单滑轮起重机

In Chapter 9, a more complete optimization model of single boom, leading pulley compensation type luffing system of portal crane is established for the first time and is optimized by the integrated visualized intelligent optimization system.

第九章首次较完整地建立了单臂架导向滑轮补偿式门座起重机变幅系统优化设计模型，并用所开发的集成化可视化优化系统进行了求解，利用本文的研究成果，本章还进一步讨论了抓斗机构的优化问题，这些实际工程问题都验证了本文研究成果的有效性。

In this paper,the optimization of the single boom system withcompensating pulley is studied,in which the minimization of the height difference between theluffing path and the fixed level line is the optimum destination,and the boundary conditions andempiric formulas are constralnt equations.

以变幅轨迹与水平线间的高度差最小为目标，以经验设计公式和边界条件为约束函数，对平衡滑轮补偿法的单臂架系统进行优化，并以80t起重机为例进行计算。其计算结果表明：变幅轨迹曲线有了明显改善。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
