Free Form Surfaces

Data acquisition and model reconstruction of free-form surfaces with holes were been studied, based on coordinate measuring machines. First, the structural process of the parts was analyzed, the method of combinate contact measurement with non-contact measurement were used to get point cloud; Then the point cloud were been preprocessed, feature curve extracted and solid modeled; Finally, the restructure model was been quality assessed and accuracy assessed. Using the measurement of combinated contact and non-contact can also meet both the precision requirement of key part and the fast reconstruction requirement of non-critical part, which has great significance on that part to fast and accurate reconstruction.

AbstractThe main goal of the article is to describe the development and production of a prototype of an additional system for wheel motor bearing protection using additive technologies. These technologies include rapid prototyping and vacuum casting. These technologies greatly facilitate and speed up the whole process of developing a new component. Before the development itself, it was necessary to digitize the wheel hub using reverse engineering technology. Using a 3D scanner, a part model was created, based on which an additional system for wheel bearing protection was designed for the CAD system. The dimensional analysis of the produced prototypes was performed. Prototypes of the protection system made of different materials will be tested in common operation conditions.

Track Slab

The dimension detection of high-speed railway track slabs is one of the most important tasks before the track slabs delivery. Based on the characteristics of a 3D scanner which can acquire a large amount of measurement data continuously and rapidly in a short time, this paper uses the integration of 3D scanner and the intelligent robot to detect the CRTSIII (China Railway Track System) track slab supporting block plane, then the dense and accurate supporting block plane point cloud data is obtained, and the point cloud data is registered with the established model. An improved Random Sample Consensus (RANSAC) plane fitting algorithm is also proposed to extract the data of supporting block plane point cloud in this paper. The detection method is verified and the quality analysis of the detection results is assessed by a lot of real point cloud data obtained on site. The results show that the method can meet the quality control of CRTSIII finished track slab and the detection standard. Compared with the traditional detection methods, the detection method proposed in this paper can complete the detection of a track slab in 7 min, which greatly improves the detection efficiency, and has better reliability. The method has wide application prospects in the field of railway component detection.

For the problem that power circulation and low efficiency easily occur in closed Continuously Variable Transmission (CVT), the input-coupled CVT drive system was taken as the object of study, the fundamental structure and working principle of the input-coupled CVT drive system were briefly introduced. In the circumstances of no energy loss, the sufficient condition for the input-coupled CVT drive system to realize power split was deduced in detail. Next, the meshing efficiency expression for the 2K-H type differential gear train was simplified under the sufficient condition. The condition for maximizing the meshing efficiency of the 2K-H type differential gear train was demonstrated. Finally, the conclusion was verified by example. The results show that the condition of maximum meshing efficiency ensures the highest meshing efficiency of the 2K-H type differential gear train from the design point of view.

The complex surface is modeled by triangular surface, B-spline or non-uniform rational B-spline first and then the planing of the cutter is followed in reverse engineering. But this require CAD/CAM software and operator’s experiene. Because of this，the research on direct NC cutter generation from point cloud have become the focus of research in reverse engineering. The normal，curvature，surface vary et al parameters are calculated by principle component analysis method and so on, which define the local feature of the surface hidden in the point cloud. Then，based on local feature，point cloud is simplified. It is proved that two points with minimal orientation-distance on a pair of smooth surfaces are conjugate points. Thus the conjugate problem between the tool surface and the part surface is converted into optimization process of orientation-distance function. The cutter trace and the cutter interference are achieved by local and global optization of the orientation-distance function.
