电缆式地层测试器电子线路骨架模态特性分析

Modal Analysis of the Electronic Circuit Framework for Formation Tester EFDT

为分析电缆式地层测试器(EFDT)电子线路骨架的振动特性,避免电子线路骨架固有频率与外界激励频率重合而发生共振,从而引发元器件的破坏,必须对其进行模态特性分析。文中利用ANSYS Workbench软件对电子线路骨架进行模态特性分析,得到其振动的前6阶固有频率与振型,并对模态结果进行了分析,对结构优化设计具有实际应用价值。

In the vibration characteristics analysis of electronic circuit framework for EFDT,the resonance when the inherent frequency of electronic circuit framework is equal to excitation frequency in the outside world will cause damage of components, so modal analysis of electronic circuit framework for EFDT must be conducted.By using Workbench software platform, modal analysis of the electronic circuit framework was calculated. And the first to sixth vibration modes are extracted to analyze and get the natural frequency of vibration modes. The model results are also analyzed. The optimum design of circuit framework could be developed based on the data and result.
