Gaoya dianqi为解决某GIS母线中波纹管的最大压缩位移和疲劳寿命究竟能否同时满足工程指标的难题，应用工程计算和有限元分析分别加以计算，然后通过两种计算结果和实验验证进行比较，以期获得哪种方法更精确可靠。为达此目的，文中给出了工程计算和有限元建模的详细过程。按工程计算方法得到的最大压缩位移结果无法满足工程指标，而有限元分析计算方法，却可以达到工程指标，且有较大的安全裕度。有限元分析还揭示了满足大压缩位移的机理，计算结果符合某GIS工程同时需要的压缩位移和疲劳寿命。经型式试验也验证了模拟的正确性 ...

Gaoya dianqi, 1979 本文对三相全控大功率换流器RC阻尼回路电阻损耗功率的工程计算方法作了探讨。这种近似计算方法,首先将桥臂上的电压按波形分成工频部份与高频振荡部份二大类,分别计算其引起的电阻损耗,其和即为总电阻损耗。在计算高频振荡部份引起的电阻损耗时,为简化计算和便于工程使用,采用了近似估算方法。
