工程因素对结构振动环境试验响应的影响
Effects of Engineering Factors on Structure Response in Vibration Test
工程因素如试件装配技术状态、试验夹具、控制点位置、载荷控制等对振动试验结构响应的影响一直受到广泛的关注。分析了振动试验中几种主要的工程因素对响应的影响；分析表明，振动试验的识别结果可以预测稳定结构在使用环境下的振动响应。
Effects of engineering factors such as fixture boundaries, assembly connections, dynamic vibration loads position and level, etc., on response of complicated structure in vibration test are investigated. It is shown that evaluations on the response of structure in service are applicable using vibration test information.
