dual axis angular vibration turntable high performance vibration calibrate bench
It is dual axis automatic frame-based mechanical shafting ground test equipment. It is mainly used to simulate the vibration process when carrier launch, to test the bearing capability and tracking accuracy of inertial navigation system under angular vibration situation. It is controlled and data processed by computer, capable of return zero, positioning, vibration function and with advantage of high measure accuracy and high dynamic performance.
