【摘要】 对门座起重机筒形支柱结构加载和卸载工作状态进行了有限元动力响应计算,分析时考虑了风载荷的影响,在此基础上研制并实施了应力(应变)在线监测系统。实际运行结果表明,此系统能够确保起重机的正常运行,避免事故的发生。更多还原

【Abstract】 The dynamic response of the loading and unloading process in the working state of cylindrical supporting shell of portal crane is analyzed. The finite clement method is used and the influence of wind load is taken into account. The inspection system is developed and used to inspect the online working state . The result shows this system can ensure the normal operation of crane and avoid accident.更多还原
