摘　　要：电工电子产品的环境可靠性验证试验中,通常都少不了冲击试验的存在。冲击[1]试验可以暴露电工电子产品的机械薄弱环节和/或其性能降低和冲击引起的疲劳损伤和老化情况。本文根据标准GB/T 2423.5[1]的冲击试验方法,结合振动台、冲击台的设备原理以及试验数据的差异化分析。旨在让试验人员对半正弦波冲击试验的设备选择有更明确的方向和建议。In the environmental reliability verification test of electrical and electronic products,the existence of impact test is often indispensable.Shock tests can expose electrical and electronic products mechanically weak links and/or their performance degradation and cumulative damage and aging caused by shock.This paper is based on the impact test method of the standard GB/T 2423.5,combined with the equipment principle of the shaking table and the impact table and the differential analysis of the test data.The purpose is to give testers clearer direction and recommendations for equipment selection for half-sine wave shock testing.
