摘　　要：松土器作为悬挂安装在推土机机械尾部的一种工作装置,广泛使用于各种工况。采用现代设计方法可以有效地提高设计的效率和质量,通过对卡特D11T型推土机松土机构分析后对其进行结构改进,采用三维运动仿真方法对改进后的松土器进行运动学、动力学分析。在UG中依照实物真实尺寸建立虚拟样机模型,利用ADAMS和MATLAB仿真软件分析研究松土器强制入土工况下松土齿不同伸长量对地面的作用力。分析结果表明:改进的松土器结构和受力合理,在松土齿的升降控制方面更加方便,很好地扩大了其有效工作范围和灵活性。As a working device suspended and installed at the rear of the bulldozer machinery, the ripper is widely used in various working conditions. The use of modern design methods can effectively improve the design efficiency and quality. After analyzing the loosening mechanism of the Carter D11 T bulldozer, the structure is improved, and the three-dimensional motion simulation method is used to analyze the kinematics and dynamics of the improved ripper. The virtual prototype model is established in UG according to the actual size of the object, and the force of the ripper on the ground when the ripper teeth in the soil are at different elongations is analyzed using ADAMS and MATLAB simulation software. The analysis results show that the structure and force of the improved ripper are reasonable, and it is more convenient to control the lifting and lowering of the ripper, which greatly expands its effective working range and flexibility.
