In technical practice, problems associated with material fatigue often arise. These problems can be caused by errors in the stages of design, production or use of the structure, e.g., by incorrect determination of service life, incorrect dimensioning of construction details, incorrect welds, etc. In the case of welds, such issues may be caused due to the fact that the base material is not welded through or due to the presence of a fistula inside the weld, the presence of slags or cracks inside the weld, etc. The task of the designer is to design a technological unit that meets all the requirements of future users. Components have to be designed for fatigue so that there is an acceptable level of probability that their operation will be satisfactory during their operation life. One of the most common causes of failure of welded joints is fatigue. Fatigue design life is understood to be the reference period of time during which the structure is required to serve safely and not to fail with an acceptable probability. This article deals with the assessment of service life of a welded supporting structure of technological equipment. The structure was subjected to strength analysis. The obtained FEA results were needed to plot the extreme amplitudes of the stresses. Based on the obtained stress vibrations and the welds used, the service life of the structure was assessed by means of the standard.

机器人工作场所技术设备的终身评估

在技​​术实践中，经常会出现与材料疲劳相关的问题。这些问题可能是由结构设计、生产或使用阶段的错误引起的，例如，使用寿命的错误确定、施工细节的尺寸错误、焊缝错误等。在焊缝的情况下，这些问题可能是由于母材未焊透或由于焊缝内部存在瘘管、焊缝内部存在熔渣或裂纹等而引起的。设计者的任务是设计一个满足未来用户的所有要求。组件必须针对疲劳进行设计，以便在其使用寿命期间其操作令人满意的概率水平是可接受的。焊接接头失效的最常见原因之一是疲劳。疲劳设计寿命被理解为要求结构安全使用并且不以可接受的概率发生故障的参考时间段。本文讨论了工艺设备焊接支撑结构的使用寿命评估。该结构进行了强度分析。需要获得的 FEA 结果来绘制应力的极端幅值。根据获得的应力振动和使用的焊缝，通过标准评估结构的使用寿命。该结构进行了强度分析。需要获得的 FEA 结果来绘制应力的极端幅值。根据获得的应力振动和使用的焊缝，通过标准评估结构的使用寿命。该结构进行了强度分析。需要获得的 FEA 结果来绘制应力的极端幅值。根据获得的应力振动和使用的焊缝，通过标准评估结构的使用寿命。
