摘要
应用动能定理建立了常速率运动航天器的数学模型并求出两组稳态解 .首先将动能定理推广到受非线性非完整约束系统 .对于受速率为常数约束的运动质点 ,可以应用动能定理建立其运动微分方程 .
The mathematical model of a spacecraft moving in a constant speed is established based on the kinetic energy theorem,and two steady solution are obtained.The kinetic energy theorem is extended to systems subjected to nonlinear nonholonomic constraints.The differential equations of motion of a particle constrained to moving in a constant speed are deduced from the kinetic energy theorem.Two special solutions of the equations is presented.
