Nonlinear 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 کاملDevelopment of expert system for four Bar Mechanism
In this study, an expert system was developed for a quadricycle four bar mechanism with control of transmission angle. Different types of available synthesis methods are studied and the suitable synthesis procedure is selected for developing the expert system.
متن کاملDifferential Evolution for the Control Gain's Optimal Tuning of a Four-bar Mechanism
In this paper the variation of the velocity error of a four-bar mechanism with spring and damping forces is reduced by solving a dynamic optimization problem using a differential evolution algorithm with a constraint handling mechanism. The optimal design of the velocity control for the mechanism is formulated as a dynamic optimization problem. Moreover, in order to compare the results of the d...
متن کاملCrossed four-bar mechanism for improved prosthetic grasp.
Passive linkages were developed to improve grasp functionality and minimize a prosthetic terminal device's number of user-controlled inputs. The linkages act to stabilize grasped objects and substitute for the palp of normal anatomical fingers. The Southampton Hand Assessment Procedure was used to compare the normal anatomical hand, this prototype, and a commercially available (Hosmer) hook. In...
متن کاملStudy on Optimization for Four Bar-Partially Compliant Mechanism
This paper concentrates on the application of fuzzy logic based on Taguchi method (FLTM) for multiobjective optimization of the small-length flexural pivot (belongs to link 4) in partially four bar-compliant mechanisms. The input parameters such as the input torque and the crank angle of link 2 were optimized with considerations of the multiple performance measures as angular displacement and s...
