研究结果表明,漓江为雨源性河流,降雨时空分配极不均匀,70%的降雨量集中在漓江上游区域,全年62.7%降雨量和降雨时间集中在四个月内(即4~7月),最大的日降雨量可达415.8mm;降雨量最小的月份出现在12月至翌年1月,仅100~110mm,占全年降雨量的6%左右,由此直接影响流域河川径流季节性的变化,造成洪水期和枯水期现象,周期性水量的变化是不为人们意志改变的一种自然规律。

The mechanism of instability wrinkling in the process based on minimum energy principle is revealed, uniform mathematic description of the wrinkling wave on the strip of in-plane bending is established, the internal and external energy is deduced by energy method, and a uniform criteria of internal and external wrinkling is established; then how to combine the criteria with the FEM simulation system to make the numerical prediction of wrinkling into reality is also resolved in the paper. The effects of the forming parameters on the deforming result are analyzed by the uniform predict criteria. The results show as follows: as the compress width increase, external wrinkling first come into being, then internal winkling do, and finally in-plane bend occur; the loading wedge angle increase, internal winkling first come into being, thenin-plane bend do, and finally external wrinkling occur; in-plane bend is possible to occur with a increase of the strain-hardening exponent and the strength coefficient; and the effect of the friction factor may be ignored.

2揭示了板带不均匀压下面内弯曲成形过程基于能量原理的失稳起皱机理,提出了统一的描述内外缘起皱波形的函数,采用变分法推导了服从该波形函数的内外缘起皱能,建立了统一的起皱预测准则;将新建立的统一的起皱预测准则引入到数值模拟系统IBS中,数值预测结果与实验结果的吻合较好;分析了成形过程各参数对起皱的影响规律:随着接触变形区宽度的逐渐增大,先是发生外缘起皱,然后发生内缘起皱,进而才出现稳定成形;随着实际加载楔角的增大,先是发生内缘起皱,然后发生稳定成形,进而出现外缘起皱;硬化指数和强化系数增大,易于稳定成形;摩擦因子对起皱的影响不明显;而且接触变形区宽度对起皱的影响最大。
