Obtained by emtp program and the egm, this paper studies on lightning protection performance on 500kv double circuit transmission line the distributed parameter model of tower is built when analyzing the back stroking lightning protection performance for double circuit line, it can truly reflect the spreading course of lightning current on the tower, furthermore, considering the randomness of working voltage ' s phase when lightning strokes the top tower and supposing the probability of lightning appearing arbitrary phase in a cycle of ac is equal, this paper brings forward the statistical method to calculate the rate of back stroking on double circuit line
本文利用emtp程序、擊距法對500kv同桿雙回線路的耐雷性能進行了研究。在分析同桿雙回線路的反擊耐雷性能時，建立了桿塔的分佈參數計算模型，此模型可以真實地反映雷電流在桿塔上的傳播過程。並針對雷擊塔頂時，導線運行電壓相位角的隨機性，本文假定雷擊出現于交流一周期的任一角度區間內的概率相等，提出了利用統計法計算同桿雙回線路的反擊跳閘率。Third, through employing the 2 - d lumped mass model and the single period objective function inversion method developed in this paper, and taking the measured structure response to a harmonic excitation at the top of structure in field as the reversion objectives, the linear physical and mechanical parameter inversion is performed in ansys by using apdl
第三，採用二維集中質量模型和本文提出的單周期目標函數反演方法，把頂部激振下實測的結構動力響應作為反演目標，利用apdl語言，在ansys軟體中實現了系統線性物理力學參數的反演。Unnecessaryclamping in the process of bending the pipe, andthe specially - designed lifout attachment makes plcing andtaking more conveninent and the cycle of bending pipi shorter, and effi - ciency higher
彎管過程中無需夾緊，且特別設計頂出機構，放、取管方便，彎管周期短，效率高。First, study the concept and the key technology for dfc and analyze every factor influencing the products " cost within the products " life cycle ; second, set up the estimating model of products " cost based on the function to meet the modem products " design idea of the " top - down ", unifying the products " cost and structure on this functional concept ; third, based on the functionally estimating model of the products " cost, propose two grades of products " cost estimating method based on the function. the method can be used in the cost " estimation in the whole course of product design ; finally, regarding solidworks as the developing platform, delphi as the programming tool, structure a based on function - based products " cost estimating system to tentatively prove the practicability and feasibility of this text ' s estimating method
第一，研究面向成本設計的概念和關鍵技術，面向產品全生命周期分析影響產品成本的各項因素；第二，建立基於功能的產品成本估算模型，以適應「自頂向下」的現代產品的設計理念，將產品成本與產品結構在功能這一概念上得到統一；第三，在基於功能的產品成本估算模型的基礎上，提出了基於功能的產品成本兩級估算方法，此方法可用於產品設計全過程中產品成本的估算；最後，以浙江工業大學碩士學位論文摘要solidworks為開發平臺， delphi為編程工具，初步構建了基於功能的產品成本估算系統，驗證了本文估算方法的實用性和可行性。In order to get top of the next 5 - year cycle, add 5 years to any bottom
