过山车圆形立环轨道分析

Roller Coaster Circle Loop Analysis

基于加速度分析过山车圆形立环轨道曲线.首先给出过山车车辆通过立环的必要条件.然后对最简单的圆形立环轨道进行分析,分析乘客通过圆形立环所承受的Z向加速度的变化,从而得到过山车圆形立环轨道的缺点及现代过山车不采用圆形立环的原因.最后得出过山车轨道设计的基本方法.

Based on the acceleration,the roller coaster loop track curve is studied.Firstly,the necessary condition for roller coaster to pass through the loop track are given.Then it analyzes the change of Z-direction acceleration that passenger’s bearing through the loop track for the simplest circular vertical ring track,so as to get the shortcomings of the circular vertical ring track of roller coaster and the reasons why the modem roller coaster does not use the circular vertical ring.Finally,the basic method of roller coaster track design is obtained.
