Portal Crane

Portal Crane with its large parts is inconvenient to achieve physical prototype assembly in design process because of its large span and high precision space assembly needs. Considering virtual assembly system can provide designers with specific modules library, person interactive experience and reliable assembly simulation, this paper modularized the MQ4025 Portal crane based on analysis of assembly needs, and accomplished corresponding modules modeling by Solidworks, developed a virtual assembly platform by Virtools, realized collision simulation between components and parts by Collision Detection Building Blocks in Virtools, performed a virtual assembly experiment on the platform. Result shows that the platform completes Portal Crane assembly in a shorter time than physical prototype assembly, and it completes the assembly simulation faster than other CAD software by invoking compositive modules library of Portal crane.

Important Research Topic

In recent years, physical simulation is a new trend of virtual assembly (VA) technology. As a part of physical simulation, mechanisms motion simulation is an important research topic. In order to realize the mechanisms motion simulation in VA system, we presented the realization and application method of mechanisms motion simulation in virtual assembly system combining the prototype system, Virtual Assembly Process Planning (VAPP). We described the bottom framework of VAPP system used for mechanisms motion simulation. Then based on the support of bottom platform, we studied the realization method of mechanisms motion simulation and apply mechanisms motion simulation to virtual assembly simulation via some technologies in VAPP system. Our research shows that, simulating mechanisms motion in VA system not only realizes the visualization of mechanism analysis and simulation, but also improves the ability of analysis of VA system effectively and extends the application range of VA system.

Visual Basic 6.0

On the basis of analyzing assembly process of main structural components in CA6140 lathe, 3D models for those components were established with CAD software UGNX6.0. Virtual assembly and motion simulation of the structure parts were performed with virtual technology. A set of virtual assembly system of CA6140 engine lathe was developed with programming software Visual Basic 6.0. It contains six main modules about spindle box, feed box, apron, tailstock, turret, etc. Dynamic simulation and motion simulation of the corresponding components in entity lathe can be realized, respectively. And also, mechanical structure, working principle, assembly relation between different components and motion transmission process of the lathe can be realistically reproduced with the system. This virtual assembly system not only can be used to analyze and transform old products, but also can be used in new products development, and to some extent, can be used to replace the prototype. It is an indispensable tool in the employee training and mechanical engineering activities.

Abstract 3D collision detection and modeling techniques can be used in the development of haptic rendering schemes which can be used, for example, in surgical training, virtual assembly, or games. Based on a fast collision detection algorithm (RAPID) and 3D object representation, a practical haptic rendering system has been developed. A sub-system determines detailed collision information. Simulation results are presented to demonstrate the practicality of our results.
