Problems solved by technology

Traditional infrared target simulators generally use high-power bulbs as simple targets, which have large spots, poor parallelism, and difficult energy control, which cannot meet the requirements of missile tests. Therefore, new infrared target simulators must be used to realize a new Vibration Stress Screening Test Requirements for Mid-Range Infrared Guided Missiles

Abstract

The invention provides mid-range infrared target simulator equipment. A modular combined structure is adopted, and the mid-range infrared target simulator equipment is mainly composed of an infrared optical system, a one-dimensional rotating platform system, a lifting mechanism and the like, wherein the infrared optical system comprises a black body, an adjustable diaphragm, an adjustable attenuation slice, a collimator assembly, a light-shading hood and the like, horizontal rotating and locating of a platform within a certain range are achieved through the one-dimensional rotating platform system, and the accuracy is 0.1 degree, and the lifting mechanism mainly completes overall up-and-down rising and falling of the equipment and achieves whole-distance fine tuning and the self-locking function; and moving rolling wheels and a fixed mechanism are designed on the bottom face of the equipment, and moving and transporting and the testing stability requirement of the equipment are achieved. The mid-range infrared target simulator equipment has the advantages of being convenient and easy to use, attraction in equipment, easy to maintain, long in service life and the like, and infrared target simulation in certain-type mid-range infrared guidance missile vibration environment stress screening tests is successfully achieved.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a mid-range infrared target simulator device, which is used for a missile vibration environment stress screening test. Background technique [0002] Vibration environmental stress screening test is an important link in the missile development process. Stress screening tests are carried out on missiles under specified vibration stress conditions to induce defects in product design, process and manufacturing, and eliminate early failures, thereby improving product reliability. The seeker is a key component of the missile product, and its working performance needs to be monitored during the whole process of the vibration environment stress screening test. During the test, an infrared target simulation device was placed directly in front of the missile, the seeker intercepted and tracked the infrared simulated target, and it was observed whether the seeker could trac...
