Optimal structural design of a portable column jib crane based on ANSYS;
基于ANSYS的定柱式旋臂起重机机械结构的优化设计
The contrast results of optimal design and traditional design show that the optimal design corresponded well in mechanical performance with each part of the structure for the column jib crane,realizing the best matching between completed economy and reliability.
传统设计的定柱式旋臂起重机,存在着结构笨重和刚度不足的双向缺陷。
This paper introduces the cause of the stress analysis of metal structural of the column jib crane the type of BZ2 -4×5 A4 using the finite- element software ANSYS.
介绍了利用大型有限元分析软件ANSYS对BZ2-4×5A4型定柱式旋臂起重机金属结构进行应力分析的过程,阐述了在分析过程中模型建立、网格划分、边界条件的处理等主要步骤方法,得出了该结构的应力与位移分布图,为进一步改进其受力情况和结构设计提供了理论依据。
A straight transfer transformation(STT)model for a rotary crane was built in order to reduce the number of variables in the model,calculate the optimal input control voltages quickly,and control the rotary crane concurrently.
目的通过建立旋转起重机直线搬送方式的二维数学模型,减少变量数量,实现最优控制输入信号的快速计算,以达到对旋转起重机进行实时控制的目的。
