Four-comprehensive-environment test device

Abstract

The invention provides a four-comprehensive-environment test device. The test device comprises a test box, a sample inlet/outlet door, an observation window and a temperature-humidity regulation system, wherein the sample inlet/outlet door and the observation window are located on the test box, the temperature-humidity regulation system is used for regulating and controlling temperature-humidity in the text box, vibration equipment is arranged at the bottom of the test box, the vibration equipment is connected with a vibration control system, the temperature-humidity regulation system and thevibration control system are connected with an environment test control system respectively, a window-door is arranged on each of the two side walls of a box body of the test box, and opening/closingof each window-door is controlled independently through a motor. By the adoption of the test device, both an acceleration test and a natural environment test can be carried out, natural environment factors can be accurately captured in an ocean atmospheric environment, the actual influence of salt mist on a product is accurately simulated, and the test device is suitable for a vibration test on anelectronic product installed on weapon equipment; and the test device also can achieve a temperature, humidity and salt mist enhancing effect in the natural environment, and the phenomenon of condensation cannot occur in the test process.

Description

Technical field [0001] The invention relates to a four-integration (the four-integration in the present invention refers to the four factors of temperature, humidity, salt spray and vibration) environmental test device for the detection of electronic products on military equipment in a marine environment. Background technique [0002] The environmental conditions in the coastal waters of southeast my country are extremely harsh. Weapons and equipment that have been in service in this area for a long time, especially military warships, have been affected by environmental factors such as high temperature, high humidity, and salt spray for a long time, resulting in electronic products on the equipment (such as communication equipment, navigation equipment, Radar, weapon control system) performance degradation or failure. In order to evaluate the reliability and service life of electronic products on weapons and equipment, it is necessary to carry out accelerated tests on such electro...

Problems solved by technology

[0003] At present, temperature and humidity vibration devices or equipment are mainly used to carry out accelerated tests on electronic products on weapons and equipment under laboratory conditions. Because laboratory conditions can only simulate preset temperature, humidity, and vibration conditions, electronic products on weapons and equipment except In addition to the influence of temperature, humidity and vibration factors, it is also often affected by factors such as temperature and humidity changes, salt spray concentration changes, etc., resulting in insufficient simulation of the actual working conditions of such electronic products by laboratory accelerated tests

Although CN207964229U discloses four comprehensive experiment machines for temperature, humidity and high vibration, including a support base, two groups of I-shaped slide rails are arranged in parallel on the top of the support base, and a support frame is arranged in parallel on the top of the two groups of I-shaped slide rails, and the support frame and the I-shaped slide rails are arranged in parallel. There are two sets of rolling pulleys symmetrically arranged between the slide rails,
