Description

technical field [0001] The invention relates to an overall parameter optimization method of a rudder surface transmission mechanism, which belongs to the field of mechanism design. Background technique [0002] The rudder surface transmission mechanism is a mechanical transmission device connecting the aircraft rudder surface and the servo actuator. With the new type of aircraft, the technical requirements of light weight, small size, high rigidity and long life are put forward for the rudder surface transmission mechanism. Among them, the stiffness of the rudder surface transmission mechanism directly affects the transmission accuracy and control accuracy of the rudder system, and is the most important technical index of the rudder surface transmission mechanism. The static stiffness of the rudder mechanism is the ability of the rudder mechanism to resist deformation under the working static load, which is usually measured by the linear stiffness or torsional stiffness of ...
