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 为突破上述两点多体系统动力学瓶颈,二十世纪九十年代以来,美国nasa科学家g rodriguez等人发展了基于空间算子代数( spatialoperatoralgebra ,简称soa )的多体系统动力学方法。
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 但由于美国对我们保密,此类软件无处购买,且其原理与方法亦各自分散在有关资料文献中,因此我们必须提炼和总结soa的基本原理和方法,并在此基础上消化吸收,进一步开发基于空间算子代数的动力学仿真软件,为我国机电工程各有关领域的产品开发提供高效动力学分析工具。
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 本文系统地论述了空间算子代数理论体系,基于空间算子代数的多体系统动力学是对工程、科学和应用数学的重大贡献,它通过比拟力学和控制以及信号处理等相关学科,找出这些学科的共同点,把kalman , ricatti等发展的计算结构和方法应用到多体系统动力学解算,实现了力学与控制学科的相互渗透,在将来通过不断深入研究,这种学科的交叉与渗透必然会进一步加强,由此可进一步奠定机械电子工程学科完美统一的理论基础。
