船舶舵机传动机构的冲击振动及优化控制研究

摘要

The impact vibration is a very common phenomenon in the running process of a mechanism for steering gear with clearance.In order to study the relations between the size of clearance and the impact vibration, some experiments are conducted on an experimental device which is based on a mechanism system for steering gear.Besides, some different control strategies are designed to reduce the strength of impact vibration.The results show that under different control strategies, the strength of impact vibration varies greatly.Thus, it can reduce the strength of impact vibration of the mechanical equipment in the process of operation by optimizing the control strategy at the start of the mechanism.%针对船舶舵机传动机构工作过程中产生间隙所导致的振动冲击现象,构建了船舶舵机传动机构的缩比试验台架,开展不同部位、不同间隙情况下的冲击振动试验研究.在复现传动机构间隙振动特性的基础上,开展了传动机构启动瞬间的不同控制策略研究.结果表明,通过优化传动机构启动瞬间的控制策略,可以显著减小该传动机构间隙导致的振动冲击强度.
