Due to the continuous innovation of technology and manufacturing process, the life of the slip ring is greatly improved. It is difficult to obtain the life information the slip ring under normal working conditions in a short time. In order to quickly obtain the life information of the slip ring, JINPAT specifically gives the experimental design of the accelerated life test of the slip ring.

The accelerated life test is based on the rational engineering and statistical assumptions, using the statistical model related to the physical failure law to convert the information. Then obtain a reproducible numerical estimate of the product at the rated stress level. The accelerated life test is a method that shortens the test period by increasing the test stress (such as temperature, brush pressure, vibration, humidity, voltage, current, etc.) while maintaining the failure mechanism. Accelerated life testing uses accelerated stress levels for product life testing, which reduces test time, increases test efficiency, and reduces test costs.
