Detection Principle

Collision detection is the key technology in the visual simulation system for bridge cranes. According to analyse the collision between hook and virtual objects in visual simulation system for bridge cranes, collision detection method of visual simulation system for bridge cranes is determined based on the collision detection principle. First of all, LOS intersection vector method is chosen based on the principle of collision detection in Vega. Hook is designed for the collision target using Isector module in Lynx and the same intersection vector masks in Isector Class are guaranteed. Then, the BUMP collision detection for hook is created by calling vgIsector functions in VC++ and BUMP detection method of hook is bounded with hook. Finally, conditional statements which ensure hook to move without collision are compiled. Therefore, the virtual scene around the hook is detected in real time. The results show that the phenomenon of passing through by mistake for the hook can be avoided applying the BUMP collision detection method in Vega software in visual simulation system for bridge cranes, and the accuracy for BUMP method detecting the goods is improved using LOS collision detection method.

Abstract It is well-known that so-called Concurrent Engineering is a desirable alternative to the largely sequential methods which tend to dominate most product development methods. However, the proper implementation of a concurrent engineering method is still relatively rare. In order to facilitate the development of a reliable concurrent engineering product development method, we start with a careful definition of concurrent engineering and, after an extensive study of all of product development, we propose three criteria which ideal concurrent engineering must satisfy. However, for labor, time, and overall cost considerations, ideal concurrent engineering is infeasible. Instead, we propose a computer-based environment which, by being constructed in accordance with the three criteria, attempts to approach ideal concurrent engineering. The result is the Virtual Concurrent Engineering method and computer implementation environment. This product development method and computer-based implementation system provide the detailed, structured information and data needed to optimally balance the product with respect to the main product development parameters (e.g., manufacturing costs, assembly, reliability). This important information includes re-design suggestions to improve the existing design. The designer can directly apply these re-design suggestions for design optimization, or he can use the results as input into a more complex design optimization or design parameterization function of his own. To demonstrate Virtual Concurrent Engineering, we use it to refine earlier work done by the authors in the Design for Producibility of stamped products. We discuss, in some detail, the results of applying Design for Producibility to complex stampings, including process plans and product producibility computations.

This paper designed the design scheme of a visual simulation system for tower cranes, and described the methods of modeling scene and manufacturing texture according to the characteristics of Multigen Creator software and Vega virtual software. The five model optimization techniques including levels of detail technique, instancing technique, removing redundant faces, billboard technique and external reference were discussed in the modeling process. In order to improve system running speed, the methods of reducing the face number of the models and save memory spaces were investigated. Scene driving was realized in programming environment of VC++ software. Finally the scene modeling and driving of visual simulation system for tower cranes were completed.

This study extends the new product development (NPD) to a new field; Market Driving Digital New Product Development Method is addressed in this paper, which is based on reverse engineering and rapid prototyping technology. This study finds that the higher the effort on marketing-R&D process, the less possible it might encounter risk. Thus, a better NPD performance can be achieved by market driving Digital NPD method (MDDNPD).A case study of All-Terrain Vehicle (ATV) is used to illustrate the new method. We believe that the proposed methodology will have a positive impact on the future new product development.

A suggestion to School From Home during Covid-19 pandemic made learning process at RA Riyadlotul Uqul, Dusun Lowok, less optimally. Online learning takes place in the form of assignments, and those who haven’t gadgets continue to study at school in turn. The purposes of this service activvity is to develop learning media that is suitbale for the pandemic situation in RA Riyadlotul Uqul. The results of discussions with teachers at that school stated that there were threee suitable media to be developed, animated video, relay stick games, and hand puppets, where all produccts were equipped with user manuals book, so that teacher and parents could easily apply them at home. The product development method adopt ADDIE. The result shows that teacher feels helped by the existance of educational media that is developed, as a variation of teaching techniques, and also build good character for students, which guidebook contains the benefits of using developed media. The teacher, as user, gave suggestions that the video should be uploaded on YouTube, and the guidebook has been copied to make it easier for the teacher to distribute it to the parents of students. The hope is that parents can accompany children to learn while playing at their home.
