摘要:
某铁矿石破碎筛分车间布置了9台破碎机,且破碎机基础平台与主厂房结构没有脱开.破碎机的工作扰力导致基础平台与主厂房结构振动严重.为了分析破碎筛分厂房的振动性态,并评估其振动安全性,用自由振动法和脉动法现场测试了结构动力特性参数,并测试了破碎机不同开启工况下的结构和基础平台的振动位移.建立了有限元模型,并进行模态分析和谐响应分析,有限元计算结果与现场动测结果基本一致.研究表明,破碎机引起的破碎筛分厂房振动超限;随着开启破碎机的增多,结构的振动位移相应增大,但局部振动和破碎机的开启工况有关
Abstract:
There are nine crushers in a crushing and screening iron ore plant, and the foundation platform of the crushers is not separated from the main plant structure. The disturbing force of crushers leads to serious vibration of foundation platform and main plant structure. In order to analyze the vibration performance of the crushing and screening plant and evaluate its vibration safety, the structural dynamic characteristic parameters are tested in site with free vibration method and pulsation method, and then the vibration displacement of the structure and foundation platform under different working condition of crushers are measured. A finite element model is established, and then modal analysis and harmonic response analysis are done. The calculation results are basically in accordance with the test results. The study shows that the vibration of crushing and screening plant induced by crushers are overrunning. The structural vibration displacement increases with the increase of opening crushers, but the local vibration is related to the working condition of crushers
