Ice accretion and freezing rain vibration comprehensive test system

Abstract

The invention discloses an ice accretion and freezing rain vibration comprehensive test system. The system comprises a first comprehensive environment test box for supplying the test spraying water at a test requirement temperature to a test piece, and a second comprehensive environment test box for supplying an environment temperature required by the test to the test piece. A water storage container is arranged in the first comprehensive environment test box. A temperature sensor is arranged in the water storage container. A rain spraying nozzle is arranged in the second comprehensive environment test box. The second comprehensive environment test box is installed on a vibration table for applying a vibration stress to the test piece. The rain spraying nozzle is connected with the water storage container through a water pipeline. From the outlet of a high-pressure water pump, a first pressure gauge, a water flow adjusting valve, a flow meter, a one-way valve and a second pressure gauge are sequentially arranged on the water pipeline. The pipeline section of the water pipeline, between the one-way valve and the second pressure gauge, is connected with a water-gas mixing valve for introducing the compressed air. The ice accretion and freezing rain vibration comprehensive test system is convenient in operation, simple in structure and good in test effect.

Description

technical field [0001] The invention relates to the technical field of freezing rain test systems, in particular to a comprehensive freezing rain vibration test system. Background technique [0002] The comprehensive freezing rain + vibration test is formulated for a customer based on the special environment that the end plate of its product is subjected to in the actual use environment of the high-speed train. The main purpose is to simulate in the laboratory through the artificial environment whether the end plates of different surface treatment layers installed near the train wheels will freeze under the conditions of vibration, low temperature and splashing water when the train is running, and if it freezes, it needs to be measured thickness and adhesion. Through the icing freezing rain / vibration comprehensive test, the anti-icing effect of different treatment layers can be obtained according to the phenomenon of the test results, so as to provide a supporting basis for...
