Design And Implementation In Infrared Seeker Imaging Facula Measurement Machine

The measuring and experimental technology for infrared seeker is the new requirement in now and aftertime for a long period of time under the development and usement of infrared imaging guided tachnique.The imaging quality and energy distributing of the optical discreteness are extraordinary important to improve the ability for infrared seeker to seach,distinguish,seize and scout the aim,so we must quantificationally examine its imaging quality and energy distributing during the production, in prder to direct production and fitting more effectively.The intelligentized facula measure machine for infrared seeker we have designed is mainly used to measure quantificationanlly the energy distribution on the infrared imaging plate and its permeating rate, and to evaluate the optical system imaging quality,so that to insure it to meet the imaging quality and energy requirement.During the design,we massly used the CAD technique to improve the speed and quality of design,and the standardization of the design.The mechanical design workload of the whole testing system is very plentiful. It involves 42 design,including 5 A0 designs,4 A1 designs,11 A2 designs,9 A3 designs and 13 A4 designs.The paper consists of five sections. Chapter 1 is the introduction.It describes concisely the development of infrared seeker and its testing and evaluating technique,and the key technique in the task. Chapter 2 mainly describes the ganaral knowledge of CAD and its use in design. Chapter 3 starting with the whole design scheme,describes the use and the main technical requirement of the machine,gives the precision requirement and then distributes it,at the end analyzes the principle of the machine and the main difficulty in the mechanical design. Chapter 4 expounds the CAD in the 3 main discretenesses,then analyzes and calculates the errors of the machine,and describes the installation of machanism and the operating process. Chapte 6 summarizes the design of the machine,calculates the whole error and puts forward some suggestion to improve.
