摘要: 通过一阶非完整约束对系统运动限制条件的分析,在Cq空间中给出一阶非完整理想约束力的表示形式.在速度空间中阐明一阶非完整约束力的几何意义.最后证明Appell-Четаев条件是实现一阶非线性非完整理想约束的充分必要条件.

Abstract: Analyzed the restricted condition with 1-order nonholonomic constraint, the form of 1-order nonholonomic ideal constraint force in the space of C^q is given, and the geometric significance in the velocity space is clarified. It's proved that Appell-Chetaev condition is sufficient and necessary condition to realizing 1-order nonholonomic ideal constraint.
Key words: l-order nonholonomic constraint, ideal constraint force, the velocity space, Lagrange's multiplier, virtual work, virtual displacement, Chetaev condition, virtual variation of generalized velocity
