摘要
分析了电梯层门在冲击试验中的4种失效形式。应用几何的方法得到层门最大变形的计算公式。应用动量定理．角动量定理．功能原理．得到层门上部所需锁紧力的计算公式。最后提出了加强层门抗冲击性能的措施。
Four kinds of failure modes of elevator landing door during the shock test are analyzed. The maximum deformation calculation formula of the landing door is derived by the method of geometry. The formula for calculating the upper locking force of the landing door is derived with the theorem of momentum, theorem of angular momentum and theorem of kinetic energy. Finally the measures to enhance the anti-impact resistance of the landing door are presented.
