摘要

摘要: 多轴随机振动试验能够同时激发结构在不同方向的模态，使动力响应表现出比单轴振动更为丰富的共振峰，因此对经受多轴振动环境的产品开展疲劳损伤机理分析很有必要。文章围绕多轴随机振动环境疲劳损伤机理的技术现状和发展趋势进行初步分析，调研多轴随机振动环境疲劳损伤机理的研究现状，为多轴振动试验及可靠性试验方法研究提供了理论依据；并为多轴振动系统的原理研究和相关试验设备的优化设计奠定了理论基础。

Abstract: Multiaxial vibration is used as an environmental test method, which is more real and effective than the ordinary vibration test. Fatigue damage methods under multiaxial random vibration are discussed in this paper, including the current state and developing trend of the fatigue damage methods under multiaxial random vibration environment. The proposed theoretical methods can be used in the design of multiaxial test equipment.
