基于快速成形技术(RP)的滴灌滴头开发可省去传统开发路线中的模具制造环节，从而可大大缩短新型滴头的开发周期，降低开发成本，本文旨在实现滴头参数化结构设计，构建滴头快速开发平台技术，为实现我国自主快速开发节水灌溉产品提供依据。 文中以参数化的设计思想，通过改变梯形迷宫流道单元尺寸和单元数设计了8种梯形迷宫流道，采用快速成形技术制作出外管与内迷宫流道一体化的滴头原型；利用最小标注尺寸为50nm的光学显微系统对滴头流道结构尺寸进行了测量，分析结果显示流道尺寸精度完全满足滴头的制作要求。制作出的一体化滴头原型直接连接到水力性能试验台上进行流量试验，测定了12个压力点下8种滴头原型的出水量；应用MATLAB软件中的多元线性回归算法对所得试验数据进行了回归分析，得出了8种滴头的压力流量公式和回归曲线图。 试验结果分析表明，流道单元数越多或单元尺寸越小，压力流量曲线越平缓，即水力性能越优越。通过修改流道单元尺寸和增减流道单元数可设计出多种流量随压力缓变的大流量优质滴头，为实现滴头参数化结构设计提供了依据。总结出以梯形单元为模块的水头损失公式，为研究其它迷宫滴头的消能机理提供了有效方法；通过试验验证了回归公式的可行性和准确性。 采用Fluent流体分析软件对迷宫流道内的水流流态进行了计算和仿真，解决了长期以来迷宫流道流态的黑匣子问题，为滴头的防堵结构设计提供了理论依据。8种迷宫滴头的仿真结果显示滴头流道内的流态整体比较理想，但在尖角处存在低速区。把尖角分别设计成不同半径的圆弧后发现，流道流态得到了不同程度的改善，从而提高了滴头的抗堵能力。

Rapid development of water-saving emitter based on rapid prototyping technique can eliminate the necessity of mould making, and accordingly reduce the developing cycle and cost of new emitters. The purpose of this thesis is to realize parameterized structural design of emitter，and lay a preliminary foundation for rapid development of our own sinicized emitters. Eight trapezoid labyrinth flow-channels are designed through modification to the cell dimension and the number of flow cells based on the parameterized structural design. Integral emitter prototypes combining exterior hull and exterior flow-channel are built using rapid prototyping technique, and structural dimension of those flow-channel are measured by optical microscope, the measuring results showed that the design can completely meet the requirement of emitter accuracy. The labyrinth-type emitter can be directly applied to irrigation experiment, the flow rate of 8 emitter prototypes are mensurated under 12 pressure values on the test-bad. Moreover, experimental data are analyzed with multivariable linear regression in MATLAB, formulas of pressure versus flow and regression plots for 8 different emitters are induced from the regression analyses. The conclusion that the more the number of labyrinth is or the smaller the cells are, the more gentle the slope of the plot has been arrived at from the 8 formulas and regression plots. So emitters of high quality can be produced by modification to the cell dimension and the number of flow cells, which provides efficient method for designing parameterized structure of emitters. Furthermore formulas of pressure loss are summarized based on trapezoid cell, this approach may be applied to study the mechanism of dissipative energy in other labyrinth emitters, and those regression formulas are tested through experiments. Flow behaviors of 8 emitters are analyzed by FLUENT, flow channels show good fluidness, but lower flow rate is found in exterior corners of the emitter channel. When exterior corners are designed with circular arcs, the flow behavior is improved to some extend. So Emitter with good fluidness and anti-clogging are developed by the above methods.
