팬터그래프 시험설비 개발

초록

This study presents a development of pantograph test facility which is the tester to verify performance, endurance of suspension and dynamic characteristics of pantograph. The test facility consists of performance, endurance and dynamic pantograph testers. With these testers, all kinds of pantograph, such as cross arm type or single arm type, can be evaluated. Using the performance tester, measurement of nominal static force, checking of the operating system, transverse rigidity test, air tightness test, functional check of ADD (Automatic dropping device) and etc. can be examined. With the dynamic tester, the dynamic behavior of pantograph according to the exciting frequency can be tested. Endurance behavior for pan-head spring and continuous upward and downward movements can be evaluated using the endurance tester.
