本文论述了用于建筑行业的各种类型起重机的有效载荷运动的一个新颖的减振方案,如移动式起重机、臂式或塔式起重机等等一些可以进行改造的现有设备。在这个领域,大多数研究都集中在通过控制速度和加速度来消除各种惯性力方面。然而,风效应,车轮的滑移(量),或支承的沉陷等因素的真实模化几乎是不可能的。本文提出了一个不考虑风效应,车轮的滑移(量),或支承的沉陷等因素来控制有效载荷的摆动的方法。起重机装置了该系统后,这个控制方案是基于在悬挂绳上产生一个周期性的平衡力和力矩来抑制摆动。装置在悬挂绳上的反馈控制系统有能力提供廉价的和容易采用的解决方案。在研究过程中,这个控制方案是通过在起重机结构部件上的有效栽荷和钢丝绳系统的去耦来完成的。对于许多材料吊运工作来说,有效控制有效载荷将能够提高安全性、生产率和节省时间。
This article discusses a novel damping scheme for payload movement of various types of cranes used in the construction industry, such as mobile cranes, arm or tower cranes, and some other existing equipment that can be retrofitted. In this area, most research has focused on eliminating various inertial forces by controlling speed and acceleration. However, true modeling of wind effects, wheel slip (amount), or bearing subsidence and other factors is almost impossible. This paper presents a method to control the wobbling of the payload regardless of the wind effect, wheel slip (amount), or bearing settlement. After the crane is equipped with the system, this control scheme is based on suppressing periodic oscillations in the suspension ropes and moments. The feedback control system mounted on the hanger has the ability to provide a cheap and easy-to-use solution. In the course of the study, this control scheme was accomplished by decoupling the effective load on the structural components of the crane and the wire rope system. For many material handling operations, effective control of the payload will improve safety, productivity and save time.
