摘要
以风力发电齿轮箱时间序列载荷谱的处理为研究背景,提出了一种将时间序列载荷简化为一定数量载荷谱的处理方法。该方法以ISO6336标准为基本思想,在考虑六自由度载荷的情况下,对原始的时间序列载荷谱进行简化处理。处理后可得到在同一转速下的六自由度载荷,经过处理后的载荷谱可以作为设计载荷,方便的输入国内外主流齿轮箱商业计算软件中进行系统变形分析。并将简化后的载荷谱与风机厂商提供的扭矩载荷谱进行了齿轮强度对比,结果显示,两个载荷谱得到的结果存在微小差异,但简化后计算时间大大降低。该处理方法可供风电齿轮箱厂商及其他齿轮箱厂商的载荷处理及相应的程序编制提供参考,具有一定的实际应用价值。
A method of simply wind turbine time history loads have been studied in the article,it can be converted the time history loads into some number of load duration distribution.It is based on the standard of ISO6336 by considering 6 degrees of freedom.The loads gotten by this method can be used to the designing loads of the wind gearbox by inputting it to the currently commercial gearbox designing software to calculated the system deformation.A comparison between the calculated loads spectrum and the torque spectrum provided by wind turbine factory have performed based on gear strength,the results presented slightly difference,but the calculating time decreased a lot.The method provided a preference to the wind gearbox manufacturer and other gearbox manufacturer process and program the design loads,and have some values of practical applications.
