摘　　要：多功能作业机具有体积小、质量轻、易操控等优点,搭载不同的作业机具可以完成旋耕、开沟、挖坑、打药和除草等作业。为此,利用LS-DYNA和HyperWorks软件分析了园林小型旋耕刀的结构形式,建立了其仿真力学模型,并结合土壤旋切过程的仿真结果,分析了两种旋耕刀作业过程中的受力和形变。同时,试验验证了不同硬度作业土壤的旋耕作业效果,旨在为旋耕刀具结构的参数设计和选用提供参考。The multifunctional work machine has the advantages of small size,light weight and easy handling.It can be equipped with different work tools to complete the rotary tillage,trenching,digging,pesticide,weeding and other operations.For this,LS-DYNA and HyperWorks software were used to analyse the structural form of the small garden rototiller and establish its simulation mechanics model.Combined with the simulation results of the soil rotary cutting process,the force and deformation of the two rotary tiller blade during operation were analysed.At the same time,the test verified the rotary ploughing effect of different hardness of soil,which provided a reference for the parameter design and selection of rotary ploughing tool structure.
