Compared with the prior art, the invention has the beneficial effects that:
the bottom plate and the top plate can arrange the oil damper in multiple angles, and the spring can apply tension stress and compression stress on the oil damper, so that comprehensive stress performance test research of the multiple oil dampers under different combinations and different stress conditions can be carried out. The anti-slip materials arranged on the lower surface of the bottom plate and the upper surface of the top plate can effectively resist the horizontal friction force between the device and a test instrument, so that the rigidness of the test process and the accuracy of the test result are ensured.
