    THE EFFECT OF THE SUPPORTING RING ON THE TENSION COEFFICIENT OF THE WIRE ROPE CIRCLE
    支环对钢丝绳绳圈张力系数的影响
    Making use of large and general finite element analysis software ANSYS to analyze the different supporting position of brace wheel and with or without supporting annulus,etc. Made the final conclusion and bring up constructive suggestion.
    本论文利用大型通用有限元分析软件ANSYS对矿山提升机滚筒筒壳进行了深入的研究,分析了滚筒在光简和不同形式木衬下的承载特性,对支轮支撑位置不同,支环有无等不同方面,进行了分析,得出了最终结论,并对现场提出了建设性的建议。
    The evenness of soybean /cotton blended yarn with same twist, count and yarn construction increased initially and then decreased with the increasing percentage of soybean protein fiber;
    纱线的临界捻系数大体上随着大豆纤维含量的增加而降低,32支纱线的临界捻系数大于相同捻系数、混纺比和纺纱方法的45支纱线,环锭纱临界捻系数大于相同捻系数、混纺比和支数的Sirospun纺纱。 随着大豆蛋白纤维含量的增多,45支环锭大豆蛋白纤维/棉混纺纱的断裂强力逐渐降低,其它系列纱线的断裂强力先降低后增大。
    Moreover, the intensity of friction wheel under different work conditions are analyzed, including the conditions being subjected to the biggest static tension function and being subjected to the broken-out function, including the conditions when supporting rings are set and not set, the conditions when use different shell thickness, different supporting ring thickness and different supporting wheel thickness.
    并分别对摩擦轮在各种不同工况时的强度作了分析,包括摩擦轮在受到最大静张力作用、受最小破断力作用、有无设置支环时的情况、选用不同壳厚、不同支环厚以及不同支轮厚度时的各种工作情况。
