Abstract

This article presents research carried out using physical data from the experimental construction of an overhead crane. This article aims to determine the dynamic behaviour of the cart-pendulum system when the hoisting mechanism hits the new bumper design at the end of the girder support structure with selected speed and bumper material to the length of the wire rope. This research shows the influence of the horizontal speed of the hoisting mechanism on the bumper force during a collision with a standard buffer and its modifications. The presented model can be the basis for modelling more complex cases, and its assumed role (i.e. the ability to determine the angle of deflection of the rope during an impact) has been confirmed and is possible to use in a specific case of an overhead crane on an industrial scale. Preliminary analysis of the construction of the bumper considered reveals its positive features, aiming, among other goals, to reduce the acceleration and force acting on the crane cart in emergency situations.

新型起重机保险杠设计采用能量吸收装置系统

本文介绍了利用桥式起重机实验结构的物理数据进行的研究。本文旨在确定当起重机构以选定的速度和保险杠材料撞击梁支撑结构末端的新保险杠设计时，推车-摆锤系统的动力学行为。研究表明，在与标准缓冲器碰撞时，提升机构的水平速度对缓冲器力的影响及其改进。所提出的模型可以作为建模更复杂情况的基础，其假定作用（即在冲击过程中确定绳索偏转角度的能力）已经得到证实，并且可以用于工业规模的桥式起重机的特定情况。对所考虑的保险杠结构的初步分析揭示了其积极特点，旨在减少紧急情况下作用在起重机推车上的加速度和力。
