| Abstract: | The two-axes position mechanism of a satellite antenna is a free-floating space rootless and multi-body system.Based on the need of dynamics real-time simulation and control system design,spatial operator algebra(SOA) theory is applied to the multi-body systems modeling and simulation.The dynamics recursion and solution algorithm of SOA is proposed,and the object-oriented idea is utilized to define the data structure of the multi-body system,and to design the flow-chart of the dynamical calculation.This met... |
