现代机械设计方案 MECHANICAL DESIGN(中文+英文共14000字)
机械产品的方案设计通常无法采用纯数学演算的方法进行，也难以用数学模型进行完整的描述，而需根据产品特征进行形式化的描述，借助于设计专家的知识和经验进行推理和决策。因此，欲实现计算机辅助产品的方案设计，必须解决计算机存储和运用产品设计知识和专家设计决策等有关方面的问题，由此形成基于产品特征知识的设计方法。
目前，智能化设计方法主要是利用三维图形软件和虚拟现实技术进行设计，直观性较好，开发初期用户可以在一定程度上直接参与到设计中，但系统性较差，且零部件的结构、形状、尺寸、位置的合理确定，要求软件具有较高的智能化程度，或者有丰富经验的设计者参与。

THE PROGRAMMES OF MODERN MECHANICAL DESIGN
 The mechanical design of products that is not purely mathematical calculations using the methods, also difficult to use mathematical models to describe the complete, and must be in accordance with product features Formal description help design expert knowledge and experience for reasoning and decision-making. Thus, for the purpose of computer-aided design products, the need to address the use of computer storage and product design knowledge and design experts, and other parties to the decision-making problem, The resulting product characteristics of knowledge-based design methods.

At present, the intelligent design method is to use 3D graphics software and virtual reality technology in design, visualization better, Users can develop early in a certain degree of direct participation in the design, but systemic poor, and parts of the structure, shape, Size, location to determine the reasonable, demand software with high degree of intelligence, or have extensive experience in the designers.
