Abstract

The invention discloses a method for optimizing general parameters of a control surface transmission mechanism. The method comprises the following steps that analytical expressions of the line rigidity, torsional rigidity, torsion frequency, the steering engine actuator travel original length ratio and the transmission ratio deviation of the control surface transmission mechanism are established; a parameterized ADAMS model of the control surface transmission mechanism is established; the ADAMS model, an input file including input variables, an output file including measurement values and a command file for driving an ADAMS are packaged; optimization goals and constraint conditions are determined; a ModelCenter optimizer and the ADAMS model are used for optimizing the designed distance between a variable rudder shaft and a steering engine support, the length of a rocker arm and the height of the steering engine support with the determined optimization goals and the constraint conditions, and optimized results are obtained. By means of the method, the quick optimization design of the general parameters of the control surface transmission mechanism is achieved, and engineering technicians can conveniently use the method.

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 ...
