In the advent of 20th century , with the transformation of economy and society , america realized industrialization and urbanization . so the old legal system could not adapt these new changes and need relevant adjustment . in 1916 , new york appeal court overruled the traditional privity of contract principle in the case of macpherson v . buick motor co . , a landmark case 19世紀末20世紀初,美國完成了經濟和社會的轉型,實現了工業化和基本的城市化,舊的法律制度難以適應社會的新變化,亟需作出相應的調整。

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,并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。

Adams ( automatic dynamic analysis of mechanical systems ) is a simulation software of mechanical system used most widely in the world . based on the adams virtual model technology , the automobile suspension is regard as a multi - body system which parts connect and motion each other . with the help of adams / view , this paper established multibody dynamics model of macpherson front suspension of chamber car which is increasingly wide used in modern car , and the effects of suspension parameters when wheel travel or turn were studied . the adams entity numeric suspension kinetics simulation provides an efficient and updated tool for developing suspension system Adams ( automaticdynamicanalysisofmechanicalsystems ,即機械系統動力學分析軟件包)是世界上應用最為廣泛的機械系統動力學分析軟件,基于adams的虛擬樣機技術,可把懸架視為是由多個相互連接、彼此能夠相對運動的多體運動系統,本文利用adams view軟件,建立了目前在現代轎車上應用越來越廣泛的麥弗遜式前懸架的某轎車前懸架的多體動力學模型,并對車輪跳動和轉向時,懸架的各種參數的變化進行分析。

Meanwhile , on the fundamental parameters that can be acquired in the primary design stage of a new car or a car which it has put in used , this paper utilizes adams / car to establishes the simulation parametric modeling of a suspension according the topology structure of macpherson front suspension system , in this model , we considered the front suspension system , steering system and the tire model in detail , and the bushing effect was included in this study , and it is very convenience to carry out kinetics / elastic kinetics simulation . all kind of the suspension parameters on handling and stability and automobile comfort were analyzed Adams的實體數值懸架運動學仿真分析為懸架的設計開發提供了一種先進高效快捷的方法。與此同時,本文依據麥弗遜式前懸架的拓撲關系,利用設計階段的新車或者是正在使用的汽車的所能取得的基本參數,借助adams car建立了懸架參數化模型,在這個模型里,考慮了轉向系統、輪胎、襯套等因數,因此可以方便地進行懸架運動學彈性運動學分析。

Because of its characteristics of simple structure , low cost and space economy , macpherson suspension has become the most popular independent suspension since its emergence . hence , the kinematic analysis of macpherson suspension has great significance . in this paper , the dimensional positions of points on the left macpherson suspension while the front left wheel turns and jumps are calculated with the method of dimensional coordinate transformation 本文通過研究用于轉向車輪的麥弗遜式懸架的結構特點和運動特性,采用空間坐標變換方法,準確計算出前轉向車輪在轉向和跳動情況時麥弗遜式懸架上點的空間位置,建立了轉向車輪麥弗遜式懸架在車輪轉向和跳動時的物理模型和數學模型。

A premiere of the api , jointly launched by the dh and committee on promoting acceptance of people living with hivaids , will be held during the hong kong silver shield basketball tournament 2005 at macpherson playground , mong kok tomorrow at 4 pm 此短片的首映由?生署及接納愛滋病患者促進委員會舉辦,于明日下午四時,在旺角麥花臣球場舉行的香港籃球銀杯賽賽事中播放。

Since the 1980s , supermodel elle macpherson ( left ) has been dubbed the body for her statuesque figure ? and she ' s even used the name in her skincare and lingerie lines 上世紀80年代以來,澳大利亞超級名模埃勒?麥克弗森(左)以其雕像般優美的身材獲得了“完美身軀”的昵稱,她甚至還把這個名字用在了自己的護膚品和內衣產品上。

“ i was the most popular guy at the college , “ said macpherson , now 72 , a retired journalist living in monticello , utah , about 240 miles southeast of salt lake city “在大學里,我可是最受歡迎的人, ”麥克弗森說。現年72歲的他是一位退休記者,住在猶它州的蒙蒂塞洛。這個小城位于鹽湖城的東南方,相距約240英里。

In 1955 , macpherson was watching televised coverage of the opening of disneyland for the media and invited guests on july 17 , 1955 , a day before the park opened to the public 1955年7月17日,就在迪斯尼樂園對公眾開放的前一天,迪斯尼邀請媒體和貴賓參加了樂園的開幕儀式。麥克弗森正好看到了相關的電視報道。

Dave macpherson may have been the first paying guest at disneyland when the theme park opened its gates 50 years ago , but he didn t even have time for one ride 50年前,當迪斯尼主題公園首次對外開放時,戴夫麥克弗森可能是第一位買票入園的游客。但是,當時他連在公園轉一圈的時間都沒有。

“ i said , “ boy , i sure would like to go out there , “ said macpherson , who figured he might draw a prize for standing first in line “我說, ‘好家伙,我肯定得去逛逛, ’ ”麥克弗森說。他想如果排在最前面的話,可能會得到點獎品。

In the top ten , with singer natalie imbruglia , blanchett and model elle macpherson appearing . “ people who are confident without a “那些不化妝看上去仍然自信健康快樂生氣勃勃的人是我眼中的自然美女。 ”

The crowd steadily grew overnight to about 6 , 000 people , and macpherson made sure no one got in front of him 直到一個小時之后,其他人才陸續出現。一晚上,人數逐漸增多,最后約有6000人排隊等候。
