With science and technology development,vibration testing as the most important item in reliability test is be-coming more and more important,at the same time,vibrate condition becoming more and more complicated,the phe-nomenon increases that the output of controller goes beyond controlling range so that destroy the specimen.In this pa-per,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 were introduced to avoid the just matter.At last,some examples were given to prove the validity of the method proposed.
