Virtual prototyping (VP) is a technique in design and manufacture. Dynamic virtual prototype has some key techniques, such as the highest model, real time running architecture and normative data structure. A basic study of dynamics VP was accomplished, and a simple and clear environment of the complex dynamic VP for designing, developing and integrating was submitted. A deep study was thrown into the collaboration simulation environment that based on run time infrastructure (RTI), and a data-gateway was used to deal with high real-time system. The characteristics and key techniques of dynamics VP were summed up.
