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...

AI Technical Summary

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, a height adjustment bracket is installed on the top of the supporting frame, an installation frame is installed on the top of the height adjustment bracket, an experimental box is installed on the top of the installation frame, and the side walls of the experimental box are symmetrically arranged. There are two groups of observation windows. The left side of the outer wall of the experimental box is provided with a movable door. The outer wall of the movable door is respectively provided with a lead wire test hole and a locking pull rod, and the locking pull rod is set on the right side of the lead wire test hole. There is a control panel on the right side of the outer wall of the body, a test slot is provided at the bottom of the rear wall of the experimental box, and a movable bottom plate matching the test slot is set on the rear side of the experimental box. Although the experimental machine can provide high temperature and low temperature , damp heat, and vibration alone or in combination, but it cannot truly simulate the actual working conditions of electronic products on weapons and equipment, and cannot be used for vibration tests of such products
