塔式起重机平衡重参数化计算系统

The parameterization calculation system for the counterweight of the tower crane

针对塔式起重机在实际工作中经常出现需要变换臂长,而对应的起升载荷也将变化等问题,研究开发出一套适合实际应用、简洁、方便的塔式起重机平衡重参数化计算系统.本系统根据塔机的工作特点和起重特性,针对塔机的不同臂长状态,利用三维设计软件Pro/E建立塔机主要结构参数化模型,进行结构的快速设计及自动化装配.以VB为系统开发工具,与Pro/E相结合,实现数据的传输与调用,简化了建模与计算等过程.通过算例验证了系统的正确性和可行性.

Aiming at the problems that the tower crane often needs to transform arm length and the corre- sponding hoisting load. varies frequently in the practical situation, a new parameterized calculation system of tower crane counterweight was developed, which was more practical, simple and convenient. The system which was based on the feature and working conditions, could build the tower crane main structure paramet- ric model with Pro/E （the three dimensional design software）, design and assemble automatically, accord- ing to the different length of the crane arm. It could transfer and invoke the data using VB cooperated with the Pro/E as the developing tool, so as to simplify the model and calculating process, which was proven to be correct and feasible by the examples.
