Reliability Assessment Calculation of the Automobile Transmission System

Article Preview

Abstract:

In order to improve reliability of automobile transmission system and its running stability, this paper raises a reliability assessment calculation method. This method considers dependent failure of the parts, material strength degradation with increasing load times and uncertainty of load times in micro and macro scopes to explore main factors affecting the system reliability. The feasibility of this method has been validated by the example analysis. As a result , material properties of each gear parts, torques and load times play key parts in reliability of the system.
