为了改善汽车的使用情况,需要研究零部件的磨损、累积疲劳损坏等等。但这仅是问题的一方面,属于微观的范畴。从宏观来说,汽车使用部门必须掌握全部车辆技术状况的变化规律,才能采取经济合理的技术措施,以提高它们的完好率。研究汽车技术状况变化规律的理论有多种,如机械可靠性理论、机械存续理论、更新理论等等。本文对更新理论作一单简的介绍,希望引起汽车运输界技术同行的注意,开展这种理论的研究工作,并在实际工作中应用。
In order to improve the car’s use, we need to study the wear and tear of components, accumulated fatigue damage and so on. However, this is only one aspect of the problem and belongs to the category of microscopic. From a macro perspective, the automobile use department must grasp the changing law of the technical condition of all the vehicles in order to adopt economical and reasonable technical measures to improve their intact rate. There are many theories to study the changing law of automotive technology, such as mechanical reliability theory, mechanical survival theory, renewal theory and so on. This article gives a brief introduction to the theory of renewal, hoping to arouse the attention of the technical counterparts in the automotive transport industry, carry out the research work of this theory and apply it in practical work.
