Equivalent Variation And Optimization Design Of Brake Pedal Control Mechanism In New Type Combine Harvester

The brake pedal control mechanism of Japan’ s Kubota PRO208harvesters arecharacterized by original conception and smart design. Aimed to practical feature of themechanism, and based on the reverse engineering design method, this paper conducted theanalysis and equivalent variant design to the brake pedal control.Firstly, according to the in-depth understanding of the new harvester brake pedalcontrol mechanism, found that the presence of defects and deficiencies of the steeringmechanism in the production and use. On this basis, design equivalent variation mechanismmodel improved on the original mechanism, then describe in detail the working principle tocomplete the work function of the design equivalent variation mechanism. To establish themathematical model of the mechanism and list in the institutional position of design equationsand constraint equations, provide a theoretical basis for the data optimization.Then, by choosing the appropriate design variables, objective function and constraintsrelated to the preparation optimizer, the local optimal solutions can be obtained， providingdata and theoretical basis for further design.This research comes up with a reliable theoretical support for the harvester-used brakecontrol mechanisms’ analysis and synthesis. As well as the mechanism’s equivalent variantdesign model. Not only it play a guiding role for the follow-up design, but also has somereference value for the new harvester control mechanism equivalent variation or innovationwork.
