为了对一些工业设施和建筑结构进行振动分析和抗震设计,有关单位已经开始研制模拟地震振动台,这种振动台要求后面和加振器的连接支承部分在传递一个方向加振力的同时,还具有与其垂直方向运动的二个自由度,还要求其承载能力大,磨擦阻力小,并且在台面倾斜时具有一定的自位能力。目前,在国外已经出现了采用静压支承作连接器来满足上述要求的振动台。我们根据有关单位的要求,也进行了这种静压支承的研制和试验。该静压支承的特点是我们首次采用了闭
In order to carry out vibration analysis and anti-seismic design for some industrial facilities and building structures, the relevant units have started to develop a simulation seismic shaking table, which requires that the connecting support portion of the back and the vibration-absorbing device transmits vibration in one direction as well as Has two degrees of freedom with its vertical movement, but also requires its carrying capacity, friction resistance is small, and in the table tilt has a certain self-capacity. At present, there has been appeared in foreign countries using hydrostatic support for the connector to meet the above requirements shaker. According to the requirements of the relevant units, we also carried out the development and test of hydrostatic support. This hydrostatic support features the first time we used closed
