往復式壓縮機之最佳化設計

Abstract

本研究的目的為撰寫一最佳化模組於往復式壓縮機效能模擬軟體。此模擬軟體整合熱流、機構與整體系統動態並以數值方法進行分析與模擬。以此軟體為基礎，本研究發展一最佳化模組，主要包含兩個部份: 使用者介面與最佳化解題工具。使用者介面能幫助快速且方便的規劃與設定不同的最佳化問題，讓使用者或工程師簡單且容易的選擇設計變數、限制條件與目標函數，免除連結分析程式和最佳化程式的困難，並更輕易地處理大量設計變數的最佳化問題。最佳化解題工具則提供方法來解決不同由使用者介面所定義的不同類型的最佳化問題。閥片最佳化設計將是本文中主要探討的議題。此最佳化模組可幫助進行電腦輔助往復式壓縮機的設計，並減少繁瑣且耗時的實驗測試次數，而閥片最佳化的結果將可做為實體壓縮機模型變更設計以改善效能的參考與依據。

The goal of this study is to add an optimization module into one simulation software used in predicting the performance of the reciprocating compressor. This simulation software integrates the analysis of thermal and mechanism modules and simulates by using the computer numerical method. Based on the software program, the study incorporates the optimization module, including user interface and optimization solvers. The user interface can help defining, formulating and setting the optimization problem quickly. With this interface, the user can select design variables, cost function, and constraints freely and conveniently to reduce difficulties in linking between analysis and optimization software. The analysis module in the study is the comprehensive simulation software of the reciprocating compressor. The optimization solvers can contain certain ways providing the user to select. The valve optimization is a main theme for discussion in the study. The optimization module constructed in the simulation software as a useful tool help to aid optimum design of the reciprocating compressor.
