Abstract

Abstract

In order to test the air quality in real-time, an optical and mechanical structure of on-truck infrared detection equipment is designed. Using large aperture optical system, high precision scanning structure and unfocus reflecting telescope, the system achieves 0-360 scanning in orientation and pitching. The structural static analysis of the system is performed using finite element method and the results meet the optical and mechanical design requirements. A modal test is done by hammer beat method and a vibration test is carried out under the on-truck environment. Comparing the two results above, the first-order frequency of the optical and mechanical structure is 52 Hz, which has sufficient dynamic stiffness corresponding to the 12.5 Hz in the on-truck environment and can ensure the stable operation of infrared detection devices.
