发布时间：2018-12-18 11:17
【摘要】：无论是离心泵的传统方法还是CAD设计方法，离心泵叶轮绘型一直沿用二维工程图（如向视图、剖面图）来表示三维物体。本文采用matlab计算软件，对数值计算直接绘制离心泵叶轮叶片曲面的方法进行探索，旨在研究离心泵叶轮绘型方法。以下为本课题研究所做的主要工作： 1、设计确定离心泵的基本性能参数和基本几何参数，以此作为matlab编程的基础数据； 2、提出采用matlab数值计算直接绘制离心泵叶轮曲面的思路，探索离心泵叶轮参数化绘型方法； 3、通过与传统绘型方法绘制出的叶轮以及与已设计完成的Q7H50离心泵的对比，，获得准确的基础性数据，作为评价离心泵叶轮性能CFD模拟结果的参照； 4、对离心泵水力模型进行全面的CFD模拟分析，分析比较MATLAB方法绘制的叶轮和传统方法绘制的叶轮的精确性、可靠性和实用性； 5、整合并提出更加符合CAD/CAM交会对接的离心泵叶轮绘型方法，使之满足工程实际需要，进一步提升离心泵叶轮绘型水平。 本课题的主要创新点是找到一种新型的、高效的、通用的离心泵叶轮绘型方法，使matlab技术为离心泵叶轮绘型与CAD/CAM对接提供新的思路。 由于时间有限加之本人经验不足，有一些研究内容还有瑕疵。文中的数学模型是建立在一元设计理论基础上的，叶轮叶片进、出口安放角的取值仍旧依赖于设计经验，使得参数化绘型同样对于设计经验具有一定的依赖性。
[Abstract]:Whether it is the traditional method of centrifugal pump or the CAD design method, the drawing of centrifugal pump impeller has always used two-dimensional engineering drawings (such as directional view, profile) to represent three-dimensional objects. In this paper, the method of directly drawing the blade surface of centrifugal pump impeller by numerical calculation is explored with matlab software. The purpose of this paper is to study the drawing method of centrifugal pump impeller. The following is the main work of this research: 1. The basic performance parameters and geometric parameters of centrifugal pump are designed and determined, which is used as the basic data of matlab programming; 2. The idea of drawing the surface of centrifugal pump impeller directly by matlab numerical calculation is put forward, and the parameterized drawing method of centrifugal pump impeller is explored. 3Compared with the traditional drawing method and the designed Q7H50 centrifugal pump, the accurate basic data are obtained, which can be used as the reference for evaluating the performance of the centrifugal pump impeller by CFD simulation. 4. The hydraulic model of centrifugal pump is simulated by CFD, and the accuracy, reliability and practicability of the impeller drawn by MATLAB method and traditional method are analyzed and compared. 5. Integrating and putting forward the drawing method of centrifugal pump impeller, which is more suitable for CAD/CAM rendezvous and docking, so that it can meet the practical engineering needs and further improve the drawing level of centrifugal pump impeller. The main innovation of this paper is to find a new, efficient and universal method for drawing centrifugal pump impeller, so that matlab technology can provide a new idea for the connection between centrifugal pump impeller and CAD/CAM. Due to limited time and my lack of experience, there are some flaws in the research content. The mathematical model in this paper is based on the univariate design theory. The input and outlet angle of impeller blade still depends on the design experience, which makes parametric drawing also dependent on the design experience.
