Materials, board thickness and structures of turning bows are improved. 对转子弓的材质、板厚(BT)和结构做了改进。
This paper puts forward a simple method to calculate temperature stress coefficient in the procedure of board thickness design of cement concrete pavement. 针对编制水泥混凝土路面设计程序中的温度应力计算问题,给出了水泥混凝土路面厚度设计中温度应力系数的数值计算方法。
Finally, the factors which affects the composite truss joint limit bearing capacity are analyzed, the results shows the board thickness is a major factor in external joint, while the web member thickness is a major factor in ear plate joint. 最后对影响组合桁架节点极限承载力的因素进行分析,结果表明,外接式节点中节点板厚(BT)度是主要因素,耳板式节点中腹杆壁厚对节点承载力有较大影响。
The synthesis comparison web plate altitude, ledger wall thickness, web plate thickness, kneading board thickness and concrete slab thickness and finally carries on the optimized design analysis to the composite beam. 综合比较腹板高度,底板厚(BT)度,腹板厚(BT)度,顶面板厚(BT)度和混凝土板厚(BT)度等因素对组合梁的影响并最终进行优化设计分析。
That increasing entry board thickness accuracy of holes location is reduced, cover plate reasonable use way can effectively improve the accuracy of hole location. 盖板厚(BT)度的增加会导致孔位精度降低,盖板合理的使用方式可以有效的提高孔位精度。
