针对应用于可调谐二极管激光吸收光谱(TDLAS)技术研究中的一种简单的集成化光学系统，利用ANSYS有限元分析方法，建立系统有限元模型，分析了系统模态和谐响应特性；通过振动台实验测试了系统结构的动力学特性，获得系统结构在不同动力载荷作用下的幅频曲线。结合数值模拟和测试结果，分析获得系统抗振性能，给出了系统所能承受的环境振动频率范围。结果表明：该光学系统在900 Hz以内的振动环境下具有良好的抗振性能，可以应用于现场测试诊断。

With ANSYS software, the finite element anasysis of the integrated optical system based on tunable diode laser absorption spectroscopic technology(TDLAS) was built, numerical modal and harmonic response were analyzed. Based on the shaking table test result, the system structural dynamic properties, the amplitude-frequency curves under different dynamic loadings were measured in experiments. Then, combined with calculation results and test results, anti-vibration performance of optical system was analyzed, and frequency swing of environment vibration in which system can work was got. Result shows that system can work within 900 Hz environment vibration. It has the capability of testing and diagnosis outside the lab .
