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...

The paper primarily employs the 3D calculation method of helical gear-meshing line and meshing position, in addition to traditional stiffness calculation. This analysis correction load-sharing are beneficial for improving assembly process high-powered critical equipment. dynamic models rigid–flexible coupling, velocity–torque, force planetary gear trains nuclear power plants established based o...

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...

Periodical impulse component is one of typical fault characteristics in vibration signals from rotating machinery. However, this component is very small in the early stage of the fault and masked by various noises such as gear meshing components modulated by shaft frequency, which make it difficult to extract accurately for fault detection. The adaptive line enhancer (ALE) is an effective techn...
