基于PMOPSO方法的H型铲齿凸轮优化设计
Optimization design of H-type relieving cam based on PMOPSO method
摘要
Abstract
A standard design approach which is used for the multi-rise H-type cam optimization design is proposed.Aiming at the severe shocking problems of traditional relieving cams during the transient process,the relieving cam design scheme based on motion law of H-type cam followers was proposed.Taking the cam area as the object function and the follower offset and initial displacement as the design variables, H-type relieving cam optimization design model which considered the constrains included the range of theoretical cam surface curvature and the distribution of pressure was proposed based on general design criterions.The optimization problem was featured by multi-constraints, high nonlinear and intensive computation.PMOPSO (polynomial mutation operator particle swarm optimization) method combined polynomial mutation operator and standard PSO method was proposed.By means of PMOPSO method and constraint-handlings of penalty function, the 3-rise and 4-rise H-type relieving cam optimization problems were solved separately.The results showed that the approach was able to decrease the working profile area of multi-rise H-type cam significantly.Meanwhile, the shovel mechanism was more compact.关键词
