The High Linear Acceleration Of The Temperature In The Heat And Vibration Compound Test Environment Control Technology

This dissertation has a discussion on temperature control of combined experiment environment including high linear acceleration, heat and vibration. The dissertation contains six chapters.In chapter one, it summarizes the status quo of the combined experiment environment research. Meanwhile, it also expounds the aim and significance of the research.In chapter two, the principle of the combined experiment environment system is introduced that includes the structure of the mechanism and control system.In chapter three, the temperature field of heated box is simulated by computer. It supplies the bases of the design of heated box and the control of temperature.In chapter four, the design of circuit and the arithmetic research of temperature control are introduced. Finally, the temperature field of the heated box is tested and the effect controlled by PID arithmetic is compared with Fuzzy arithmetic.In chapter five, multi-computer communication between PC and single-chip computer is introduced in combined experiment environment system and the control of the centrifuge's rotate speed is researched.In the end, the results and the prospects of the thesis are brought forwards.
