機力通風冷卻塔在某燃機熱電廠的應用Induced draft tower
機力通風塔According to the fluctuating property of wind, on the stochastic vibration finite element theory, some calculation formulas of the response, including the along - wind response and the across - wind response, are obtained, the ideology of the torsion vibration in the double - tower structure and the ideology of the double - tower structure ' s dynamical wind load are also put forward at the same time. by using the stochastic vibration module of the general finite element program, the paper analyses the performance of the wind resistance more deeply and fully, discussing the influence on the double - tower structure from the diversification of the different component. the variance law of dynamic displacement and wind - induced vibration coefficient is derived through analyzing structure stochastic vibration, so is the effect of several parameters on dynamic displacement, acceleration and wind - induced vibration coefficient
從結構風振的基本理論出發，通過對脈動風功率譜的分析，推導了結構風振響應（順、橫風向）的計算公式，同時提出了雙塔結構的扭轉振動和動力風荷載計算的思想，在結合通用有限元程序的隨機振動模塊的情況下，對雙塔結構的抗風性能作了深入、全面研究，探討了雙塔結構構件截面的變化對其抗風性能的影響，同時探討了順風向風速譜的選取、風速、參與計算的振型數、風與結構耦合作用是否考慮等因素對分析結果的影響，比較了規范風振系數的計算與隨機演算法結構的異同，並討論了原因，得出一些有意義的結論。In this dissertation, the author summed up the muti - technique in fluid dynamics, heat and mass transferring, mechanical designing and computational technique and studied the conventional pressure spray dryers with different air disperse structure and outlet equipment, at last put forward the theme i. e. the study on combined spin - flow pressure spray drying technology, the main contents were as follows : ( 1 ) the combined spin - flow pressure nozzle was designed whose novel structure has no report at present, and the structural designing parameters were obtained through analyzing the physical characteristic of materials and distribution of particles
