The article proposes a mathematical model of temperature control of a multi-phase gas-hydraulic vibration isolator due to application of gas-regulated heat pipe. During the operation of the vibration isolator with magnetorheological transformers, mechanical energy is absorbed, which is converted into heat. The use of a gas-controlled heat pipe ensures the removal of heat from the object, the creation of an isothermal zone inside it and the temperature stabilization of the object. This ensures the preservation of the working properties of the magnetorheological fluid, in particular, its viscosity, and practically stabilizes the parameters of the amplitude-frequency characteristic of the vibration-insulator, regardless of the time of continuous operation and the ambient temperature. The article presents experimental methods for determining the thermal coefficient and rate of heating of a vibration-isolator, which allows making reasonable design decisions in the design of vibration protection systems.
