DURABILITY TESTING DEVICE FOR THE PERFORMANCE EVALUATION OF A DRIVING APPARATUS IN WHICH REPETITIVE DYNAMIC LOAD IS APPLIED

摘要

PURPOSE: A durability testing device is provided to offer a conflict testing device which is suitable for a shock test of high frequency by offering the shock frequency of a wide band and to widely secure the margin of an allowable error when executing designing and assembling processes.;CONSTITUTION: A rotating bar(130) has one end which is hinge-coupled in one end of a frame. A rotary shaft(142) is inserted in the other end of the rotating bar. A rotation body(150) is arranged with the rotary shaft as the center and is circulated and driven. The rotation body comprises a plurality of elasticity shock bodies(155) which strikes a testing target(200). The rotation body has a first rotating plate and a second rotating plate which is separated each other. The elasticity shock body of a first group which is coupled to the first rotating plate and the elasticity shock body of a second group which is coupled to the second rotating plate alternately strike the testing target.;COPYRIGHT KIPO 2012
