With the increasing number of vehicles in the world, the problems of environmental pollution and lack of responsibility for oil resources are becoming increasingly prominent. Because of its advantages of green environmental protection, diversification of energy sources, and high energy efficiency, all countries in the world are actively working to research and develop electric vehicles …

With the vigorous development of the electronic industry, all kinds of electronic products and electric products have gradually become indispensable tools for people to use, and the batteries closely related to them have gradually attracted people’s attention. Among them, the safety of the battery itself is the focus of attention. A battery with potential safety …

Environmental conditions are the key factors that affect the quality and reliability of equipment. For equipment used in the environment where the ambient air temperature changes rapidly, the impact of temperature shock environment is a factor that must be considered. This environment brings a variety of typical environmental effects to equipment, such as deformation or …

1.Volume Selection When the tested product (components, components, parts or complete machine) is placed in the climate environment chamber for testing, in order to ensure that the tested product The ambient atmosphere can meet the environmental test conditions specified in the test specifications. The following provisions shall be followed between the working dimension of the …

1.Test Overview The impact experienced by the products during use and transportation is mainly due to the impact caused by the emergency braking and impact of vehicles, the air drop and crash of aircraft (emergency landing), the launch of artillery, the explosion of chemical energy and nuclear energy, the ignition separation and re-entry of missiles …

When satellites, space probes and other spacecraft are operating in space, they are in a thermal vacuum environment of high vacuum, cold black and solar radiation. Vacuum thermal environment simulation test is a very effective ground test method to simulate the vacuum thermal environment (high vacuum, cold black, solar radiation, high temperature and other environments) …

  1.Low Air Pressure Environment Due to the gravity of the earth, the air has a certain weight to form atmospheric pressure. The atmospheric pressure at a certain height is the heaviest of the entire air column on the unit area perpendicular to the ground above the point. With the increase of height, the air …
