摘要

控制器局域网(can总线)是机械设备数字控制的默认解决方案。can总线结构使用连接器组件来扩展布线和连接子系统。连接器是ip分类的,因此它们可以容忍湿度和颗粒进入。入口保护也提供了抗其他压力因素的耐久性。通常,连接器暴露在多种应力因素下,但应力水平是持久的。然而,在采矿应用中,应力水平可能很高,其他因素也变得很重要,因此IP分类不一定表明足够的耐用性。量身定制的测试可用于识别适合特定用途的组件。本研究采用某井下钻机的实际应力因子进行了定制试验。结果表明,具有相同IP代码的连接器型号之间的可靠性存在显着差异。组件的排名取决于所使用的应力因素。这突出了在评估可靠性时使用实际运行条件的重要性。

Reliability evaluation of CAN-bus connectors with tailored testing
ABSTRACT Controller Area Network (CAN-bus) is a default solution for digital control in machinery. The CAN-bus structure uses connector components to extend cabling and join subsystems. The connectors are IP-classified, so they tolerate humidity and particle ingress. Ingress protection also provides durability against other stress factors. Usually, connectors are exposed to multiple stress factors, but the stress levels are durable. In mining applications, however, stress levels can be high, and other factors become significant, so IP classification does not necessarily indicate sufficient durability. Tailored testing can be used to identify suitable components for a specific purpose. In this study, the actual stress factors of an underground mine drill were used in tailored tests. The results showed significant differences in reliability between connector models with the same IP code. The ranking of the components varied depending on the stress factors used. This highlights the importance of using actual operating conditions when evaluating reliability.
