摘要
近年来，虚拟样机技术已广泛应用于各个设计制造行业，在玩具设计制造业中同样应用广泛。该技术首先应用计算机三维建模软件，建立玩具系统的三维实体模型，然后利用仿真软件进行分析和评估玩具系统的各项性能，使玩具的设计制造过程实现了柔性化和高效化。这项技术的运用不仅提高了产品的生产效率，还不断为设计者们提供思路改善玩具的各项性能，从而使得研究开发的设计成本不断降低，同时也使得玩具市场更加繁荣。为了适应消费者的需求，研发设计出更新更多种类的玩具产品，虚拟样机技术得到了进一步的运用。随着计算机技术的发展和运用，整个玩具的设计过程不断简化，大大减少了开发成本和设计周期。
本课题通过运用UG和Adams对玩具海豚进行运动学的仿真。首先，对海豚玩具进行拆卸、测绘，然后在UG软件中进行三维零件建模并装配，装配完后将其导入ADAMS软件中进行运动学的仿真和分析，通过不断的调试和参数的设定，实现了玩具海豚的运动学仿真。最后，对仿真的结果进行分析和总结，优化设计方案。

Abstract
In recent years, virtual prototyping technology has been widely applied to various design manufacturing industry, also widely used in the manufacturing of toy design. The technical application of computer 3D modeling software, first establish a system of three-dimensional 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 computer 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.
Keywords：virtual-prototyping，three-dimensional，simulation ，model debuging，kinematics
