Floor Vibration Analysis and Vibration Reduction Treatment Caused by Vibrating Screen

采用振动信号测试系统结合有限元数值模拟的方式,对振动筛造成的楼层振动进行分析,对比发现激振频率和固有频率相近是产生振动的主要原因,找到放大振动的潜在影响因素,并提出了可行的解决方案,针对性的添加阻尼等。对大型设备的放置位置规划,工作设备的周围空间改造和维护具有指导意义。用实验与ANSYS模拟结合的方式,提出了在振动诊断方向上的新的解决思路。

The vibration signal test system is combined with the simulation numerical simulation method to analyze the floor vibration caused by the vibrating screen. It is found that the excitation frequency and the natural frequency are close to each other, which is the main reason for the vibration. The potential influencing factors of the amplified vibration are found and feasible. The solution, targeted to add damping and so on. It is instructive to plan the placement of large equipment and to modify and maintain the surrounding space of the working equipment. Using the combination of experiment and simulation, a new solution to the direction of vibration diagnosis is proposed.
