摘　　要：针对可调机构的刚体导引综合问题,提出了基于进化计算的可实现多个任务的机构综合方法。建立了多任务机构优化模型,采用进化计算进行优化,容易得到全局最优解。文中对进化计算进行了改进,提出了一种根据个体适应度自适应调节变异率和变异量的方法,能有效提高进化速度和求解精度。两个数字实例阐述了这一方法。The method of rigid-body guidance synthesis of adjustable mechanisms for multiple alternation tasks based on evolutionary computation is proposed.The mechanism optimization model of multi-tasks is established,and the global optimization solution will be gained easily by using evolutionary computation.The algorithm of evolutionary computation is improved.A method that can adaptively adjust mutation rate and mutation value according to fitness of individual is proposed,which can effectively improve the evolutionary speed and the accuracy of the solutions.Two numeric examples are given to illustrate the method.
