通过对轿厢振动分析可知:振动一般有垂直振动、横向振动和复合振动三种。目前需要改善这三种振动的方法不少。比较普通的是在轿厢壁外侧粘附一层腻子或黑醇酸隔热胶,并将其拉毛,以改变轿厢质量分布及固有频率,起减振消音之效果。但是不够经济。使用腻子一台电梯一般材料费就需100元(还不包括厅门,且层楼越高,花费越大),使用黑醇酸隔热胶效果固然好,但除了成本高,劳动强度也大,以年产400台计,需花费4万多元。若使用107
Through the vibration analysis of the car, we can see that there are three kinds of vertical vibration, lateral vibration and compound vibration. There are currently many ways to improve these three types of vibration. It is more common to attach a layer of putty or black alkyd heat-insulating glue on the outside of the car wall and pull it out to change the mass distribution and natural frequency of the car and to play the role of vibration damping. But not economical. The use of putty for an elevator requires 100 yuan for general materials (not including the hall door, and the higher the floor, the greater the cost). The effect of using black alkyd insulation is good, but in addition to the high cost, the labor intensity is also high. With an annual output of 400 units, it will cost more than 40,000 yuan.
