带式输送机头部滚筒卸料运动轨迹计算

,1.皮带机参数：,,,,,,,,,

,,,带速V＝,2.0000,m/s,,,,,说明：表中青色部分可以编辑，

,,,卸料处皮带机倾角β＝,,,3.5,度,0.061086524,rad,黄色部分是计算不必编辑（除非，

,,,卸料滚筒半径R＝,,0.5,m,,,,你想更改它），否则影响结果。

,2.判断条件：,,,,,,,,,

,,上运,V2/(R*g)=,0.81549,S1,,,,,

,,,,,S2,"1＞V2/Rg＜cosβ，物料绕头部滚筒作一段圆周运动,并越过最高点,走一个角度θ,到达cosθ=v2/(Rg)的那一点作抛物线运动,如图5所示",,,,

,,,,,S3,,,,,
