Dynamic properties

In kinematic synthesis and analysis of planar mechanisms the designer must define a geometry and set of motions for a design task. This paper will focus on how to determine the forces or torques acting on the planar mechanism by numerical method when acceleration and dynamic properties of the linkage are known.

The dynamic analysis is a necessity in the design, manufacturing and maintenance of structures. The analytic solutions are not available for most practical cases and the Finite Element Method (FEM) is not reliable due to the joint problem, unclear loading, material properties and numerical error. In this paper, we present a way to find modes shape of 3D Frame by FEM program using Matlab.

To achieve the aim, the first objective is preliminary experiments on preparation of polypropylene blends with silicone elastomer masterbatch and characterize by analysis of mass composition, mechanical properties, and dynamic mechanical properties to investigate any improvement of properties. The silicone elastomer masterbatch will then be substituted with propylene-maleic anhydride graft copolymer waxes or other compatibilizers.

The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory.

: Fluid vents in the Sea of Marmara were discovered and investigated by several studies. In this paper, a numerical model is created for the first time to determine the possible transport mechanism behind those fluid emissions at the seafloor. The finite volume method is used for numerical simulations by implementing a commercial finite volume code, ANSYS-Fluent. The thermal and physical rock properties used in our models are taken from previous studies.

At a temperature of 300 K, both Ni and Cu atoms are crystallized into the face-centered cubic (FCC) and the hexagonal close-packed (HCP) phases, respectively. The mechanical characteristics of the sample at 300 K were also analyzed in detail through the determination of elastic modulus, number of atoms, and void distribution during the tensile process.

Some thermodynamic quantities of ZrxCe1-xO2/CeO2 systems are investigated by using the moment method in statistical dynamics taking into account the anharmonicity effects of lattice vibrations. The analytic expression of the Gibbs free energy, Helmholtz free energy, and specific heats at the constant volume of ZrxCe1-xO2/CeO2 systems are obtained.

The additional network-modifying cation oxide breaking up this network by the generation of nonbridging O atoms and it has a slight effect on the topology of SiOx and OSiy units. Moreover, the diffusion of network- former atom in sodium-silicate melt is anomaly and diffusion coefficient for sodium atom is much larger than for oxygen or silicon atom. The simulation proves two diffusion mechanisms of the network-former atoms and modifier atoms.
