二耦合度9杆巴氏桁架位置分析的超混沌数学规划法
A hyper-chaotic mathematical programming method for displacement analysis of 2-coupling-degree nine-link Barranov truss
摘要
Abstract
A hyper-chaotic mathematical programming method for finding all real solutions of nonlinear equations was proposed and the forward displacement analysis on the 30th 2-coupling-degree nine-link Barranov truss was completed. Four constrained equations were established by using the vector method with the complex number method according to four loops of the mechanism, and four supplement equations were also established by increasing four variables and the relation of sine function and cosine function. The established eight equations are necessary to forward displacement analysis of the mechanism. The hyper-chaotic mathematical programming method was created on the basis of combining the mathematical programming method with hyper-chaotic sequences and utilizing two dimensional discrete hyper-chaotic systems to obtain initial points to find all real solutions of the nonlinear questions. A numerical example of forward displacement analysis was given. The result proves the correctness and validity of the proposed method.关键词
