摘要
明确结构受载响应的敏感特性及其分布区域,可以有效确保钢闸门安全可靠运行。通过钢闸门强化仿真试验模型,应用ANSYS系统的APDL二次开发技术,提出了结构受载响应高敏感的第一、第二类单元及其分布区域的搜寻方法。工程应用表明,钢闸门结构大部分单元呈现同步受载的特点,并且支臂等局部区域表现出高敏感的受载特性,因此加强结构受载响应高敏感区域的重点监测和维护,可以便捷、实效地实现钢闸的预警决策和安全可靠运行。
The sensitive properties of steel gate response is made clear to load and its distribution,the safe operation of hydraulic steel gate can be effectively ensured.By using the APDL secondary development function of ANSYS through the safety simulation model of hydraulic steel gate,the two types of units of highly sensitive areas response to load and the search method of distribution area are introduced.Engineering application shows the most part of steel gate presents a characteristic of synchronization load and some local areas present highly sensitive load.Emphasis on strengthening the traits monitoring and maintenance of highly sensitive areas response load make it more pertinence and effectivity to ensure the safe operation of hydraulic steel gate in service.
