【摘要】 在研究计算机辅助设计与现代制造技术的基础上,设计实现了一个基于3D打印技术的工程模型轻量化实验平台,并基于该平台对轻量化设计的相关流程和方法论进行了深入研究。提出使用热扩散模拟受力分布对壳状模型进行轻量化设计,并以3D打印为实验手段,通过构建误差与参数关系对轻量化设计进行验证和反馈修正。实验平台为高效、可信的轻量化问题提供了分析、建模及验证的一整套方法与手段。更多还原

【Abstract】 Based on the research of computer aided design and modern manufacturing,we design and implement a lightweight experimental platform based on 3D printing,and study the processes and methodologies of lightweight on this platform. We use heat diffusion based stress distribution to design the lightweight model,employ 3D printing to produce the entity models for laboratory testing,and achieve the optimal control of lightweight design using parameters feedback. This platform provides an efficient and creditable framework of lightweight consists of analysis,modeling and testing.更多还原
