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.

In recent years, in view of the absence of kinematics analysis function of mechanisms in the virtual assembly system, the method of kinematics analysis of mechanisms based on dynamics of multibody systems in virtual assembly environment is presented. A mechanism is considered as a multibody system and the kinematics equations are established based on Descartes coordinate system. All the kinematics parameters, just like position, speed and acceleration, can be obtained through solving the kinematics equations. In addition, the realization method of mechanism motion simulation in virtual assembly system is also proposed which contains the hiberarchy, data structure, module classes and simulation process of the system. The method is implemented and validated based on the prototype system VAPP(Virtual Assembly Process Planning).

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.

In this paper, a Colored Petri Net modeling method for early stage design of virtual assembly operation is presented. The characteristics of virtual assembly system, Petri Net and Colored Petri Net are analyzed. Some previous work in Petri Net application in assembly and virtual assembly system is discussed. The theoretical aspects of Colored Petri Net are introduced mathematically. Based on the mathematical presentation and the process of fasteners assembly operation, a Colored Petri Net model is constructed for the simulation of assembly operation in virtual environment. With CPN Tools software package, the simulation for evaluating the feasibility of modeling is implemented.

In recent years, under the influence of globalization, more and more different needs have created different sports products. In general, they are mainly used for cardio training and muscular endurance training, and their products for human balance training are few. Balance training has always been one of the most important exercises, but most exercise training is often overlooked. In this study, we searched for sports product patents and related literature that improve balance training and determined the direction of innovative design based on the different patent categories. Based on the results of the analysis, we have redesigned a model that can effectively provide innovative sports products with different angular misalignments and different displacements. In this research, we search, analyze and summarize the related patents and further identify the methods of innovative design to accomplish the required technologies for this design. The relevant design of this study is to use SolidWorks to draw 3D models for motion simulation and size checking. Then use the ANSYS11.0 command module to analyze the body structure of the force situation, to determine the strength and safety. Finally, make the original. Finally, this study hopes to provide a design reference for future sports product design engineers through this design process.
