[0002] A swing test bench is a device used to test and evaluate the performance of mechanical systems, structures or components in a dynamic environment. It can simulate dynamic forces such as vibration, shock and swing under actual working conditions to ensure that the tested object can work normally or meet specific performance requirements under these conditions. Swing test benches are widely used in aerospace, automotive, shipbuilding, construction, electronics and other industries to test the durability, reliability and performance of various equipment and components. For example, aircraft components are subject to complex aerodynamic loads and vibrations during flight, and a swing test bench can simulate these conditions to verify the design and manufacturing quality of the components.

[0003] The swing test bench is usually composed of a bearing base, a drive system, a control system, a sensor and a data acquisition system. The bearing base is responsible for supporting and fixing the object to be tested, while ensuring stability and accuracy in a simulated dynamic environment. At present, most swing test benches use a relatively firm fixing method to fix the object to be tested in order to ensure stability in a dynamic environment. The fixing components are usually customized according to the size of the object to be tested.
