投射式架设跨河电缆的计算机模拟

摘 要

本论文以物理学中的二维变质量理论的应用为背景,分析了具有初速度的炮弹拖动电缆在空中的运动情况.并根据假设将问题适当简化成水平和竖直两个方向上的关于炮弹和电缆的变质量运动问题，推导出相应公式并给出其解,并且在论文中讨论了炮弹的水平射程以及运动的高度分别与炮弹的初速度,射角,炮弹的质量的关系.并应用MATLAB编制出相应的程序,然后给出了炮弹在空中运动的轨迹曲线. 从而在理论上解决了现实生活中架设跨河电缆难度大的问题。

Abstract

The thesis has taken that two thinking in physics is changed into mass theory application as background , has analysed the cannonball having initial velocity dragging moving the cable motion condition in overhead. Mass moves and a problem according to assuming that appropriate simplification becomes the horizontal and erect upper two direction unexpected turn of events about the cannonball and cable with the problem , deduces out corresponding formula gives it's a solution out together,And the mass relation parting from cannonball initial velocity , angle of fire , cannonball for in the altitude having discussed cannonball horizontal range and motion in the thesis. MATLAB applying has woven out and the corresponding program , has given a cannonball out and then trajectory curve moving in overhead. The middle having resolved an actual life thereby in terms of theory is erected striding over river cable degree of difficulty big problem.
