| 摘 要： | 针对旋耕机210普箱的结构特点,应用模态分析理论对其进行了约束模态的有限元分析。在Pro/E软件中建立了210普箱的三维实体模型,在有限元分析软件ANSYS中采用四面体单元对其进行了网格划分,建立了箱体的有限元模型。采用Block Lanczos法进行模态求解,计算出箱体前10阶约束模态的固有频率和相应振型,通过振型分析找到了箱体振动的薄弱部位,并提出了相应的修改措施,为箱体结构的改进设计及其动态响应分析提供了理论依据。

| Abstract: | Finite element analysis for constraint model was conducted on the 210 general box of rotary tiller using modal analytic theory according to its structural characteristics.3-dimensional solid model of the gear box casing was established using Pro/E,and tetrahedral element was used to get its gridding partition in ANSYS.The natural frequencies and corresponding vibration modes of the first ten steps of the 210 general box casing were worked out by using Block Lanczos.By the analysis of vibration modes,the wea... |
