单臂架起重机匀速变幅控制驱动函数的反求方法

Reverse Method of Uniform Luffing Control Driving Function for the Single Jib Crane

针对单臂架起重机变幅过程中变幅速度不稳定,导致功率损失,引起振动、冲击,造成司机室晃动致使驾驶员疲劳等问题,利用瞬心法提供一种简单、实用的单臂架起重机匀速变幅控制驱动函数的反求方法,依据该函数给出PLC控制的一般思路,为单臂架起重机特别是单臂架门座起重机、固定吊等港口起重设备匀速变幅的实现提供通用方法。

According to the issues of power lose,vibration,impact,cab shaking and driver fatigue caused by the luffing speed-instability of single jib crane,a simple and practical reverse method of uniform luffing control driving function by using the method of instant centre is provided. A general idea of PLC control based on that driving function is also given,which provides universal method for the implementation of uniform luffing on single jib crane,especially on the port cranes,such as the single jib gantry crane and the fixed crane.
