Abstract:

An analytical model for the dynamic response of a bistable fluid amplifier with straight walls is presented. The model represents the dynamic changes which take place in an amplifier during the early phases of switching. The state of the amplifier at any instant of time is identified by a set of system equations whose input function is the mass flow rate from the control port. The system variables, constants and equations are arranged in nondimensional form in order to organize and facilitate the solution. In the second half of the report, the system equations are used to prepare an analog simulation of the amplifier. The coupling between system variables and the feedback mechanisms present in the model can be easily identified from this simulation.
