With science and technology development, vibration testing as the most important item in reliability test is becoming more and more important, at the same time, vibrate condition becoming more and more complicated, the phenomenon increases that the output of controller goes beyond controlling range so that destroy the specimen. In this paper, some skills such as how to set the parameters of force controller, where to place the sensor, which material to be chosen and which skills to be used while making jigs where introduced to avoid the just matter. At last, soem examples were given to prove the validity of the method proposed.
