摘　　要：研究新型枝丫材、抚育间伐材等林业剩余物盘式削片机的主轴系统,该削片机刀盘与主轴安装结构的特点,与当下主流安装形式存在差异,验证其主轴系统在切削原木过程中是否符合结构设计要求。采用ADAMS软件与ANSYS软件建立柔性主轴的刚柔耦合模型,在模型中添加切削力周期变化的规律,仿真提取主轴与刀盘连接点位置处主轴轴向与径向振幅情况,得到刀盘在径向的最大振动幅度为175μm,结果按国标对比符合旋转轴长期运行条件。研究结果对新型削片机主轴系统的合理性提供了验证,为削片机主轴系统的结构改进提供了理论依据。In this paper,the spindle system of the new disc chipper for forestry residues such as branch wood,tending timber and thinning timber was studied,and the installation structure of the cutter head and spindle of the chipper was different from the current mainstream installation form,and it was necessary to verify whether the spindle system met the structural design requirements in the process of cutting logs.ADAMS software and ANSYS software were used to establish the rigid-flexible coupling model of the flexible spindle,the law of the periodic variation of cutting force was added to the model,and the axial and radial amplitudes of the spindle at the connection point between the spindle and the cutter head were simulated and extracted,and the maximum vibration amplitude of the cutter head in the radial direction was 175μm,which met the long-term operation standard of the rotating shaft stipulated in the Chinese national standard.This study provides a verification of the rationality of the new chipper spindle system,and provides a theoretical basis for the structural improvement of the chipper spindle system.
