Abstract
Thrust vector control (TVC) actuation system is an important part for swing angle control of the nozzle of the launch vehicle. This communication studied a new type of powered electrically actuator: electro-mechanical hydrostatic actuator (EMHA) for driving the nozzle. The key components of the system were firstly introduced and then the mathematical models were presented. The hierarchical method was used for modelling, the models were built from the functional and behavioral—based on the bond graph. Finally, the simulation analysis of the two models is carried out in AMESim virtual prototype simulation environment. This paper shows different levels of models can be used when consider the different engineering needs such as controller design and the energy loss analysis of the system.
