Main Battle Tank Flexible Gun Tube Disturbance Model: Three-Segment Model

摘要

A rational approach to disturbance rejection is proposed and applied to a simple three degree-of-freedom flexible gun tube model using feedforward and feedback compensation. The first two natural frequencies of the pin-free and cantilever tube are matched by adjusting the dimensions of the rigid segments and the stiffness of the torsional springs that join them. It was found that, contrary to the previously analyzed two degree-of-freedom segment model, the muzzle-end segment could be stabilized by the proper choice of transfer functions and elevation driveline response. The analysis serves to establish the requirements for the transfer functions and stabilizing actuator systems.
