影响自由落体偏离运动的因素及其模拟

The Factors of Influencing the Deviation of Free Falling Body and its Imitation

对自由落体在下落过程中发生南偏和东偏现象的影响因素进行归纳总结和对比,利用Matlab进行数值模拟,直观体现了各因素对偏离运动的影响。发现东偏主要由科里奥利力引起,而惯性离心力不均和引力不均对东偏影响甚小,但对南偏却影响很大;同时发现南偏值极小,在相同下落条件下,东偏值比南偏值大得多。

This paper summarizes and contrasts the factors of influencing the flee falling body＇s SB and EB phenomenon during its falling process. At the same time, it utilizes Matlab to imitate the parameters of influencing the deviation, and reflects all the factors＇ influencing degree of deviation iconically and intuitively, finding that EB mainly caused by Coriolis force, while the odds of Centrifugal inertial force and gravitation have little influence on EB, but have great influence on SB; meanwhile, finding that the value of SB is tininess, in the same falling condition, the value of EB is much larger than SB.
