基于染色体模型的机构仿生变异设计

Chromosome model based bionics variant design of mechanism

分析了在运动输入不变的前提下控制机构运动输出的影响因子,借鉴遗传学中的若干概念和原理,将这些影响因子分别表达为运动副染色体序号、运动副特性基因和距离关系矢量基因,并对其进行编码,建立了由机构染色体关系图和机构染色体矩阵组成的机构染色体模型,借鉴遗传学减数分裂和染色体变异等原理提出了三种对机构染色体模型的运动副染色体基因重组运算——显性、易位和转移。利用该设计方法由牛头刨床原机构获得变异机构,证明了该方法的简便性和实用性。

The Influencing factors which controlled mechanism motion output were analyzed on the premise of constant motion input.They were represented as kinematic pair chromosome number,kinematic pair feature gene and distance relationship vector gene respectively by borrowing several concepts and principles in genetics,and they were encoded at the same time.Mechanism chromosome model was established which was composed of mechanism chromosome relationship graph and mechanism chromosome matrix.Three kinematic pair chromosome gene recombination operations（dominance,translocation and metastasis） on mechanism chromosome model were proposed by using meiosis and chromosome variance in genetics for reference.Variant mechanism was acquired based on shaper original mechanism by using this method,and its practicality was demonstrated as well.
