摘要
为验证自带动力式联合整地机机架结构设计的可靠性与合理性,本文基于ANSYS有限元分析软件,对机架开展静力学与预应力模态分析。首先明确整机结构组成及工作原理,随后通过网格划分、载荷与约束设置,构建机架有限元模型并进行静力学求解,同时在静力学分析基础上完成1~6阶预应力模态分析。静力学结果显示,机架最大应力为96.26 MPa,远低于材料屈服强度,最大变形为1.087 mm,满足强度与刚度要求;模态分析表明,机架前6阶固有频率为22.383~49.694 Hz,完全避开了作业时88~112 Hz的激振频率的共振区间。研究结果为该类型机架的后续优化设计提供了理论参考。
To verify the reliability and rationality of the frame structure design for a self-propelled combined tillage machine,this study conducted static and prestressed modal analysis of the frame using ANSYS finite element analysis software.First,the overall structural composition and working principles were clarified.Subsequently,the frame finite element model was constructed and solved statically through meshing,load and constraint settings.Based on the static analysis,prestressed modal analysis for the first six orders was completed.The static analysis results indicate that the maximum stress in the frame is 96.26 MPa,which is significantly below the yield strength of the material.The maximum deformation is 1.087 mm,meeting the requirements for strength and stiffness.The modal analysis indicates that the first six natural frequencies of the frame range from 22.383 to 49.694 Hz,completely avoiding the resonance range of 88 to 112 Hz during operation.The research findings provide theoretical reference for the subsequent optimization design of this type of frame.
