摘要:在直驱多轿厢电梯运行中,乘客客流交通模式是影响电梯系统运行性能的一个重要因素。为了提高系统的服务标准,制定合理的群控调度策略,实现系统的优化调度,设计了基于目的层预约的直驱多轿厢电梯群控系统。在乘客客流交通信息提前预知的情况下,利用模糊逻辑控制,通过建立隶属度函数、模糊规则等步骤对多轿厢电梯系统的客流交通模式进行识别。最后,通过应用实例将模糊控制与BP神经网络算法进行对比,结果表明,在试验样本有限的条件下,基于目的层预约的直驱多轿厢电梯群控系统中采用模糊逻辑控制可以更加方便、准确地识别不同的客流交通类型,这为系统进一步的优化调度奠定了基础。

Abstract:Wire ropes are widely used in many industries. Depended on its using conditions, there are many forming terminations. Among these terminations, wire rope fixed in socket with zinc has been used popularly for its excellent fixation ability and easy operating. However, the mechanical property of wires in socket has not been well studied, because it is very difficult to handle the composite structure for wires and zinc in socket. In this article, the strand wires in the zinc socket termination was studied with finite element method. The domain superposition technology ( DST) was introduced to deal with the composite structure of wires and zinc in the socket. The results had shown the effective of the strand socket termination. In addition, strand wires were effective only in the front half of the socket basket length. It could be deduced that manufacturing defects in the back half of the socket would not reduce the strength of the termination, while defects in the front half were much more significant.
