Dynamic Behavior Analysis of a Planar Four-bar Linkage with Multiple Clearances Joint
In practice, clearances in the joints are inevitable due to tolerances, and defects arising from design and manufacturing. In the presence of clearance at a joint, a mechanism gains some additional, uncontrollable degrees of freedom which are the source of error. Moreover, joints undergo wear and backlashes and so cannot be used in precision mechanisms. In this study, the dynamic behaviour of ...
متن کاملThe Optimization Design of Six-bar Linkage Mechanism
At present, multi-bar linkage mechanism is one of the most important directions of mechanical presses’ development. Utilizing the typical multi-linkage drawing mechanism of the plunger slide and compounding its parameters scientifically are a fairly effective way to realize the drawing technology demand. This paper established kinematics mode of the six-bar drawing mechanism by bar-group method...
متن کاملConventional 4-bar linkage knee mechanisms: a strength-weakness analysis.
The purpose of this article is to inform clinicians of the relevant knowledge gained from research in the field of prosthetics. From a biomechanical point of view, clinicians need relevant knowledge in order to properly prescribe a lower limb prosthesis, including prosthetic components. In this context, and due to the lack of data regarding their utility, a strength-weakness analysis of 8 types...
متن کاملA new modular six-bar linkage trans-femoral prosthesis for walking and squatting.
Four-bar linkage mechanisms produced by many designers of knee joints for trans-femoral prostheses can provide knee rotation to permit walking only. In Afro-Asian countries people are accustomed to a squatting posture in their daily activities. A six-bar linkage knee-ankle mechanism trans-femoral prosthesis is described which was developed and fitted to an amputee. The motion patterns of the an...
متن کاملAnalysis of an Underactuated Compliant Five-bar Linkage
Deepak Behera and Dr.J.Srinivas, Department of Mechanical Engineering, NIT-Rourkela 769 008 email: [email protected] Abstract: This paper presents the kinetostatic analysis and design of a two degree-offreedom five-bar underactuated compliant mechanism using a pseudo-rigid body modeling. Two of the joints in the linkage are flexible and actuation is provided to the crank. The slider connected ...
