The technical application of puter 3D modeling software, first establish a system of threedimensional solid model of the toy, and then use simulation software to analyze and assess the performance of the toy system, toy design and manufacturing process to achieve a flexible and efficient. The use of this technology not only improves the efficiency of the products also continue to provide ideas for designers to improve the performance of the toys, which makes the design of the research and development costs continue to reduce the more prosperous, but also makes the toy market. In order to adapt to consumer demand, research and development designed to update a wider variety of toy products, virtual prototyping technology for further use. With the development of puter technology and the use of the toy design process is simplified, greatly reducing development costs and design cycle. This topic through the use of UG and Adams kinematics simulation of the dolphin toy, dolphin toy to be demolished, mapping, and then UG software 3D part modeling and assembly, the assembly after its import ADAMS software kinematics simulation and analysis, debugging and parameter settings, the dolphin kinematics simulation. Analyzed and summarized the results of simulation to optimize the design.
