摘要
本文针对立轴风车因叶片材料,结构形式及空、实心轴不同而产生不同的|J_p-J_d|(转动惯量)对风车临界转速的影响进行了初步研究.为了能用普洛尔(Prohl)法进行实例计算,作者提出了计算风车叶片|J_p-J_d|时翼型截面与矩型截面的等价转换原则和回转轴上的平均分配原则.
The effect on the critical speed of vertical windmills due to different |JP- Jd|, resulting from different blade materials, different forms of the structure and hollow or solid shaft used, has been studied. Calculation, results show that, since the moment of inertia |Jp^Jd| of windmill blades is large, the gyroscopic couple MG produced affects significantly the critical speeds of the system. This effect must be taken into account in windmill design.
