Vehicle Operation Reliability Evaluation Model Under User's Actual Service Condition

Abstract

In order to evaluate the vehicle reliability in the process of user's use, a fatigue pseudo damage reliability evaluation model Based on axle head acceleration is proposed. Based on the acceleration, an improved MINER cumulative fatigue damage model is studied. Based on the model, the influence of user condition, running speed, load capacity and pavement condition on vehicle reliability is discussed. The reliability evaluation model of vehicle operation under the condition of user use is established. The model can be used for on-line, short-term and long-term evaluation and prediction of vehicle reliability.
