摘要
本文系统地阐述了完整系统各种形式的Lagrange方程及其应用;从变质量系统的运动微分方程出发,在利用理想约束假设并定义了质量凝固Euler算子后,推导出变质量系统的Lagrange方程;系统总结了两类机电比拟关系,最后给出应用实例.
This paper systematically throws light on all kinds of the la-grange equations of complete system and their applications and the paper also succeeds in inferring the lagrange equation of variable system after utilizing the ideal control assumption and defining the Euler operator of quality condensation from the angle of the moving differential equation of variable system.Besides, the paper sums up two kinds of electromechanical compare relations and offers the applicable example at last.
