Development and Application of an Electric Servo Control Support Device
This paper is guided by ASME RT-2-2014 safety standard for heavy rail transit vehicle structure require-ments.In the process of tensile and compression test of coupler part of test car body and compression test at anti-climb device,it is difficult to ensure that the force sensor at the center pin or empty spring support keeps the data unchanged,and the car body is subjected to longitudinal loading force.The vertical mass of the car body shall not be applied to the test requirements of the loading equipment,and the test technology of controlling the change of each force sensor support-ing the body mass is less than 100 kg is studied.In order to solve the problem of large change of vertical force at the sup-port of the car body during the test,an automatic lifting bogie is designed to adjust the change of vertical supporting force of the car body by controlling the electronic lifting device.It is verified in the course of experiment.
