【摘要】:項目教學是一種以問題為導向的教學模式,而教學項目設計是項目教學的一個關鍵環(huán)節(jié)。針對《機械優(yōu)化設計》課程特點及教學中存在的問題,以提高學生對理論知識的運用能力為目標,選取一個帶傳動和鏈傳動兩級傳動的優(yōu)化設計為教學項目,建立了優(yōu)化設計的數(shù)學模型,包括目標函數(shù)、約束條件等。應用Excel軟件,按照圖表數(shù)據(jù)化、模型實現(xiàn)和解算等步驟實現(xiàn)對優(yōu)化設計模型的求解。該軟件對解決優(yōu)化設計問題具有建模過程簡單、優(yōu)化設計計算速度快、設計資料可讀性高、設計自動化水平高等優(yōu)點,可以大大提高設計人員的設計效率,為優(yōu)化設計的工程應用提供了新的借鑒思路。該教學項目"教、學、做"相結合,突出學生應用能力的培養(yǎng),提高了學生學習興趣和解決實際問題的能力。
[Abstract]:Project teaching is a problem-oriented teaching mode, and teaching project design is a key link of project teaching. In view of the characteristics of the course "Mechanical Optimization Design" and the problems existing in teaching, aiming at improving the students' ability to apply theoretical knowledge, an optimal design of belt transmission and chain drive two-level transmission is selected as the teaching project. The mathematical model of optimal design is established, including objective function, constraint condition and so on. Excel software is used to solve the optimal design model according to the steps of chart data, model realization and calculation. The software has the advantages of simple modeling process, high speed of optimal design calculation, high readability of design data and high level of design automation, which can greatly improve the design efficiency of designers. It provides a new way of reference for the engineering application of optimization design. The teaching project "teaching, learning, doing" combines to highlight the cultivation of students' applied ability, and improves students' interest in learning and the ability to solve practical problems.
