What is an ultra-low temperature impact testing machine?
In the fields of science and technology and industry, ultra-low temperature impact testing machine is an important testing equipment used to simulate the performance of materials or products in extreme low temperature environments. This article will introduce in detail the definition, working principle, application fields and popular models currently on the market of ultra-low temperature impact testing machines.
1. Definition of ultra-low temperature impact testing machine
Ultra-low temperature impact testing machine is a device specially used to test the impact resistance of materials or products under extreme low temperature conditions. It simulates low-temperature environments and detects fracture, deformation or other physical property changes of materials under low-temperature impact. It is widely used in aerospace, automobile manufacturing, electronic appliances and other fields.
2. Working principle
The working principle of the ultra-low temperature impact testing machine mainly includes the following steps:
1.Sample preparation: Process the materials or products to be tested into specimens according to standard sizes.
2.Low temperature environment simulation: The temperature in the test chamber is reduced to the set value through the refrigeration system (usually reaching -196°C or even lower).
3.Impact test: In a low temperature environment, apply impact force to the sample and record its fracture or deformation.
4.data analysis: Analyze the impact resistance of the specimen through sensors and software systems.
