基于CAD的滴灌系统水力自动计算模型（Hydraulic Analysis Model in a CAD System for the Design of Drip Irrigation）
滴灌 水力计算 计算机辅助设计
2009/5/22
针对滴灌CAD系统中水力计算与管网布置的耦合问题，研究了管网图形识别及有效性判定，并基于AutoCAD二次开发思想，应用步进法水力学解析原理，建立了滴灌系统计算机辅助设计水力计算模型，有效地将管网图形与水力计算耦合，使水力计算结果及时反馈到管网图形中，为实际工程管网水力性能的优化提供了技术手段。通过算例对该模型进行了验证，结果表明，应用该模型计算出的流量和水头偏差率均在允许范围内，管网识别及水力计...
