Abstract This paper presents a novel approach to accurately simulate the dynamic characteristics of rack and pinion lifting mechanism while accounting for coupling effect meshing tooth pair stiffness grease in real-world environments. A structure-grease model is established based on deformation coordination conditions meshing. The incorporates term time-varying pinion. By analyzing combined com...

The nite element method is being used today to model component assemblies in a wide variety of application areas, including structural mechanics, uid simulations, and others. Generating hexahedral meshes for these assemblies usually requires the use of geometry decomposition, with di erent meshing algorithms applied to di erent regions. While the primary motivation for this approach remains the...

Meshing tools are extremely complex pieces of software. Traditionally, they have been built in a one by one basis, without systematically reusing already developed parts. The area has matured so that we can currently think of building meshing tools in a more industrial manner. Software product lines is a trend in software development that promotes systematic reuse. We propose a layered product ...

Isometric modification is proposed as a new method of axial modification of spur bevel gear. Based on the gear geometry theory and the normal meshing motion equation of gear pairs, changes of meshing points and angles are analyzed and the effect of axial modification on meshing movement of gear pairs is discussed. After that, a method of drawing spherical involute with the aid of SolidWorks sof...

A mesh is said to be dendritic if it contains elements with mid-side (edge) nodes when the predominant element topology has only corner nodes. A dendritic mesh is illustrated in Figure 1 where the predominant element is a four-node quadrilateral, but has also several five-node quadrilateral elements each with one mid-edge node plus four corner nodes. Such meshes arise when an approximately unif...

In this study, a numerical simulation method was employed to investigate and analyze superstructure fiber Bragg gratings (SFBGs) with five duty cycles (50%, 33.33%, 14.28%, 12.5%, and 10%). This study focuses on demonstrating the relevance between design period and spectral characteristics of SFBGs (in the form of graphics) for SFBGs of all duty cycles. Compared with complicated and hard-to-lea...

some numerical and experimental investigations are made on the performance of five different hyperelastic constitutive models (second order polynomial, yeoh, arruda-boyce, ogden and marlow) in tension and compressionmodes. first, the results of the tensile and compression tests on a rubber sample were used to determine the parameters of the models by curve fitting methods. next, by using an alg...

A unified topological layer for mesh generation has been created to benefit from current development, to reuse existing, well tested and reliable methods, such as the Delaunay or the Advancing Front mesh generation approach, and to combine them to be able to interchange these methods, without taking a detour using file formats. In addition, by modularizing existing meshing kernels, this approac...

In an effort to improve the robustness and efficiency of mesh adaptation, this work proposes an adaptive re-meshing method that can be used for variety of problems in CFD. It should be noted that this method is feature driven adaptivity and that it does not use strategies such as edge split, edge collapse, edge swap, etc as were employed in mesh modifications [2]. Instead, it defines the ”holes...
