In this study, the models before and after improving the support structure of seat motor gear nut are investigated by comparing with vibration analysis. The maximum deformation model 1 becomes higher than model 2. The natural frequency of model 2 becomes higher model 1. The design model to be applied into the safe driving is useful effectively by using the analysis result of the height driving module for automotive power seat.
This technology is based on the processing skills by the automatic high speed burner processors to improve the overall productivity and customer satisfactions. The following conclusions could be gained from this research. A burner for processing stone plate was measured to obtain the average 23.8 m/s. Non-slip friction coefficient of the burner after processing was measured to obtain a mean value of 53.2 BPN. Production rate for stone items was measured by the time of the burner and the result passed through the brush was 26.94 m/s on average.
The developed machine is apparatus for laminating papers of high performance. The machine was developed easily to feed paper using servomotor in feeding parts. The existing machine can not shift using mechanical gear ratio in chain driven upper feeder. The advantage of machine can slow down and up the speed of machine and can feed in any position without waiting. Thus, production rate and volume were enhanced. greatly.
This study is investigated by the analyses of modal and harmonic response on BH motor, VI motor and DH motor. The natural frequency of DH motor becomes lower than that of VI motor. As the maximum 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. The deformation of 0.34806 mm happens at the critical frequency in case of BH motor. And the maximum deformation happens at the joint connected between screw axis and seat in cases of three kinds of motors. By applying the result of this study to the designs of these kinds of motors, it is thought that the damage of linked parts is prevented. As the durability can be examined and anticipated, this result can be utilized really
