Through the vibration behaviour of beams and shafts of hoisting machinery, the paper proves a fact that this kind of structural frequency bears a relation with distribution functions both of typical size of structure section and of the vibration modal. Moreover, by the use of optimal design of criterion method, a simpler and more feasible optimal method is obtained. This method demands that the point of design be in a feasible range, otherwise the design can only be done with the equation modified by frequency...

Through the vibration behaviour of beams and shafts of hoisting machinery, the paper proves a fact that this kind of structural frequency bears a relation with distribution functions both of typical size of structure section and of the vibration modal. Moreover, by the use of optimal design of criterion method, a simpler and more feasible optimal method is obtained. This method demands that the point of design be in a feasible range, otherwise the design can only be done with the equation modified by frequency and the design point moved to the feasible range.

利用起重机械常用的梁和轴一类结构的振动特性,可推证出此类结构固有频率主要与结构剖面典型尺寸分布函数和振型函数有关的规律。本文还运用准则法的优化设计思想,得出比较简单可行的一种优化方法——最小剖面法,这种方法要求初始设计点在可行域内。如果不在,须用频率修改公式把初始设计点移到可行域内,然后优化设计。

The gantry crane with double beams is a kind of large-scale hoisting machinery universally used in the materials handling in the open all over the world. Its advantages and shortcoming of the operational performance are shown in many aspects.Among them, the horizontal rigidity of the mast's structure is an important index.At present, the conventional design and technical norms are not deep enough in study in the spatial structure, especially in the aspect of appraising and calculating the horizontal rigidity.It has many differences from the real condition.In this article, a comprehensive analysis to the horizontal rigidity of the gantry crane with double beams will be made, and it will give out some new suggestions in the way of appraising and calculating,and also give references to the designers and can help them to formulate a new technical norms in this field.

双梁门式超重机是国内外露天物料搬运普遍采用的一种大型起重机械,用途十分广泛。其使用性能的优劣表现在各方面,其中,门架结构的水平刚度应是一项重要指标。目前,传统设计和技术标准对该空间结构的研究尚不够深入,尤其在水平刚度的评价与计算方面,与实际结构存在较大的差异。本文针对箱形双梁门式起重机的水平刚度进行全面地分析,从中提出新的评价和控制指标,供设计工作和制定技术标准参考。
