对重脱轨是电梯震害中是最常见的一种破坏形式。为了研究对重—导轨体系在地震中的响应规律,对带有对重—导轨体系的足尺模型进行了振动试验研究和ANSYS有限元数值模拟。结果对比表明有限元分析结果和试验结果吻合较好,证明了所建立的有限元模型的正确性。根据试验研究和数值模拟可得如下结论:导轨应变响应大于支架;导轨腹面应变响应整体大于导轨翼缘,导轨应变响应在对重上导靴的位置较大;上导靴和导轨之间的碰撞力、脱开位移大于下导靴。
Derailment is the most common type of damage in elevator derailments. In order to study the response of the heavy-rail system to earthquakes, a full-scale model with a counterweight-guideway system was studied by vibration test and ANSYS numerical simulation. The comparison of the results shows that the results of the finite element analysis agree well with the experimental results, and the correctness of the established finite element model is proved. According to the experimental study and numerical simulation, the following conclusions can be drawn: the strain response of the guide rail is larger than that of the support; the strain response of the ventral surface of the guide rail is larger than that of the guide rail, and the strain response of the guide rail is larger in the position of the guide shoe on the counterweight; Force, off displacement greater than the lower guide shoe.
