A compliant parallel mechanism for needle intervention
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013This paper presents a compliant mechanism for fine motion of a medical robot for needle intervention procedure. The concept of this mechanism is created with the purpose of correcting a needle axis by translating a main robot for needle driving when an unexpected slip happens in needle insertion.

Analyzing Overconstrained Design of Compliant Mechanisms
Volume 4: 8th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A and B, 2011Whereas the use of compliant mechanisms is favorable for high precision applications, the constraints must be dealt with carefully. In an overconstrained design the actual natural frequencies and stiffnesses can differ considerably from their intended values.

On the Shaking Force Balancing of Compliant Mechanisms
2019 7th International Conference on Control, Mechatronics and Automation (ICCMA), 2019This paper is a first approach in finding design principles for the design of shaking force balanced compliant mechanisms. Shaking force balance means that the motions of the mechanism do not create any resultant dynamic reaction forces on the base, eliminating base vibrations.It is found that for a single balanced rotatable flexible link two stiffness

Topology Synthesis of Large-Displacement Compliant Mechanisms
Volume 1: 25th Design Automation Conference, 1999Abstract This paper describes the use of topology optimization as a synthesis tool for the design of large-displacement compliant mechanisms. An objective function for the synthesis of large-displacement mechanisms is proposed together with a formulation for synthesis of path-generating compliant mechanisms.

Mechanics of compliant structures
2005Biological organisms must be structurally efficient. Hence it is not surprising that nature has embraced the compliant membrane structure as a central element in higher biological forms. This chapter discusses the unique challenges of modeling the mechanical behavior of compliant membrane structures.

Origami-equivalent compliant mechanism
Applied Physics Letters, 2019Origami structures have gained tremendous attention due to their extreme kinematic performance. However, typical origami structures suffer from poor load-bearing capacity due to extreme slenderness of facets. In this letter, we introduce a technique to design an origami-equivalent compliant mechanism which preserves the origami kinetics and kinematics ...

On the Mechanical Advantage of Compliant Mechanisms
How effective are compliant mechanisms for force transmission? We explore here how their inherent elastic deformation limits, or does not, their ability to transmit forces; and analyze their elastokinematic behavior to quantify, understand, and interpret the transmission of forces.R Vishwanath, G.

Compliant transmission mechanisms
2018Classical human-engineered transmission mechanisms such as linkages, gears, and couplings are well established designs which made out of multiple parts and rigid hinges. However, these mechanisms impose disadvantages such as wear, friction, low precision and reliability, need for assembly and lubrications, and difficulty for miniaturization.

Active Compliant Parallel Mechanisms
Volume 5A: 38th Mechanisms and Robotics Conference, 2014In a novel compliant parallel mechanism, a motor and spring are arranged in a parallel fashion and are connected to a movable lever arm. The motor pushes and pulls on one attachment point and the spring stores and releases energy at a second attachment point.

A Compliant Mechanism as a Sternum Prosthesis
2020This paper presents a three-dimensional design of a compliant mechanism as a transmission system for its application in a novel human sternum prosthesis. The proposed compliant mechanism design is able to generate a coordinated movement between ribs during the respiratory process in human beings.
