| 摘 要： | 建立了包括钢丝绳参数激励横向振动在内的电梯系统动力学模型,基于参数振动的有关理论,提出了"电梯钢丝绳参数共振频带"的概念:在电梯系统中,导致钢丝绳横向参数共振的垂直激励频率不再局限于一个单一的数值及其邻域,而是一个较宽的数值区间,该数值区间的上下限分别是钢丝绳横向振动一阶固频上下限的2倍。数值仿真验证了该观点的正确性。 |

| Abstract: | A dynamic model of an elevator system considering parametrically-excited lateral vibration of its hoist ropes is set up. Based on the theory of parametric vibration, the concept of parametric resonance frequency band of the elevator rope is presented. According to this concept, for the elevator system, the vertical excitation frequency causing the lateral parametric resonance of the hoist rope is not restricted to a single value and its neighbouring region, but an interval. The upper and lower limits of this interval are equal to twice of those of the first order natrual frequency of the elevator rope lateral vibration. Numerical simulations show the correctness of the authors' view points. |
