一、问题的提出电液振动台的正确安装状态应该是将振动台的基座用大直径地脚螺栓和基础牢固地连接在一起,见图1。或者借助于过渡平台,首先将过渡平台用地脚螺栓和基础牢固地相连,然后再将振动台基座和过渡平台牢固地相连,见图2。但目前不少厂、所已建有地轨式的大基础,因而也就因地制宜地利用地轨式基础通过过渡平台安装电液振动台,见图3。有的甚至将电液振动台直接座落在地轨问的基础上,用压扳螺钉的方式进行固定,见图4。实践证明,后两种安装方法的弊病甚多,
First, the issue put forward Electro-hydraulic shaker correctly installed state should be the base of the shaker with large diameter anchor bolts and the foundation firmly connected together, see Figure 1. Or with the aid of the transitional platform, the transitional platform is first firmly connected to the foundation by the anchor bolts, and then the shaker base and the transitional platform are firmly connected, see Figure 2. However, at present, many factories have already built a large foundation of earth-rail systems. Therefore, they also use the ground-rail foundation to install the electro-hydraulic vibration table through the transitional platform according to local conditions, as shown in Figure 3. Some even electro-hydraulic vibrating table directly located on the basis of the rail asked, with a way to hold the screws fixed, see Figure 4. Practice has proved that the shortcomings of the latter two installation methods,
