چکیده

Flexible manipulator’s distinct dominance over rigid ones has drawn scientists’ attention increasingly. This type of manipulators is widely used in an extensive range of applications starting from simple pick and place operations to micro surgeries and space manipulators. The deep perception of the dynamic model leads to accurate knowledge of manipulator’s behavior. In the classic approach developed methods are required to solve the complex nonlinear equations which are more tough in closed chain mechanisms. In addition, the equations are much more complicated in flexible structures.A new method of dynamic modeling and simulation of a 2-DOF parallel manipulator with flexible links based on the interface between a finite element modeling software (Abaqus) and a multibody dynamics simulation software (MSC.ADAMS)is proposed in this paper. The CAD modeling and translating the kinematic constraints are presented in detail. Finally the simulation results of the structural model and mathematical model are compared by implementing a full state feedback controller in Matlab/Simulink block diagram. The results demonstrate the method for parallel manipulators with flexible structures is beneficial and practical in industrial applications as well as mathematical nonlinear equations.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
