电子计算机在理论力学中的应用——静力学、运动学系统分析通用程序初探

APPLICATION OF ELECTRONIC COMPUTER FOR THEORETICAL MECHANICS——SYSTEMS ANALYSIS WITH GENERAL-PURPOSE PROGRAMME FOR STATICS AND KINEMATICS

本文研讨的是计算机在理论力学中的应用。根据计算机的特点,突出力学的基本概念,编制了静力学、运动学系统分析通用程序。本程序中,静力学部分的输入元少,计算精度高;运动学部分的运动状态分析,由'过程分析'代替了'瞬态分析',因此能清楚地描述整个运动过程。此外,计算机在动力学问题中的应用,也提出了一些设想。

This paper is to explore the application of computer for theoretical mechanics teaching.We have organized a general-purpose programme of statics and kinematics,according to the character of computer and attending to the basic concept of mechanics.The programme needs not too much input element,and is of high accuracy in calculating static questions;while in kinematic questions,the "momentary analysis" is no longer applied,but,instead,the "non-momentary analysis",and so the whole motion process in kinematic questions could be described clearly. In addition,the paper offers a preliminary idea of applying computer for dynamic questions.
