Abstract: Aiming at the test of reliability for shipboard electric appliances in the laboratory environment, a new mechanism of tilting and swaying was proposed. The structure of the test bench was designed to realize the horizontal and vertical movement of the two horizontal axes, a stepping motor was used as the driver, PLC and inverter were set up to control angle and speed of the test bench, two sensors were installed to detect the real pose situation, which can form a closed loop control system with the use of the touch screen and the relays.This device has the advantages of high precision, light weight and low manufacturing cost compared with the traditional tilting and swaying test bench .The typical test results indicate that the bench can satisfy the requirements of the GD012006, which is called Chinese Guidelines for Type Approval Test of Electric and Electronic Products. The test results also show that the bench can monitor and modify the parameters in real time , it can work safely and reliably, it also can test accurately and effectively due to the alarm function.The test bench has strong practical application value.
