Disclosed herein is a multi-mesh gear system, such as an epicyclic gear system, in which (a) optimal performance is not load-specific and (b) the same profile modifications can be applied on both flanks of the common gear. This is accomplished through a novel combination of a constant system contact ratio and gearing having mesh stiffness variation reducing, or MSVR, modifications. An MSVR modification, such as Differential Crowning, will minimize the self-excited component of dynamic load for gear meshes across different operating loads, resulting in an optimized gearset. The specification of a substantially constant contact ratio for the multi-mesh gear system allows the same MSVR modification to be used on both tooth flanks of the common gear, reducing the cost and complexity of manufacture.

The invention provides a fast Delaunay triangulation method for arbitrarily-distributed large-scale point cloud data, comprising the following steps: dividing a multi-grid to create an initial triangulated network; inserting points one by one; updating the triangulated network; and deleting auxiliary triangles to complete Delaunay triangulation. Through multi-grid division and a sorting method through sequential grid traversing based on a Hilbert curve, the search step length in the point positioning process and the number of finally-deleted long-narrow triangles produced in the triangulation process are reduced. By adopting a new algorithm in the point positioning process, the process of solving the centers of gravity and intersecting edges of triangles is avoided, and the amount of calculation is reduced. The efficiency of Delaunay triangulation under the condition of a large amount of point cloud data and uneven distribution thereof is improved greatly.
