[Purpose] This study investigated the influence of exercise on balance ability and gait function in stroke patients after applying non-elastic tape, which can stabilize muscles and joints, to the lower extremities of the affected side. [Subjects and Methods] The subjects were 30 patients diagnosed with stroke. They were divided into an experimental group (n = 15) and a control group (n = 15). T...

This paper is concerned with the problem of designing a robust adaptive controller for flexible joint robots (FJR). Under the assumption of weak joint elasticity, FJR is firstly modeled and converted into singular perturbation form. The control law consists of a FAT-based adaptive control strategy and a simple correction term. The first term of the controller is used to stability of the slow dy...

Spring meshes have been used to model elastic material in computer graphics, with skin, textiles, and soft tissue being typical applications. A spring mesh is a system of vertices and edges, possibly with highly irregular geometry, in which each edge is a spring, and springs are connected by \pin-joints" (\gimbal-joints" in 3D) at the vertices. This method is computationally attractive, compare...

The paper presents a methodology to enhance the stiffness analysis of serial and parallel manipulators with passive joints. It directly takes into account the loading influence on the manipulator configuration and, consequently, on its Jacobians and Hessians. The main contributions of this paper are the introduction of a non-linear stiffness model for the manipulators with passive joints, a rel...

To study the laws of evolution dynamic increase factors (DIFs), relationship between DIFs and progressive collapse resisting capacity a structure with web cleat joints under column removal scenario, refined finite element model is established based on an existing quasi-static test. The are studied for different loading type, beam height, joint rotation stiffness. It was observed that displaceme...

Nowadays, mechanical designers and engineers of elastic structures at ultra-small scales face an interesting challenge; traditional flexures with several components, mechanical joints/ welds and linkages are almost impossible to manufacture with existing microsystem fabrica‐ tion technologies. Therefore, the majority of mechanical components, elements and building blocks are based on micro/nano...

Fatigue analysis of aluminum-alloy welded joints based on the linear elastic notch-stress approach is presented in this paper. The International Institute Welding proposes two variants approach, one for thick joints, i.e., with a plate thickness 5 mm or more, reference radius rref = 1 mm, using FAT71 design curve, and thin less than 0.05 FAT180 curve. In work, feasibility proposed S–N curves, o...

This paper presents an algorithm for automatically computing the planar patterns of custom-made assistive medical braces, which are employed to restrict the motion of the joints (such as wrist and knee) that suffer from musculoskeletal disorders caused by repetitive strain injuries. An elastic brace is manufactured by warping a planar elastic fabric pattern. With a specified material, different...

ÐA functionally graded composite is prepared and the spatial gradation of Young's modulus in the functionally graded material (FGM) is measured. Elastic modulus gradients occur over length scales suitable for experimental mechanics investigations using optical interferometry. Crack tip ®elds are mapped in the FGM under quasi-static loading conditions with cracks oriented perpendicular to the di...
