Influence of Automobile Axle Failure Mode on the

?????????Judging from the current situation, with the continuous advancement of technology, consumers have put forward higher requirements for product quality, and the reliability of axle products has become a factor of great concern in the axle design process. In China's auto companies, the company's managers have fully realized the important role of product reliability in promoting the development of the company. In the process of designing an automobile, the designer of the automobile has regarded the reliability of the automobile as the core indicator to measure the overall quality of the automobile. From the perspective of the structure of the car, the axle is a key component of the automobile structure, and the safety of the entire vehicle greatly depends on the strength of the axle.

???????In general, the reliability of the mechanical structure of the front and rear axle assemblies of the car has two main requirements: First, this reliability design can meet the design requirements of the entire machine; Second, the reliability of the mechanical structure of the axle has certain stability , Will not change due to changes in external factors. However, from the actual situation, the reliability of the mechanical structure is affected by many factors, often because of changes in external factors. At present, for the purpose of improving efficiency and reducing costs, it is necessary to objectively and accurately measure the reliability sensitivity of different factors on the reliability of the mechanical structure of the axle of the vehicle.

After several hundred years of development, some foreign automobile axle brands have already achieved considerable reliability. In contrast, the reliability of the front and rear axles of domestic cars is still unconvincing. At present, in the context of globalization, China's automotive axle products should be aligned with foreign countries, continue to learn, absorb valuable foreign experience, and strive to reach the world's advanced level as soon as possible. To achieve this goal, we must focus on the design of the mechanical structure and continuously improve the reliability of the front and rear axles of the car.

????????In another case, if the correlation between the failure of an automobile axle and a certain parameter is low, then the designer of the automobile axle product can regard it as a definite value when performing reliability design. In this way, the number of random variables has been greatly reduced, and designers can focus on the random variables that have been known. In view of the fact that this kind of reliability analysis is very complicated and can be completed by non-manpower, the analysis process is often completed with the help of related analysis software, which not only improves the efficiency of the analysis, but also makes the analysis results more objective.
