Method and device for calculating parameters of workshop vibration absorbers

Abstract

The invention discloses a method and a device for calculating parameters of workshop vibration absorbers. A track model is built on the basis of an actual track; then according to the track model, thecoupler lengths of a first compartment and a second compartment, a distance between the centers of a first bogie and a second bogie of the first compartment, and initial position coordinates of the first and second workshop vibration absorbers, actual position coordinates of the first and second workshop vibration absorbers are calculated out; and according to the actual position coordinates of the first and second workshop vibration absorbers, the parameters, such as the lengths, the angles and / or the like of the workshop vibration absorbers, of the first and second workshop vibration absorbers can be calculated out. It can be seen that, in the process of calculating the parameters of the workshop vibration absorbers, a track does not need to be drawn again, so that the process of calculating the parameters of the workshop vibration absorbers is simplified to a great extent, and the problem of wrong estimation of maximum telescopic amounts of the workshop vibration absorbers due to only consideration of special positions can be avoided.

Description

technical field [0001] The present application relates to the technical field of shock absorbers, in particular to a method and device for calculating parameters of shock absorbers in workshops. Background technique [0002] During the running of the train, if the line conditions are complex, two adjacent carriages on the train may move with each other, which will lead to a change in the geometric state of the workshop connection device. Usually, in order to avoid the change of the geometric state of the workshop connection device, the workshop longitudinal shock absorber (referred to as the workshop shock absorber) can be installed longitudinally at the ends of the two adjacent carriages, and the tension of the workshop shock absorber or the Compression to inhibit mutual movement between two adjacent carriages. However, in practical applications, the amount of tension and compression that the workshop shock absorber can withstand is limited. Therefore, it is necessary to c...
