施工升降机作为重要的垂直输送机械,其系统振动分析一直受到广泛关注。本文对施工升降机进行振动分析,建立系统振动力学模型,利用Matlab计算获得在不同载重和不同位置时系统的各阶固有频率,分析各阶固有频率随载重和吊笼位置的变化趋势,确定了系统对于给定初始条件的响应。 As an important vertical conveyor, the construction elevator has been widely concerned about the vibration analysis of the system. In this paper, the vibration analysis of the construction elevator, the establishment of the system vibration mechanics model, the use of Matlab to calculate the different frequencies in different loads and different positions of the system natural frequency, analysis of the natural frequency of each order with the load and cage position trends, identified the system Response to a given initial condition.
