摘要
针对传统起重机能源消耗量大的问题,以额定起重量 40.5 t 轨道门式起重机为研究对象,对起升机构最 大可回收能量进行分析与计算,配置合理的储能器 超级电容,并对其参数进行了设计与计算,制定了柴油机、 超级电容及双向 DC-DC 变换器的控制策略。进行不同工况下的实验研究,结果显示超级电容供能比超过 75%,能量 回收率达到 85%,能量回收 - 消耗比达到 62%。
In view of the problem of high energy consumption of traditional cranes, taking the rail gantry crane with a rated lifting weight of 40.5 t as the object, this paper analyzes and calculates the maximum recoverable energy of the lifting mechanism, configures the reasonable energy accumulator-super capacitor, designs and calculates its parameters, and formulates the control strategies of diesel engine, super capacitor and bidirectional DC-DC converter. According to the experimental results under di fferent working conditions, the energy supply ratio of the super capacitor exceeds 75%, the energy recovery rate reaches 85%, and the energy recovery-consumption ratio is 62%.
