Impact of Static & Dynamic load at the base of High Speed Turbo Generator Using Three Dimensional Finite Element Stresses
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2016, Vol 3, Issue 2
Abstract
This paper is meant to disseminate the state-of-the-art works on the importance of vertical ground motion and horizontal ground movement under high speed generator in the power sector. The author particularly likes to raise these with worst possible moment when the turbine gave high amplitude under the high frequency compared to the natural frequency. From the collection of works worldwide, it is concluded that neglecting vertical component of the ground motion may lead to serious underestimation of the demand, over-estimation of the capacity and thus jeopardize overall structural safety . At this sensitive period of transition the author from his capacity, as a keen professor of the structure of structural dynamics and vibration engineering for vertical motion and its effects on the structure likes to make few recommendations to analyze the important structure in civil engineering Hence the author highly recommends the modern approach and soft ware to analyze structure using Finite element method for any desired depth below the important structure. The mathematical modeling followed with the finite element modeling. The impacts of the worst possible moment with the help of vertical and horizontal movement are evaluated. The basis of the design load over the foundation and the impact of the stresses over the large area are predicted. The bearing pressure at the different layers may be predicted to deign for the large amplitude of vertical movement. The structural components for design of the turbine can be verified with the help of the three dimensional stresses. The realistic approach became the three dimensional stresses analysis compared to two dimensional stresses were established
