Product reliability is critical to the development of the enterprise. As an important part of the car, the front axle of the car has an inestimable impact on the overall quality and safety of the car. From the current situation, with the continuous progress of technology, consumers put forward higher requirements for product quality The reliability of automobile front axles has become a factor of great concern in the product design process of Fuhua axle commercial vehicle front axle branches.
Among domestic automobile axle manufacturers, managers have fully recognized the important role of product reliability in promoting the development of enterprises. In the process of designing an automobile, the designer of the automobile has regarded the reliability of the front axle 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 has two main requirements: first, the reliability design of the front axle of the car can meet the design requirements of the entire machine; second, the reliability of the mechanical structure of the axle has a certain stability, will not Changes due to changes in external factors. However, from the actual situation, the reliability of the axle mechanical structure is affected by many factors, often because of changes in external factors. The reliability of the mechanical structure of the front axle of an automobile is often affected differently by these factors, resulting in qualitative or quantitative changes. At present, for the purpose of improving efficiency and reducing costs, it is necessary to conduct in-depth and systematic exploration of the nature and specific degree of the influence of different factors on the reliability of mechanical structures, and to objectively and accurately measure the reliability sensitivity of mechanical structures. After hundreds of years of development, some foreign automobile brands have already achieved considerable reliability. In contrast, the reliability of current domestic automobile axles has not been convincing for a while. At present, in the context of globalization, China's automotive products should be aligned with foreign countries, continue to learn, absorb foreign valuable experience, and strive to reach the world's advanced level as soon as possible. To achieve this goal, axle manufacturers must focus on the design of mechanical structures and continuously improve the reliability of automotive products.
In fact, there are many elements that can affect the reliability of the front axle of the car. The most critical one is the design of the front axle of the car. 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. At present, many automobile product companies have carried out analysis and research on the sensitivity of structural reliability of automobile products. The focus of their research is to analyze the impact of different variables on the probability of failure in the case of changes in the model, and find the laws existing in them. If there is a large correlation between the failure of the front axle of the car and a certain parameter, then the designer of the front axle of the car must strictly control this parameter when designing, and try to minimize the factors that induce its change. Ensure that auto parts have strong reliability. In another case, if the correlation between the failure of the front axle of the car and a certain parameter is low, then the designer of the front axle of the car 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.
