Embodiment Construction

[0021] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] A multi-functional sand and dust environment simulator with a variable test section generally includes a circulating air duct, a mobile test section air duct, a test chamber, a sand and dust material circulation system, an air conditioning system, and various connecting pipes and valves. The circulating air duct is used to provide uniform airflow that meets the requirements in different test places during the test; the mobile test section air duct is used to provide a place for sand blowing and dust blowing tests for small and medium test objects; The dust test site; the sand and dust material circulation system is used to provide sand and dust raw materials, and form a gas-solid two-phase flow that meets the requirements in the test site, and at the same time recycle the sand and dust materials; the sand and dust material circulation sys...

Abstract

A multifunctional sand dust environmental simulation device with a changeable test section is characterized in that a circulation air flue (1) is included, the circulation air flue (1) comprises a changeable test section, and the changeable test section comprises a test chamber (2) and mobile air flue parts (101, 102, 103 and 104). The invention provides the multifunctional sand dust environmental simulation device which can be used for carrying out integral testing to large-scale test subjects (such as armored vehicles). The multifunctional sand dust environmental simulation device not only can be used for carrying out sand blowing and dust blowing tests to small and medium-sized test objects, but also can be used for carrying out sand blowing and dust blowing tests to the entireties of the large-scale test objects (such as vehicles), can form gas-solid two-phase flow with uniform sand dust concentration and velocity distribution inside an effective experimental space, thereby achieving the technical effects of meeting testing conditions and improving equipment utilization ratio.

Description

technical field [0001] The invention relates to a multifunctional sand dust environment simulation device with variable test sections. Background technique [0002] Sand dust is an environment often encountered in the use of engineering equipment and military weapons and equipment, and has an important impact on the reliability of equipment. Therefore, it is very necessary to conduct sand-dust environment simulation tests on engineering equipment and military weaponry. [0003] At present, the sand and dust test equipment is generally a closed-loop air duct, and the sand blowing and dust blowing tests on small and medium-sized test objects are mostly carried out in the test section in the air duct. But, just can't carry out in the air channel that is suitable for small and medium-sized test object to the sand blowing dust test of large-scale test object (as armored vehicle) whole body, this type of test needs huge test cabin, and such large-scale sand-dust test equipment is...
