Reconfiguration of a four-bar mechanism using phase space connections
Linkage mechanisms are perhaps the simplest mechanical structures in engineering, but they can exhibit significant nonlinearity which can in principle be exploited. In this paper a simple smart structure model is developed based on such nonlinearity to investigate the reconfiguration of a four-bar mechanism through phase space connections. The central idea is based on heteroclinic connections i...
متن کاملNonlinear dynamic analysis of a four-bar mechanism having revolute joint with clearance
In general, joints are assumed without clearance in the dynamic analysis of multi-body echanical systems. When joint clearance is considered, the mechanism obtains two uncontrollable degrees of freedom and hence the dynamic response considerably changes. The joints’ clearances are the main sources of vibrations and noise due to the impact of the coupling parts in the joints. Therefore, the syst...
متن کاملDimensional Synthesis of Four Bar Mechanism Using Genetic Algorithm
The dimensional synthesis is done by using Genetic Algorithm to achieve a desired trajectory. Three problems are analyzed having different curvature. The program is authored in MATLAB ® 2010a. The error is seen to be in the permissible prescribed limit. The prototyping of straight line trajectory analysis is also done in ADAMS ® .
متن کاملOn the Synthesis of a Reactionless 6-dof Parallel Mechanism Using Planar Four-bar Linkages
This paper addresses the synthesis of a novel reactionless spatial 6-DOF parallel mechanism using four-bar linkages without any counter-rotations. The mechanism is first described and its kinematics is discussed. A numerical example of the reactionless 6-DOF mechanism is given in this paper and, with the help of the dynamic simulation software ADAMS, it is shown that the mechanism is reactionle...
متن کاملOptimum synthesis of a four-bar mechanism using the modified bacterial foraging algorithm
This paper presents the mechanical synthesis of a four-bar mechanism, its definition as a constrained optimization problem in presence of one dynamic constraint and its solution with a swarm intelligence algorithm based on the bacteria foraging process. The algorithm is adapted to solve the optimization problem by adding a suitable constraint-handling technique able to incorporate a selection c...
