Different decreasing vibration methods were adopted because of the different position.The isolation vibration instruments were installed in the position of electric generator,they can decrease the force of electric generator;the effective subframe can decrease the vibration when the vibration was transferring.The tracker and the laser were installed on the platform of isolation vibration,the platform of isolation vibration is made up of air spring and electromagnet.Using several isolation vibration methods at the same time can decrease vibration effectively and keep the tracking and measuring system work normally from experiment and simulation results.
