Problems solved by technology
[0003] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a cam load mechanism and its algorithm. Aiming at the problems of complex processing and assembly and difficult debugging of a single spring load mechanism when the gradient changes, a combined force-sensing mechanism is adopted. Device: spring plus cam mechanism, which can effectively solve the force gradient change and provide a good sense of control force, and the spring load mechanism adopts a single gradient, which is relatively simple to process and assemble, and the adjustment of force and force gradient is also more convenient

The invention discloses a cam load mechanism and an algorithm of the mechanism. The mechanism comprises a swing rocker arm, a roller bearing, a cam, a load structure support and a spring load mechanism. The top end and the bottom end of the spring load mechanism are in pin shaft connection with the swing rocker arm and the load mechanism support respectively; the cam is mounted on the load mechanism support and is in contact with the roller bearing; and the roller bearing is connected with the swing rocker arm through a standard part. The algorithm of the cam load mechanism comprises the following steps of firstly, drawing a torque-stroke curve; secondly, drawing a thread stand pattern; thirdly, calculating prestress of a spring; fourthly, rotating the cam by a corresponding angle and solving the effective arm force and the spring compression amount; fifthly, determining characteristics of the spring; and sixthly, calculating a torque value under the angle, and judging whether the torque value is qualified or not. According to the cam spring load mechanism and the algorithm of the mechanism, the force sense requirement of a pilot can be better met, and the good social benefits and economic benefits can be obtained.
Description
technical field [0001] The invention relates to the application technical field of a control load mechanism for simulating the formation of an aerodynamic hinge force rectangle of an aircraft control surface, in particular to a cam load mechanism and an algorithm thereof. Background technique [0002] See attached Figure 1~3 , the spring load mechanism is used as the force sensing device. According to different actual needs, it can be designed as a single-spring single-gradient load mechanism, a double-spring double-gradient load mechanism, and a three-spring three-gradient load mechanism. The double-gradient and triple-gradient load mechanisms can realize gradient changes to meet the needs of pilots, but the processing and assembly are more complicated and the force adjustment is difficult. Contents of the invention [0003] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a cam load mechanism and its algori...
