摘要
采用有限元分析方法,建立了叶柄的三维计算模型,对叶柄的静、动态特性进行计算,求出了叶柄在载荷作用下所受的应力、产生的变形、各阶固有频率和振型,为优化叶柄结构和改善叶柄的静动态特性提供理论依据。此外,论文对其数据进行了分析,并提出了改进叶柄结构的建议。
The 3 D calculated model of petiole is established with the finite element analysis. The petiole static and dynamic characteristics are calculated, including its stress, deformation, natural frequencies with different orders and the vibration mode under the load. This offers theoretical evidences to the petiole structural optimization and the petiole statie and dynamic characteristics improvement. Moreover, these data is well analyzed and the suggestion is given to improve the petiole structure.
