Abstract
In order to extend the service life of key rubber components for subway vehicles,this paper proposes a life prediction method based on accelerated life tests.The accelerated life test is conducted for the door finger guard rubber and passageway rubber on subway vehicles,using new rubber and rubber that has been in service for five years.During the tests,the elongation at break,tensile strength,and hardness of the door finger guard rubber,and the hardness of passageway rubber were tested.A quadratic function was used to fit the variations of each parameter of the rubber,and the remaining life of the rubber was predicted by converting the acceleration time to determine the corresponding actual service time of the rubber.The results show that new rubber and rubber that has been in service for five years show different performance trends in the acceleration test,and by predicting the remaining life of different rubbers,it can provide a theoretical basis for the extension of the service life of rubber parts for subway vehicles.关键词
