基于GB/T 2423.10-2019正弦振动试验的试验方法研究

Research on Test Method Based on GB/T 2423.10-2019 Sinusoidal Vibration Test

振动试验是评价开发产品或模型在未来的使用工况中可能受到外界复杂的作用力或自身共振对自身影响的一种力学可靠性环境试验。随着现代工业产品工艺的日益科学化,工业产品的可靠性要求随之越来越高,所以振动试验成了可靠性试验中必不可少的部分。日常的振动试验主要分为正弦振动和随机振动两大类。本文结合标准GB/T 2423.10-2019《电工电子产品环境试验第2部分:试验方法试验Fc:振动(正弦)》,对具体振动试验过程中出现的不满意试验结果进行分析,并就相关技术问题展开技术探讨。旨在让试验人员可以对振动试验的技术要点有更深刻的理解或延伸。

Vibration test is a kind of mechanical reliability environmental test to evaluate the influence of complex external forces or self-resonance on the developed product or model in the future use conditions.With the increasingly scientific technology of modern industrial products,the reliability requirements of industrial products are becoming higher and higher,so the vibration test has become an indispensable part of the reliability test.The daily vibration test is mainly divided into two categories:sinusoidal vibration and random vibration.This article combines the standard GB/T 2423.10-2019 Electrical and Electronic Products Environmental Test Part 2:Test Method Test Fc:Vibration(Sinusoidal),analyzes the unsatisfactory test results during the specific vibration test process,and discusses related technical issues start a technical discussion.It is designed to allow testers to have a deeper understanding or extension of the technical points of vibration testing.
