摘要
对振动磨机动态载荷的测定分析是对其进行可靠性分析的首要任务。用数据采集器对磨机的运动参数进行了在线测量,给出加速度曲线和加速度幅值谱图,据此计算出运转过程中的动态载荷均值和变异系数。分析认为,磨机振动箱体的质心不与转轴重合和参振体质量在轴向分布不均,分别为箱体两侧和沿轴向各位置在横向平面内加速度差异的原因。
The measurement and analysis of the dynamic load in a vibraton ZM2800 is the first step to study its reliability.The movement parameter of this vibratom is measured on line by a data collector.The acceleration curve and amplitude are obtained to calculate the dynamic load in running.The reason of different values of accelerations at different points is given that the mass center of the vibrating box isn's fit to the axis center,as well as the mass of vi- brating box distributes along the axis unequally.
