The machining precision in the scroll compressor with the compliant crank mechanism is not required so high as that with the fixed throw crank, but the sealing performance is better than the later's, therefore the scroll compressor with the compliant crank mechanism operates at higher efficiency. In this study, the characters of the compliant crank mechanism are discussed, while the Oldham coup...

Abstract. In the present study, Fourier theory is applied to establish expression of rigid-body poses a spherical four-bar crank slider guidance mechanism. According an analysis harmonic components trajectory curve and rotation angle, it has certain relationship with geometric parameters On this basis, are normalized by preprocessing. Then, angle around y axis z determined, respectively. The th...

In the present work, graphical enumeration technique is applied for structural synthesis of mechanically constrained planar parallel robot formed by single loop 6bar chain or two 3R chains. Two RR chains are added to the considered system to mechanically constraint the movement of its end-effector. Structural code has been proposed as a new systematic methodology to detect isomorphic graphs. Th...

Objective: In this paper, a proposed technique of motion transmission is introduced, which based on the crank-rocker principle motion. The energy action performed through magnetic force, in no direct connection made between source input and load output. Also, to illustrate concept approve continuity using technique, simple model mechanism has been built run, showing basic sequence operation. Me...

The study of insect-inspired flapping robo drones is exciting and ongoing, but creating realistic artificial robots that can effectively mimic insect flight difficult due to the transmission mechanism's need for lightweight minimal connecting components. objective this work was create a system constructing superstructure with fewest feasible links. This one two strokes where fast return mechani...

A partition of a non-negative integer n is a non-increasing sequence of positive integers whose sum is n. For example, The 5 partitions of 4 are 4, 3 + 1, 2 + 2, 2 + 1 + 1, and 1 + 1 + 1 + 1. To explain Ramanujan’s famous three partition congruences, the partition statistics, the rank (resp. the crank) were introduced by Dyson [8] (resp. Andrews and Garvan [3]). Atkin and Garvan [5] initiated t...

This paper investigates the in-hand manipulation capabilities of a compliant, underactuated planar robotic hand by treating the system as a simple, symmetric, 6-bar linkage mechanism with compliant joints. Although underactuated hands are generally not considered to be adept at dexterous tasks, we have found through past work that an underactuated manipulator can control n degrees of freedom wi...

Design optimization of multibody systems is usually established by a direct coupling of multibody system analysis and mathematical programming algorithms. However, a direct coupling is hindered by the transient and computationally complex behavior of many multibody systems. In structural optimization often approximation concepts are used instead to interface numerical analysis and optimization....
