Discussion on the Multiple Load Identification and Measurement Method of Rail Vehicle Coupler
With the increase of the speed and load of heavy duty truck,the performance of coupler is more de-manding,and and it is necessary to obtain the actual load spectrum of coupler in longitudinal,transverse and vertical directions.However,the traditional monitoring technology can not meet the requirements,so this paper proposes a multi-load decoupling temperature self-compensation full bridge measurement technology.Through establishing a theoretical model,arranging strain arrays and designing bridge groups,accurate measurement and zero drift compen-sation of strain on each hook surface are achieved,and finally the effectiveness of the technology is verified through experiments.This measurement technology provides a scientific means for monitoring the coupler load of rail ve-hicles.
