Life testing machine is a type of testing machine used to test or verify the suitability of a product or equipment for use under a specific environmental simulation, the time to effectively complete its function, the number of effective use, and to detect its aging fatigue value.
Life testing machine categories
Storage life testing machine: equipment product reliability test simulated in the specified environmental conditions for non-working state of storage test, called storage test life machine. Storage testing machine needs more test samples and long-term observation and measurement to make a better expectation and evaluation of the product. In order to shorten the test time can be stored to accelerate the test, accelerated storage test is often used to achieve high temperature storage.
Working life testing machine: the product under the specified conditions for the test of adding load. Life test is divided into continuous working life and intermittent working life test. Continuous working test is also divided into static continuous working and dynamic continuous working test two. Intermittent working life test is characterized by periodic work and stop work, dynamic continuous work is uninterrupted continuous work.
Accelerated life test machine: in order to shorten the test time to save samples and test costs, rapid evaluation of product reliability, it is necessary to accelerate the life test; In addition, due to the current process level, conventional test methods to determine the level of product reliability is difficult, so it is also necessary to use accelerated life test method; The third point is that the speed of product updates is too fast, the conventional test time can not catch up with the speed of product elimination, can only Accelerated life test method or other methods can only be used to determine the reliability level of the product. Accelerated life test method has constant stress accelerated life test mode, step stress accelerated life test mode, sequential stress accelerated life test and other modes. Life testing machine
