In this study, a 42-degree-of-freedom (42-DOF) translation–torsion coupling dynamic model of the wind turbine’s compound gear transmission system considering time-varying meshing friction, stiffness, damping, error and backlash is proposed. Considering different between internal external teeth planetary gear, stiffness calculated by using cantilever beam theory. An improved friction takes into ...

DStrips is a simple and efficient method to dynamically manage and generate triangle strips for real-time viewdependent multiresolution meshing and rendering. Progressive view-dependent triangle mesh simplification and rendering is an important concept for interactive visualization environments. To minimize the rendering cost, triangle meshes are simplified to the maximal tolerated perceptual e...

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. We propose a layered product line architecture for meshing tools that can be instantiated with different algorithms, wa...

A single screw compressor is an important element found in many refrigeration systems. A single screw compressor with column envelope meshing pair will have long operating life than existing single screw compressors, although it is still fail to meet industrial applications. To accelerate the industrial application of the new type compressor, a design method of column envelope meshing pair is p...

A novel method is presented for automatically generating quadrilateral meshes on arbitrary two-dimensional domains. Global minimization of a potential function governs mesh formation and characteristics. Comprised of several terms, the potential function distributes the elements throughout the domain and aligns the edges of the elements to form valid connectivities. If there are any remaining u...

We are concerned with Delaunay mesh generation methods and mesh adaptivity issues Planar surface and volume meshing have been automated to a large extent Over the last few years meshing activities have been focused on adap tive schemes where the features of a solution eld must be accurately captured To this end meshing techniques must be revisited in order to be capable of complet ing high qual...

The transform relation between the meshing position and rotation angle of a cylindrical gear pair is firstly derived according to the theory of gear meshing. Then the technique of building the assembly model of a cylindrical gear pair at specified meshing position in ANSYS is researched. On this basis, a new method to perform static contact analysis of cylindrical gear at any meshing location i...
