Investigation on Accelerated Life Testing of Rubber Parts on Railway Vehicle Braking Products
The failure mechanism of the rubber parts was analyzed based on the actual operating conditions of the rubber parts on the braking products.The characteristic parameters affecting its service life of the rubber parts were determined.An accelerated life model of the certain rubber parts was established based on the Arrhenius model of the rubber parts.The experimental methods of the high-temperature accelerated life testing were investigated under the certain stress.The high-temperature accelerated life testing was conducted on the rubber component of the empty-load valve.The research shows that the method to determine the high temperature acceleration factor is feasible and accurate to validate the service life of the rubber parts on brake products.
