双圆盘割草机传动系的应力应变及振动特性分析

Double Disc Mower Drive Train Stress-strain and Structural Optimization

建立了9YG—130型前置式双圆盘割草机第一级传动系的三维模型并进行装配,利用ANSYS Workbench软件建立了装配体的有限元分析模型,对传动系进行了结构的强度、刚度校核及模态分析。通过对有限元计算结果的分析,得到应力、应变分布情况及固有频率和振型特征。结果表明,采用虚拟设计可以显著加快设计进度,改进产品设计质量,为农业机械的虚拟样机后续拓扑优化提供了参考依据。

In this paper, using virtual prototyping technology to build 9YG-130 type of front double disc mower lifting mechanism and the three-dimensional model for assembly, and then use ANSYS Workbench software built assembly finite element analysis model of the structure of the transmission lines were strength, stiffness checking and modal analysis, through the finite element analysis of the results obtained and the stress and strain distribution of the natural frequencies and mode shapes characteristic, the results showed that using gress, improve product design quality, agricultural machinery rides a reference. virtual design can significantly speed up the design provirtual prototyping subsequent topology optimization provides a reference.
