In order to break through the two bottlenecks of the multibody system dynamics , in 1990s , the scientist of nasa g . redriguez and the others have developed a method based on spatial operator algebra of multibody system dynamics 為突破上述兩點多體系統(tǒng)動力學瓶頸,二十世紀九十年代以來,美國nasa科學家g rodriguez等人發(fā)展了基于空間算子代數(shù)( spatialoperatoralgebra ,簡稱soa )的多體系統(tǒng)動力學方法。
So we must abstract and summery the principle and method of sptial operator algybra . based on which then digesting and absorbing , we should develop the effective dynamic simulation software based on spatial operator algebra , for the sake of providing effective simulation software for the elecmechanical project sphere of 但由于美國對我們保密,此類軟件無處購買,且其原理與方法亦各自分散在有關資料文獻中,因此我們必須提煉和總結soa的基本原理和方法,并在此基礎上消化吸收,進一步開發(fā)基于空間算子代數(shù)的動力學仿真軟件,為我國機電工程各有關領域的產品開發(fā)提供高效動力學分析工具。
In this paper , the spatial operator algebra theory has been dissertated systemtly it is the great contribution to project , science and appled mathematics for the multibody system dynamics based on the spatial operator algebra . it compared mechanics with cebernetics , signal process and other relevant subjects , and find out their common points , and applicated the algorism structure developed by kalman and riccati to the resolvation of multibody system dynamics , and realized the mutual penetrate from mechanics to cebernetics . in the future , such penetrate will be strengthened more , so which will form the ideal and unitive base of mechatronical project subject 本文系統(tǒng)地論述了空間算子代數(shù)理論體系,基于空間算子代數(shù)的多體系統(tǒng)動力學是對工程、科學和應用數(shù)學的重大貢獻,它通過比擬力學和控制以及信號處理等相關學科,找出這些學科的共同點,把kalman , ricatti等發(fā)展的計算結構和方法應用到多體系統(tǒng)動力學解算,實現(xiàn)了力學與控制學科的相互滲透,在將來通過不斷深入研究,這種學科的交叉與滲透必然會進一步加強,由此可進一步奠定機械電子工程學科完美統(tǒng)一的理論基礎。
