Dynamic modeling and optimizations of mechanical prosthetic arm by simulation technique

Abstract: Simulation of a mechanical system incorporating the biological control has drawn the fascination of researchers' interest in the research field of advanced prosthetic control and artificial intelligence. This paper generates the idea of modeling of a mechanical prosthetic arm via some heuristic applications of simulation techniques. The introductory part of the paper shows the clinical study of an upper limb amputated patient. Afterwards the experimental approach for measurement of different parameters for the prosthetic arm is described. Then the sets of open loop transfer functions for the study of mechanical prosthetic arm are developed. Optimum transfer functions were initiated in the later part of the paper and finally they are tuned by traditional tuning method as well as the genetic and swarm intelligence tuning algorithms for establishing better results and more efficiency in modeling.

Transient responses of laminated composite plates

Abstract: This article deals with transient responses in terms of displacement and stresses in composite plates. Eight-node isoparametric elements with five degrees of freedom at each node are used to model the plate. First order shear deformation theory (FSDT) with proper shear correction factor is considered to simulate the strain parameters of the plate. The time history responses of the composite plates with both symmetric and anti-symmetric ply layers against different sinusoidal excitation of different excitation frequencies is computed. The effect of different boundary conditions, ply orientation, plan dimension and plate thickness are studied rigorously. Contour plot for normal stress, inplane shear stress and transverse shear stress is plotted for varying ply orientations and boundary conditions for each ply layer. Comparative studies of various stress contours across different layers in a lamina for similar loading or boundary conditions are also presented. A suggestive guideline for design engineers is also provided in terms of stress contour plot for most suitable ply angle and orientation of a composite plate.
