最近在土壤-农机系统力学的研究中,已广泛地应用“相似理论及模型试验”。为了使我国拖拉机和农机行业的同志对它的基本原理和在农机拖拉机上的应用有一个初步了解,作者特编写此文,主要讲述以下内容:绪言,量纲理论,相似定理;量纲分析;无量纲乘积的计算方法;量纲分析的代数理论;模型理论;相似理论及模型试验在土壤-农机系统力学中的应用;共七章。将分期在本刊上登出,希能引起大家的兴趣,并对我国水田行走机构和机耕船的试验研究有所裨益。
In the recent study of soil-agricultural mechanics, “similar theory and model tests” have been widely applied. In order to make our country’s tractors and agricultural machinery industry comrades on its basic principles and applications in agricultural tractors have a preliminary understanding, the author especially prepared this article, mainly about the following: introduction, dimension theory, similarity theorem; dimensional analysis; The calculation method of dimensionless product; the algebra theory of dimension analysis; the model theory; the theory of similarity and the application of model test in soil-agricultural mechanics; a total of seven chapters. Will be staged in the magazine published, hope to arouse the interest of everyone, and China’s paddy walking agencies and pilotage research beneficial.
