摘要
EN8111998中附录M关于曳引力计算给出了一个非常复杂的实例公式．自从发表以来的10来年中．世界各地不少的电梯工程师对此公式提出了各式各样的疑问，实际运用时尤其对其原理深感困惑。本文从不同侧面对此公式进行了详细的推导，作者最后给出了钢丝绳为任何倍率时均能适用的普适公式。
the author discussed the calculation of traction force for lift system consist of complex pulley and steel reeving. By two quite other derivation methods it is proved that the formula delivered in M.3, Annex M, EN81-1：1998 is full of prunes, not only the masses of suspension rope and the moments of inertia of suspension pulley, but also the moments of inertia of pulley for tension device, the convert dynamic force are out in their reckoning completely. Further more, the author pointed out some nonstandard formats for mathematical expression, and ultimately gave out a universal formula, it can be applied for any reeving rate.
