| Abstract: | By analyzing the contact mechanics of the automotive fuel level sensor, a wear model for the fuel level sensor was established using the numerical discretization method. The parameters of this model were obtained by dry wear durability experiment. The reliability life of the rivet and the track was evaluated using Monte Carlo method. The results showed that the proposed numerical model and reliability prediction results of wear life could be applied to the wear simulation of the fuel level sensor. |
