초록

This study is investigated by the analyses of modal and harmonic response on BH motor, VI motorand DH motor. The natural frequency of DH motor becomes lower than that of VI motor. As themaximum amplitude of displacement is shown to be 2.06×10-2mm at 1300 Hz in case of BH motor,BH motor can be thought to be the best structure in comparison with VI motor and DH motor. Thedeformation of 0.34806 mm happens at the critical frequency in case of BH motor. And the maximumdeformation happens at the joint connected between screw axis and seat in cases of three kinds ofmotors. By applying the result of this study to the designs of these kinds of motors, it is thought thatthe damage of linked parts is prevented. As the durability can be examined and anticipated, this resultcan be utilized really.
