals, and then drives the vibration tables 14, 15, 16, and 17. shaker motion. The control sensors installed on the four vibra...

Abstract

The invention discloses a multi-vibrating stand parallel-excitation movement synchronization debugging method. The method includes the following steps: determining a multi-stand parallel-excitation synchronization debugging target, preparing the wire connection of a test device, initiating the test device, setting parameters of a vibrating control system, measuring the current information of a vacuum stand test, synchronously adjusting the movement amplitude of multiple stands, synchronously adjusting the movement phase of multiple stands, testing expansion stand with loads, and turning off the test device. According to the invention, the method herein aims at ensuring synchronization of multi-stand movement by adjusting power amplification gain and phase compensation. The method herein can prevent multiple vibrating stands from outputting phase reversal and from causing damage to the test device and test products, and can ensure safe and effective operation of the multi-vibrating stand parallel-excitation test system.

Description

technical field [0001] The invention belongs to the technical field of spacecraft mechanical environment test, and in particular relates to a synchronous debugging method for parallel excitation motion of multiple vibration tables. Background technique [0002] Before launch, the spacecraft needs to undergo strict vibration environment test verification to check whether the structural design of the product is reasonable and fully expose the potential defects and hidden dangers of the product. With the continuous development of China's aerospace technology, the research and development activities of super-large spacecraft such as space stations have started, but the thrust of a single shaking table currently on the market cannot meet the mechanical test requirements. Therefore, it is imminent to develop multiple parallel-excited high-thrust vibration test systems. [0003] The multi-shaking table parallel excitation vibration test system is mainly composed of a shaking table...
