Problems solved by technology

[0002] In the prior art, the polygonal wear of rail vehicle wheels is mainly improved by turning and repairing the wheel tread. Wheel repairing can only improve the polygonal wear of rail vehicle wheels in a short period of time. Wear will develop again; wheel turning is used to eliminate polygonal wear by chipping off the wheel surface material, reducing the service life of the wheel, and the economic cost is high

Embodiment 1

[0031] Such as figure 1 As shown, the present embodiment provides a method for controlling polygonal wear of a rail vehicle wheel, which includes the following steps:

[0032] 1. Collect information on polygonal worn wheels of rail transit vehicles, such as operating conditions and on-site data, conduct wheel polygonal wear tracking tests, and obtain wheel polygonal wear data;

[0033] 2. Based on the wheel wear rate and the material wear characteristics of the wheel tread quenching and strengthening treatment, match the wheel selection strengthening parameters at the design trough position;

[0034] 3. According to the strengthening parameters, through the selective quenching and strengthening technology of the wheel tread, the polygonal wear trough position of the wheel is selected and strengthened, and the relative rate ratio of wear between the peak and the trough position of the polygonal worn wheel is increased; image 3 As shown, the wear rate of the wheel material at ...

Abstract

The invention relates to the technical field of rail transit, in particular to a rail transit vehicle wheel polygon abrasion control method which comprises the following steps: 1, collecting information of a rail transit vehicle polygon abrasion wheel, and carrying out a wheel polygon abrasion tracking test to obtain wheel polygon abrasion data; 2, based on the wheel abrasion rate and the abrasion characteristic of a wheel tread quenching strengthening treatment material, matching and designing wave trough position wheel selective area strengthening parameters; 3, according to the strengthening parameters, through a wheel tread selective quenching strengthening technology, conducting selective strengthening treatment on the polygonal abrasion wave trough position of the wheel, and increasing the abrasion relative rate ratio of the wave crest position to the wave trough position of the polygonal abrasion wheel; and 4, when the amplitude between the wave crest and the wave trough of the polygonal abrasion wheel is reduced to a certain value and the abrasion of the strengthening material at the wave trough position disappears, performing uniform area selection intensity treatment on the wheel tread. According to the method, the development of polygon abrasion can be better controlled.

Description

technical field [0001] The invention relates to the field of rail transit technology, in particular to a method for controlling polygonal wear of rail transit vehicle wheels. Background technique [0002] In the prior art, the polygonal wear of rail vehicle wheels is mainly improved by turning and repairing the wheel tread. Wheel repairing can only improve the polygonal wear of rail vehicle wheels in a short period of time. Wear will re-occur and develop; wheel turning is used to eliminate polygonal wear by cutting off the wheel surface material, reducing the service life of the wheel, and the economic cost is high. Contents of the invention [0003] The content of the present invention is to provide a method for controlling polygonal wear of rail vehicle wheels, which can overcome some or some defects in the prior art. [0004] A method for controlling polygonal wear of a rail vehicle wheel according to the present invention, comprising the following steps: [0005] 1. ...
