dc.description.abstract为了解决长行程水平向振动台中管线对滑台牵拉引起的输出波形失真问题,提出一种带动管线跟踪滑台同步运动的随动装置设计方法.建立管线牵拉力作用下的水平向振动台机电耦合动力学模型,计算管线牵拉力对振动台输出波形失真度的影响;设计一种基于光栅尺的滑台随动装置,带动随动平台与滑台做同步运动,滑台上的管线经随动平台后引出,此时管线的牵拉力直接作用在随动平台上,而滑台上受到的牵拉力趋于零.试验结果表明,通过增设滑台随动装置,水平向振动台在做超低频大行程振动时的输出波形失真度得到极大的改善.
dc.description.abstractIn order to solve the problem of output waveform distortion due to the pipes and wires' tension in a long-stroke horizontal vibration table,a follow-up-gear design technology was put forward which drove the pipes and wires to move synchronously with the slipway.The electromechanical coupling kinetic model of a horizontal vibration table was analyzed considering the tension of pipes and wires in it,and the influences of tension forces of the pipes and wires on the output waveform distortion of the horizontal vibration table was calculated.A follow-up gear for the slipway was developed based on a precise linear encoder,and drove a following table moving synchronously with the slipway.And the pipes and wires on the slipway were led out through the following table,on which the tension forces directly acted,but the tension force on the slipway drove to zero.The experimental results indicate that the output waveform distortion improves greatly after adding the follow-up gear when the horizontal vibration table works in long-stroke and ultra-low-frequency motion.
