A GPGPU-based collision detection algorithm is proposed. Firstly, the information of OBB hierarchy tree and triangles of tested objects are mapped into some data textures designed for GPGPU-based calculation, such as triangle vertex textures, bounding box size texture, tree node relationship texture, etc., then these textures are downloaded to GPU to(More)
VR-based technology is a feasible idea for remote distance operation. Aiming the present material handling machine status, which is widely used in mine, port, train station, etc al, in this paper, the scheme of IR-based material handling remote operating for engineering machine (VMHROEM) is presented. The frame of this system is build, and simulating theory(More)
1.1 Railway vehicle virtual prototyping In recent years, knowledge-based new product competition has become the mainstream of manufacturing competitiveness. As an important way to simulate various problems of complex mechanical systems, virtual prototyping technology is being widely used. It supports concurrent engineering and emphasizes the overall product(More)
This paper presents a comprehensive surface waviness control technology for 5-axis flank milling. Through constructing dual NURBS curves to describe toolpath, the feedrate and rotary axis optimization method is proposed. Through controlling milling area rate, the proposed method could improve the 5-axis flank milling state under the constrains of cutting(More)
