Transfer Function Of Mechanical System. Mechanical engineering questions and answers. Mechanical system draw a free body diagram showing all forces and their directions write equation of motion and derive transfer function of response x to input u chp3 15.
In some simple cases this function is a two dimensional graph of an independent scalar input versus the dependent scalar output called a transfer curve or characteristic. The transfer function for the closed system is hence 1 2 1 i o 1 g g g θ θ g worked example no2 the transfer function for a hydraulic system comprising of a hydraulic valve and actuator is gs 1ts. The transfer function of the mechanical systems likewise can be obtained from the governing differential equations describing the system.
They are widely used in electronics and control systems.
