Environmental Simulation

The large-sized space environmental simulation test facility is mainly used for providing thermal radiation environment in high-vacuum, cold and dark space for satellites, spacecraft, lunar spacecraft to carry out whole satellite thermal vacuum test and for large equipment like antenna to carry out tests in TV conditions. Monitoring the spacecraft’s surface optical image or temperature is a main task in space environment simulation test. In previous tests, optical image test mainly took place in a fixed position, so the measuring location and angle are limited. This paper focuses on large spherical space environmental simulation test facility, and designs a large arc-shape high-precision walking device in a space environment simulation test device. It introduces key technology in detail like structure design, thermal design, processes and manufacturing, etc. The test results show that this device can work steadily and reliably under simulation space environments, and the precision exceeds 0.5°.

The artillery test of firing simulation provides the similar dynamic recoil effects of artillery, by means except firing. It is more safe and convenient with less ammunition and time consumed. This document describes the meaning and content of the artillery test of firing simulation. It analyses the feasibility of this test technology by calculating and comparing the experimental data of guns and makes a research and analysis for current situation and development of the related technology In the domestic and overseas. Through fuzzy comprehensive evaluation (FCE) and analysis hierarchy process (AHP), a comprehensive assessment on different simulation techniques is done. A research direction on the artillery test of firing simulation is proposed, which can meet the requirements of the development of modern artillery.
