VE-based assembly modeling and test approach to laser range-finder

The development of Virtual Reality (VR) in engineering has opened up a potent tool to solve assembly and function test problem of product by constructing virtual prototype (VP) in the virtual environment (VE). This paper present a hierarchical assembly modeling approach based on the virtual environment to laser range-finder. The basic idea of virtual prototype is to construct a digital mock-up and test its performance in a virtual environment to replace to make and test physical prototype. An example of product assembly and test is provided to illustrate the effectiveness of the proposed modeling approach. Apply this model approach in author´s own research, has shortened lead time, and improved the product quality.
