The reference condition of stress load is a reference point of accelerated test. The so-called reference point refers to the stress load level of the product under normal working environment conditions. This paper takes the automobile wiring harness as the research object, and mainly evaluates the fatigue failure life of the wiring harness in the long-term bending and durable movement of the automobile wiring harness. installation state and bending motion.
In addition, the temperature accelerates the aging and failure of wire harness materials in this process. The temperature of the stress load factor of automobile wiring harness aging is selected as 25 ℃ as the reference benchmark. The application of temperature load is relatively easy. The automotive wiring harness and the tooling are directly placed in a programmable thermostat to simulate the temperature conditions of the automotive wiring harness in different working environments.
