Description
technical field [0001] The invention relates to a test device, more precisely, the invention relates to a three-dimensional motion test device which can accurately simulate three-dimensional motion for a test piece. Background technique [0002] In the modern motion machinery control system, the sensor is an essential component. In order to detect and adjust the motion state of the machinery, signals such as inclination, speed, and acceleration are usually measured. For example, in the aviation model, sensors are required to detect the three-dimensional angular position of the model space, and in the automotive electronic stability system, sensors are required to detect the longitudinal and lateral acceleration of the vehicle and the yaw rate of the vehicle, etc. Therefore, the performance of the sensor directly affects the performance and stability of the overall system. [0003] With the development of microelectronics technology, the sensors in motion machinery are becom...
