随着集装箱起重机的大型化和机电集成化技术水平的日益提高,对其中的机械制动性能可靠性的要求也越来越高。由于集装箱起重机,尤其超巴拿马型集装箱起重机的制动系统无法在出厂前对其进行多种工况下的原型动态实验,造成产品无法向客户提供重要且应有的性能指标之一的制动特性参数。因此,对集装箱起重机的摩擦制动系统特性制定出一套研究方案并设计出相应的实验装置是完全必要的,也是ISO所要求的。本文首次提出“当量转动惯量”概念,用转轮组来模拟大型起重机升降机构,可对其中关键的制动器在多种工况下的动态特性进行实验测试。文中详细地介绍该集装箱起重机摩擦制动动态特性实验装置的原理及其运行方法。
With the increasing size of container cranes and the increasing level of electromechanical integration technology, the requirements for the reliability of mechanical braking performance therein are also getting higher and higher. Since container cranes, especially super Panamax container cranes, can not be prototyped dynamically under various conditions at the factory, the product can not provide the customer with one of the most important and deserved performance characteristics parameter. Therefore, it is completely necessary to develop a set of research program and design the corresponding experimental device for the characteristics of the friction braking system of container cranes, which is also required by ISO. In this paper, the concept of “Equivalent Moment of Inertia” is first proposed. The runner set is used to simulate the lifting mechanism of a large crane. The dynamic characteristics of the key brake under various conditions can be tested experimentally. This paper introduces in detail the principle and operating method of the dynamic characteristics of the experimental device for frictional braking of container cranes.
