The kinematic performance of the macpherson suspension on a real vehicle is studied, and the changes of the front wheel alignment and the motion of the front wheel in the longitudinal and the transversal directions are figured. based on the requirements of general layout, a constrained optimization design model is set up with the steering cross rod ball joint position as the optimization variables ( design parameters ), and the sum of steering cross rod length interference while the left front wheel turning and bouncing as the objective function. and the optimization results are worked out by programming on computer
針對一種實際車型上的麥弗遜式懸架，計算分析了轉向輪跳動時前輪定位角和車輪橫向、縱向滑移量的變化情況，並根據實際車型上麥弗遜式懸架的空間布置要求，建立了以轉向橫拉桿斷開點空間位置坐標為優化變量，轉向橫拉桿斷開點空間布置坐標可變化范圍為約束條件，車輪轉向和跳動時轉向橫拉桿長度干涉量為目標函數的約束優化設計模型。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。
