Random Dynamic Response Analysis of Porcelain Pillar Electrical Equipment under Earthquake
2023 3rd International Conference on Electrical Engineering and Control Science (IC2ECS)(2023)
摘要
The nonlinear characteristics of electrical equipment are mainly caused by its structural characteristics and different materials of equipment component flange adhesive parts. Ignoring these nonlinear factors will lead to errors in the seismic calculation of equipment. In this paper, the nonlinear random dynamic response of single-section porcelain strut electrical equipment underground motion excitation is studied. Considering the nonlinearity of flange connection, the nonlinear dynamic equation of single-section porcelain strut equipment underground motion excitation is established. Due to the non-stationary characteristics of ground motion, the random dynamic response of the system is analyzed by Monte Carlo numerical method, and the influence law of nonlinear parameters on the system response is analyzed.
