摘要: 针对纺织工艺对筒纱改性和染整中遇到筒纱脱液甩干的问题,设计了可用于高转速大惯量环境的脱液转笼结构,并对其进行了剪切力、弯矩校核分析。依据材料力学分析结果,提出了改进后的转笼结构。利用有限元分析软件分别对改进前后的转笼结构进行仿真分析,结果表明改进后的转笼结构有效控制了变形量,大幅度降低了所承受的最大应力,改善了疲劳安全系数。数值模拟结果给高转速大惯量脱液转笼的结构设计和使用工况设计提供了理论依据。Abstract: Aim at removing the residual liquid within the barrel-yarn efficiently in yarns modification and dyeing, akind of rotating cage was designed for using in the high-speed and large-inertia environment and it was checked withthe shearing force and bending moment.Then the structure of rotating cage was improved according to the results ofanalysis based on the materials mechanics.Then, Simulations were conducted for the original and improvedstructures of rotating cage by using the finite-element analysis software, respectively.The results show that thedeformation of the rotating cage is effectively controlled and the maximum stress has a substantial reduction and thefatigue safety coefficient is also increased for the improved rotating cage.The present studies provide theoreticalreference for the structural design of the work condition of the high speed and large inertia rotating cage for removalof liquid in barrel-yarn.
