Abstract

The invention discloses a pantograph contact force load processing method and device. The method comprises the following steps: acquiring pressure data and acceleration data of the pantograph in a first time period, and determining contact force load data of the pantograph in the first time period based on the pressure data and the acceleration data; determining mean value distribution information and amplitude distribution information corresponding to the contact force load data of the pantograph in the first time period; based on the mean value distribution information and the amplitude value distribution information, determining contact force mean value extreme value load data and contact force amplitude extreme value load data of the pantograph in a second time period; and grading the contact force mean value extreme value load data and the contact force amplitude extreme value load data of the pantograph in the second time period to obtain contact force load spectrum data of the pantograph. According to the invention, the problem that the condition of the pantograph-catenary contact force load of the pantograph in the life period is difficult to know in the prior art is solved.

Description

technical field [0001] The present application relates to the field of rail transit safety engineering, in particular to a pantograph contact force load processing method and device. Background technique [0002] At present, the main energy source of trunk railway trains and urban rail trains is electric energy, and the energy transmission is mainly carried out through the contact between current collectors and catenary or catenary rails. [0003] As one of the common current collectors, the pantograph is more widely used in trunk railways and urban rail transit because of its ability to withstand higher transmission voltage and transmit greater power. The pantograph-catenary coupling system is composed of the pantograph and the catenary, and its coupling dynamic performance is an important constraint on the speed-up of railway trains. With the increase of train speed, the pantograph-catenary relationship shows that the contact force fluctuates more violently and the off-li...
