摘要：The farm vehicle combined switch(VCS)being multifunctional and irregular,the evaluations for them have been difficult problems,which has gotten VCS manufacturers and their users into troubles.So some of their users have still been evaluated VCS with the hand touch-feeling method.In order to make the evaluation more scientific,an integrated test facility,which have three kinds of bionic robot hands(twist,push and draw-out type),and its evaluation mothed were developed for VCS.Meanwhile,some tests,which consisted of subjective tests(experts hand touch-feeling)and objective machine tests,were made to examine this technique.The aim of the tests was to grade the same kind of VCS products among three different manufacturers.By comprehensive analysis,a conclusion can be obtained that there is a significant correlation between the subjective expert method and objective machine one in the VCS evaluation.With regard to machine one,the contributions of the parameters such as the shifting force,inflection force and effective shifting time to the evaluation of VCS are major.This machine evaluation technique can be used to describe and grade the quality of VCS products,and ultimately examine their material,process and assembly,which can be a useful method for authorities who make decisions during production,sourcing/buying as well as design of VCS.
