Modeling and Design Analysis of a Temperature Amplifier for HMC based on AMESim
The temperature amplifier is used in temperature compensate units in HMC(Hydro-Mechanical Control, for aero-engines). The amplifier is a kind of hydromechanical linear servo system. It converts the temperature signal(in type of fuel pressure) to linear output which is used to correct HMCs rotary speed command This paper presents a model for a hydro-mechanical amplifier. Firstly, the structural characteristic and working principle are introduced, then the mathematical model of amplifier is established based on theory of hydromechanics and control laws. The relationship between key parameters and performance are studied from design perspectives, which is thought to be applicable for reverse design and adjustment The analysis reveals the effects that certain structural parameters have on amplifiers static and dynamic characteristics. The modeling and analysis are accomplished with AMESim simulation environment. Verification of the model is carried out using actual test data and the analysis is coincided by simulation result.
