Abstract

The embodiment of the invention provides a method and device for determining the equivalent acceleration of a rail transit vehicle. The method comprises the steps: obtaining the target speed and the target average acceleration of the vehicle, obtaining the response time from a handle traction instruction to brake release, and the idle running time generated by impact rate limitation, and calculating the equivalent acceleration of the vehicle according to the target speed, the target average acceleration, the response time and the idle running time. According to the method and the device, the response time and the idle running time which influence the equivalent acceleration are considered according to the actual starting process of the vehicle, so that the accuracy of the equivalent acceleration is improved.

Description

technical field [0001] The present application relates to the field of rail transit technology, in particular to a method and device for determining equivalent acceleration of a rail transit vehicle. Background technique [0002] At the beginning of rail transit vehicle design, based on the average acceleration requirement put forward by the designer, in order to achieve this requirement, the output parameters of the traction motor are usually tested according to parameters such as vehicle weight, number of trains, axle data of trains, gear rotation ratio, etc. , and then check the acceleration performance, and adjust the torque characteristic curve of the motor according to the checked result. [0003] In the related technology, considering that the acceleration of the vehicle is greatly affected by the response time and the jerk rate, but the average acceleration proposed above does not take this effect into account, the deductive method is usually used at present, and the...
