摘　　要：为满足实验室纤维铺装的工艺要求,设计耙辊式纤维铺装机构。分析该机构的总体结构、工作原理和主要技术参数,建立三维模型。针对关键部件——螺旋耙辊,分析其运动特性及其在旋转主转动和往复运动双重驱动下梳齿顶点的速度变化;建立刚柔耦合螺旋耙辊的虚拟样机,分析启动瞬间的运动特点,基于ADAMS/Vibration分析螺旋耙辊的自由振动特性。结果表明,所建样机螺旋耙辊运动特性的仿真分析和理论分析一致,在启动瞬间存在振动,但系统是稳态的且处于欠阻尼状态。In order to meet technological requirements for fiber paving in laboratory,a rake roller fiber paying mechanism was designed.The whole structure,working principle and main technical parameters of this mechanism were analyzed and a three-dimensional model was constructed.For a key component,a spiral rake unit,its kinetic characteristics and comb teeth vertex velocity variation under the dual drive of main rotation and reciprocating motion were analyzed;a rigid-flexible coupled virtual prototype of the spiral rake unit was produced,with the movement characteristics at the moment of starting and the free vibration characteristics of the spiral rake roller based on ADAMS/Vibration analyzed.The results show that the simulation analysis and theoretical analysis of the motion characteristics of the spiral rake roller of the built prototype were consistent.There was vibration phenomenon at the beginning of movement.However,the whole system of the spiral rake unit was in steady and under damping status.
