基于逆向设计的卫生洁具快速制造技术

Backward-design-based technologies for the fast manufacturing of toilet fixtures

以喷射虹吸式坐便器实物为模型,利用激光三维扫描技术对模型的不同位置区域进行测量,采用边缘检测、滤波和曲线、曲面处理建模重构技术,建立3D曲面模型。对此模型进行坐便器冲水过程的三维数值模拟研究,完成坐便器结构的优化设计。最后利用无模铸型制造技术实现喷射虹吸式坐便器的快速制造。研究表明,CAD/CAE/RP等先进的数字化制造技术在卫生洁具研制中应用成功,为复杂陶瓷产品的开发和设计开辟了一条新途径。

In order to optimize the design of toilet fixtures in bathroom,we set up a 3D curve surface model by canning all over a siphon jet toilet fixture model and using techniques of edge detection,filtering,curve and surface reconstruction and studied the corresponding measurements in a simulated test.We found that PCM is the best matrix to manufacture siphon jet toilet fixtures and such technologies as CAD,CAE,RP and so forth are effective techniques to solve the design and manufacture of complicated toilet fixtures.
