| Aircraft fly-by-wire joystick system is the front end of aircraft fly-by-wire system, and the reliability of aircraft fly-by-wire joystick system influences the control-stability and security directly. Aim at the reliability enhancement problem of aircraft fly-by-wire joystick system, the redundancy design method based on GO methodology is studied and a new GO analysis design method for aircraft fly-by-wire joystick system reliability is proposed. The GO model and GO operation of aircraft fly-by-wire joystick system with multi-component redundancy parameters are presented. The reliability calculation formula of aircraft fly-by-wire joystick system with multi-component redundancy is derived. The design theory of aircraft fly-by-wire joystick system with high reliability is obtained. A new approach to apply GO methodology to aircraft fly-by-wire joystick system redundancy design is provided. The design example shows that reliability analysis and redundancy design method of the aircraft fly-by-wire joystick system based on GO methodology is accurate and can quickly obtain the optimal redundancy design parameters, which is a feasible method of system analysis and design. |
