3-Axis/ 2-Axis ship swing test bed is the key equipment of dynamical performance experiment for shipboard equipment. It is used for simulating the movement attitude of the ship and the submarine under the condition of the sea environment. It is widely applied in the performance test of the shipboard electro-optical equipment, navigation equipment, gyroscope and platform gyrocompass etc. This simulation bed is utilized to perform the simulation test, so that it can save a plenty of manpower, material sources and financial resources, can also shorten the lead time of the product. The different simulators developed by utilizing the technology may be applied in aviation, aerospace and arm industries.
