摘要
根据Shinozuka随机模拟理论,采用Matlab编程对某110kV输电铁塔18m、20m高处质点脉动风速谱和自然风速谱进行数值模拟,并将模拟风速谱与Davenport标准风速谱进行比较,结果表明采用Shinozuka随机模拟理论能实现对脉动风速谱的模拟,模拟结果有效、可信。
The nature wind speed spectrum of two masses joint with height 18 m and 20 m of a 110 kV transmission tower is simulated by Matleb software based on the Shinozu- ka random simulation theory. The simulation wind speed spectrum is compared to spectrum which cited by GB5009 to demonstrate its reliability, the results show that the Shino- zuka simulation wind speed pectrum can describle the two masses joint wind characteristic very well.
