The invention discloses an optimization method for a medium-high rotating speed cam mechanism, and the method comprises the following steps: obtaining M function constraints according to an expected motion control requirement, and generating a solution set space through the M function constraints; adopting a polynomial linetype and a Fourier linetype to form a segmented curve model, and describing the motion law of a driven part of the cam mechanism through the segmented curve model; according to the solution set space, optimizing the motion law of the cam mechanism follower through an ant colony algorithm; and determining that the ant colony algorithm meets the number of iterations, and outputting an optimal cam mechanism follower motion law. According to the method, a segmented curve composed of a polynomial line type and a Fourier line type is adopted to describe the motion law of the driven part of the cam mechanism, so that the motion law description model has richer curve characteristics and flexibility. In combination with the ant colony algorithm, the solution of the optimization problem is realized, so that the solution process has the advantages of being independent of design experience, high in solution speed, stable in solution effect, parallel in calculation and the like.
Description
technical field [0001] The invention relates to the technical field of mechanical design, in particular to an optimization method for a medium-high speed cam mechanism. Background technique [0002] In the field of mechanical manufacturing, it is a common and basic design requirement to generate periodic motion that meets timing requirements. There are electrical control method and cam mechanism method to produce periodic motion that meets timing requirements. Compared with electrical control method, cam mechanism method has good synchronization and reliability, and low manufacturing cost, so cam mechanism is widely used in machinery manufacturing. High control precision, small peak driving force and long service life are the core demands of cam mechanism design. Therefore, the optimization of the motion law curve of cam mechanism is the basic technology for continuous innovation of machinery manufacturing enterprises. [0003] In the prior art, most general-purpose cam me...
