摘要

针对高参数转子系统高能量与低振动存在的设计矛盾及耦合问题

提出了一种基于通流力的协同设计方法

并在典型机组上进行了工程验证。采用通流力表征方法构建了协同设计模型

与传统方法建立的模型相比

极大地减少了变量数目以及设计的复杂性和随机性

具有针对性强、设计可信度高的优点。以1 000 MW机组为代表性工程案例

根据转子特征直径和特征转速这两大协同变量进行了协同设计

使原机组高压缸效率得到了提高

同时不仅使临界转速满足设计要求

而且有效地解决了高压转子效率与临界转速之间的设计矛盾。

Abstract

This article puts forward a collaborative method based on flow-passage-force to deal the conflicts and coupling problems between high-energy and low-vibration design of high-parameter rotor system

and verifies the method based on typical engineering units. The collaborative design model was established through the research of flow-passage-force concept and its characterization methods. New model which has advantage of strong pertinence and high reliability reduces the number of variables and the complexity and randomness of design compared with the traditional model. Taking the 1 000 MW unit as typical case and taking rotor characteristic diameter and characteristic rotational speed as core collaborative variables

collaborative design method improves the efficiency of high-pressure cylinder and the critical speed meets requirements. Collaborative design solves the main design contradictions of high-pressure rotor effectively which proves that collaborative design based on flow-passage-force can solve co-design problems of actual units effectively.
