高压电气设备的减震设计方法研究
|
摘要
依据电气设备结构特点和功能性等要求,与建筑物减震设计不同,电气设备减震设计有其独特特点。笔者在中国对高压电气设备的减震设计方法进行了较为系统明确的研究,内容涵盖到减震设计的初步设计、减震分析计算等方面,并将该设计方法成功地应用到一个试验实例中。研究表明,这种方法对于指导高压电气设备的减震设计和工程应用均有参考意义。
Due to structural characteristics and functional requirements of electrical equipments,the damping design for the equipments is different from that for buildings.Based on preliminary design and vibration reduction analysis and calculation and details of seismic design in electrical equipments with energy dissipation devices,the method of damping design for the system is studied more systematically and earlier.And the method is successfully used for a test case.The results of the study on the method of damping design show that it is a reference for the seismic design of the electrical equipments and engineering application in China.
