摘要

本文使用应变计对某型发动机临界转速下的机匣振型进行了了测试分析，同时也对发动机机匣进行了动态特性理论分析。测试分析与理论计算结果均表明用应变计测试机匣的振型是一种有效的测试方法，同时也为发动机状态临测和结构修改提供了理论依据。
In this paper,measurement and analysis of the casing vibration model for sometype engine at its critical rotation speed is preserted. Meanwhile, the theoretical analysis of the dynamic characteristis for the engine casing has been made. The measurement and analysis and theoretical computation show that measuring casing vibration model by use of strain gauge is a ethetive measurement method and the theoretical basis for monitoring engine condition and revising structure is provided.
