According to the mechanical characteristics of the bridge, the calculation method for prestress friction loss of the spatial curved prestressed wires is studied. 针对曲线箱形梁的力学特点,对空间曲线钢束摩阻损失的计算方法进行分析。
The pump performance would be affected by the two clearances in such a way that the clearance alters both volumetric leakage power loss and mechanical power loss ( dick friction loss of impeller). 口环间隙通过改变离心油泵的容积损失功率和机械损失功率(叶轮圆盘摩擦损失)影响离心油泵性能。
The magnetic levitated rotor eliminates mechanical friction when it rotates with high speed, but due to eddy loss, hysteresis loss and windage loss of magnetic levitated rotor, there is still a equivalent friction force which is similar with the mechanical friction force. 对于高速旋转的磁悬浮转子或直线运动的磁悬浮动子来说,虽然其消除了机械摩擦,但是由于涡流损耗、磁滞损耗和风损的作用,仍然存在着一种类似机械摩擦的等效阻力。
