我试图从起重机臂的风速数据中产生一些机械应力信息,当它在0到90度之间时,每个角度的数据都保存在它自己的文件中。当我只做一个文件/角度时,我的脚本运行正常,但是当我尝试使用任何类型的循环来执行所有角度时,它将创建文件,但只有第一个文件中有任何数据。我是初学者,对Python不太了解,所以我希望有人能发现一些我错过的简单内容。我已经包含了源数据的简短示例文件:Windspeed source file - cut down
import math
file = open("C:/Users/Jacob/Desktop/BOM Data/HD01D_Data_074272_999999999523840.txt", 'r')
boomDirection = 0
vaneSpeed = 120
maxShear = 75.97043478
maxVonMises = 500.0216811
while boomDirection < 91:
data_file = open("Bolt Stress - " + str(boomDirection) + " Degrees.csv", 'w')
line = file.readline()
line = file.readline()
while line != '':
try:
if len(line.split(','))>1:
windSpeedHigh = int(line.split(',')[19])
windSpeedLow = int(line.split(',')[22])
windDirection = int(line.split(',')[14])
relSpeedHigh = math.sin(math.radians((90-(boomDirection - windDirection))))*windSpeedHigh
relSpeedLow = math.sin(math.radians((90-(boomDirection - windDirection))))*windSpeedLow
VonMisesHigh = (maxVonMises/vaneSpeed)* relSpeedHigh
VonMisesLow = (maxVonMises/vaneSpeed)* relSpeedLow
data_file.write(str(round(VonMisesHigh,1)) + ('\n'))
data_file.write(str(round(VonMisesLow,1)) + ('\n'))
except ValueError:
pass
line = file.readline()
data_file.close()
boomDirection = boomDirection + 1
