Abstract

Abstract The technical conditions and service life of steering elements of vehicles are an important factor directly affecting road safety. Therefore, high reliability of such kind’s components is required. In the paper, on the basis of the stand test, the fatigue durability of a ball joint of a steering tie rod is determined. It is elaborated together with a prediction for the further number of cycles, enabling to determine the technical state of the tested component containing its service life. The aim of the article is to select an appropriate mathematical model with respect to describing the relationship between the moment of force and the fatigue cycles performed for the ball joint of a steering rod of a vehicle with a GVW above 3.5 tonnes, and identifying the model’s parameters. As a result, the limit number of loading cycles after which the examined joint does not meet safety requirements is estimated.

球接头疲劳寿命预测

车辆转向元件的技术状况和使用寿命是直接影响道路安全的重要因素。因此，对此类元件的可靠性提出了较高的要求。本文在台架试验的基础上，确定了转向拉杆球接头的疲劳耐久性。它与对进一步循环次数的预测一起详细阐述，从而能够确定包含其使用寿命的被测部件的技术状态。本文的目的是选择一个合适的数学模型来描述GVW在3.5吨以上的车辆转向杆球节的力矩与疲劳循环之间的关系，并确定模型的参数。结果，估计了被检查节点不满足安全要求的极限加载循环次数。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
