| 中文摘要: |
| 应用MBD技术进行结构复杂产品及大型装配件设计时，由于标注信息量过大易产生“刺猬”现象而影响信息快速准确地
表达和提取。为解决这一问题，提出了简化尺寸标注的MBD 设计方法，通过简化MBD 标注信息能够建立可快速读取的MBD 3维模
型。将新方法应用于某型发动机机匣的设计。研究结果表明：采用简化尺寸标注的MBD方法可大幅减少设计的工作量，提高设计的
效率和质量，验证了该方法的可行性和可靠性 |
| 英文摘要: |
| using MBD (Model Based Definition)technique to design products with complex structure and large assembly parts, the
large amount of annotation information may lead to the"hedgehog" phenomenon, which will impact on the quick and correct expression and
extraction of information. To solve the problem, the MBD design method with simplified dimension annotation was proposed. A MBD 3D
model was built that can be read quickly by simplifying the annotation information of the MBD. The new method was applied to the design
of an engine casing. The results show that the method of MBD with simplified dimension annotation can greatly reduce the design workload
and improve the design efficiency and quality, which verified the feasibility and the reliability of the method. |
