摘　　要：滚筒式打麻辊是简易苎麻剥麻机的核心部件,由柴油机驱动,主要作用是将喂入的苎麻条麻骨打碎。柴油机工作时产生的机械振动造成打麻辊的疲劳寿命和工作性能大幅降低。在这个过程中,打麻辊中紧固L型刀片的螺栓受影响最大。螺栓松动会造成L型刀片松动甚至脱落导致机器严重受损。为解决上述问题,本文研究柴油发动机的振动机理,建立合适的振动模型,运用MATLAB分析振型提出改进方案,最后通过样机试验来验证方案的可行性。Drum type ramie beating roller is the core component of simple ramie stripping machine,driven by diesel engine,the main role is to feed ramie strip bone broken.The fatigue life and working performance of the roll are greatly reduced due to the mechanical vibration of the diesel engine.In this process,the bolts fastening the L-shaped blade in the hemp roll are most affected.Loose bolts may cause l-shaped blades to loose or even fall off,resulting in serious damage to the machine.In order to solve the above problems,this paper studies the vibration mechanism of diesel engine,establishes a suitable vibration model,uses MATLAB to analyze the vibration mode and puts forward an improvement scheme,and finally verifies the feasibility of the scheme through prototype test.
