摘要

汽车继电器用于车辆,在正常运行过程中会受到各种机械振动。振动分析有助于确保继电器能够承受这些振动而不发生故障。这对继电器的耐用性和长期可靠性至关重要。在这项工作中,使用电动振动器对继电器进行了振动分析,并获得了电接触电阻(ECR)。由于环境和路面条件的影响,汽车中使用的继电器会产生振动。因此,必须对汽车继电器进行振动分析。ECR 是在频率为 10 Hz 至 70 Hz 的直流和交流静态环境下获得的。振动分析使用电动振动器实验装置进行。使用 COMSOL Multiphysics 进行有限元分析 (FEA),以获得继电器电气触点的电气和机械参数。最高电流密度出现在可视化的接触表面边缘。振动分析检查了继电器电气触点的动态行为。本研究还深入探讨了动态条件下的规定位移、Von Mises 应力和总位移性能。

Vibration Analysis and Electrical Contact Resistance Assessment for Automotive Relays
Automotive relays are used in vehicles, subject to various mechanical vibration levels during regular operation. Vibration analysis helps ensure that the relay can withstand these vibrations without malfunctioning. It is essential for the relay's durability and long-term dependability. In this work, vibration analysis is carried out for the relay using an electrodynamic shaker, and the electrical contact resistance (ECR) is obtained. Relays used in vehicles undergo vibration because of the environmental and on-road conditions. Hence, vibration analysis is mandatory for automotive relays. ECR is obtained under DC and AC static environments with a frequency of 10 Hz to 70 Hz. Vibration analysis is carried out using an electrodynamic shaker experimental setup. Finite Element Analysis (FEA) using COMSOL Multiphysics is carried out to obtain the electrical and mechanical parameters of relay electrical contact. The highest current density occurs at the contact surface edges that have been visualized. Vibration analysis examines the dynamic behavior of electrical contacts in relays. This study also delves into prescribed displacement, Von Mises stress, and total displacement performance under dynamic conditions.
