3D Vibration and Stress Analysis of Insulators

Abstract

Abstract. Numerous dedicated computer packages are of much help at insulator designing process. Making a digital model of an insulator and then performing computer simulation for the phenomena occurring both inside and outside of it, becomes nowadays a vital information source on the insulator behavior at established (both given and analyzed) operational conditions. Such a process appears to be necessary at the stage of insulator design process. The computer simulation results can verify the data obtained during actual insulator operation or laboratory tests, which make it possible to do suitable adjustments still at the design stage in order to include some innovative solutions, operational features, improvements as well as to get some economical advantages resulting from them.Selected problems associated with static electricity and mechanical phenomena occurring at insulator operation have been addressed in this paper. The calculations have been made with ANSYS Multipurpose Finite Elements Method Package as well as the MSC/PATRAN v.8.5, the latter used mainly for mechanical purposes [6].
