Abstract:

For avoiding the blindness of previous reliability test for the powertrain of passenger car, a new method of varying-speed enhancement test correlated to the customer's real operation condition is presented. With the method, based on the test data collected on the rough roads of proving ground and the typical customer roads, the relevant cumulative fatigue damages of driving shaft for all grades of torque are calculated. The total fatigue damage of the driving shaft for 90% customers is simulated with Weibull distribution and Monte-Carlo method, and the enhancement coefficient of varying speed test on proving ground is obtained, providing a technical basis for rational evaluation on the reliability of car powertrain and the formulation of test specification.
