Sandstorm environment simulation test table

Abstract

The invention relates to a sandstorm environment simulation test table which comprises an envelop enclosure, wherein a sandstorm simulation system, a test room and a control system are arranged inside the envelop enclosure, the sandstorm simulation system is composed of a circulation air duct, a blower, a sandbox and a dust remover, the test room is provided with at least one air inlet and at least one air outlet, a tested part is placed inside the test room, the blower, the sandbox and the dust remover are communicated with the circulation air duct in sequence, and the sandstorm simulation system and the test room are connected with the control system. The sandstorm environment simulation test table is capable of simulating a high-speed sand blowing environment under the condition of desert climate, and providing good experimental conditions for testing resistance to the desert climatic environment of all related parts, equipment and devices in production of a passenger train.

Description

technical field [0001] The invention relates to an environment simulation test platform, in particular to a sandstorm environment simulation test platform for simulating high-speed sandstorm conditions, and belongs to the technical field of rail vehicle performance verification test equipment. Background technique [0002] With the development of high-speed railways, high-speed railway projects in windy and sandy areas at home and abroad have gradually been put on the agenda. Usually, windy and sandy weather is accompanied by high temperature radiation and other climates. In order to ensure the safe and reliable operation of EMUs, it is necessary to carry out system analysis and ground verification in advance for systems in windy sand, high temperature and radiation environments. In terms of wind and sand resistance, domestic air conditioners have rich experience and successful achievements in the design, development and application of air conditioners, but the corresponding...

AI Technical Summary

Problems solved by technology

Among the existing sand blowing test benches in China, the sand blowing test benches built by air-conditioning manufacturers can only carry out sand blowing tests, and cannot verify and analyze high-speed sand blowing conditions.

Electric and electronic equipment also has research on wind-sand test benches, but they cannot meet the requirements of high-speed sand-blowing tests, and the equipment is placed in it, so it can only be tested when the equipment is without electricity, and cannot be used for operation tests.
