The present work aims to evolve the multiple topologies of path generating compliant mechanisms. The trade-off solution’s based topologies are developed by simultaneously minimization of weight and supplied input energy to elastic structures. The functional aspect of these compliant mechanisms is accomplished by imposing the constraints on precision points to generate the user-defined path. The...

Abstract—This paper presents a design and optimization for a compliant gripper. The gripper is constructed based on the concept of compliant mechanism with flexure hinge. A passive force regulation mechanism is presented to control the grasping force a micro-sized object instead of using a sensor force. The force regulation mechanism is designed using the planar springs. The gripper is expected...

In this paper, an improved initial random population strategy using a binary (0-1) representation of continuum structures is developed for evolving the topologies of path generating complaint mechanism. It helps the evolutionary optimization procedure to start with the structures which are free from impracticalities such as ’checker-board’ pattern and disconnected ’floating’ material. For gener...

Based on the constraint and position identification (CPI) approach for synthesizing XYZ compliant parallel mechanisms (CPMs) and configuration modifications, this paper proposes a new fully-symmetrical XYZ CPM with desired motion characteristics such as reduced cross-axis coupling, minimized lost motion, and relatively small parasitic motion. The good motion characteristics arise from not only ...

The present work focuses on evolving the multiple light-in-weight topologies of compliant mechanism tracing user defined path. Therefore in this paper, the bi-objective set is formulated first on the optimization frame-work in which the helper objective of maximum diversity is introduced with the primary objective of minimum weight of elastic structures. Thereafter, the evolutionary algorithm (...

BACKGROUND The current generation of total disc replacements achieves excellent short- and medium-term results by focusing on restoring the quantity of motion. Recent studies indicate that additional concerns (helical axes of motion, segmental torque-rotation behavior) may have important implications in the health of adjacent segments as well as the health of the surrounding tissue of the opera...

The rotator type of optical modulating component modulator requires a planar angular rotator to control different angles for modulating the dissimilar light. If simply using the S-shape beam to behave a pin-joint, the rotator angle will be limited. The design target accordingly needs to maximize the range of output angle for satisfying the prescribed linear output positions or can be a sort of ...

Compliant Mechanism has been designed for various types of application to transmit desired force and motion. In this study, we have explored an application of Compliant Mechanism for passive vibration isolation systems, for which compliant isolator is used to cancel undesired disturbance, which results in attenuated output amplitude. The Compliant Mechanism is equipped with isolator, which acts...

In traditional rear trunk lid designs, extra devices (e.g., hydraulic actuators and spring mechanisms) are employed to compensate the lid weight and reduce the efforts for both opening and closing it. Such devices often consist of a number of parts, thus leading to high costs for manufacture, assembly and maintenance. In this paper, we designed a compliant bistable mechanism to keep the lid’s t...
