项目摘要
A test apparatus was designed and assembled to simulate response of structures to an arbitrary seismic ground motion at loading rates much slower than actual seismic response velocity.The apparatus incorporates gears and threads to generate, magnify, and transmit force to a test specimen. Driving force is given by a conventional electric motor with brake.Rotational velocity of the motor is adiusted by a frequency inverter to which signals are sent from a conventional personal computer. The computer also retrieve data from displacement and load sensors through a digital strain meter.A typical time required to conduct a simulated seizmic response test for a selected earthquake ground motion was about one hour when the maximum restoration force was 1.0 ton, the maximum displacement was 6 mm, and the 10 seconds duration of earthquake was devided into 200 time interval steps. That required time corresponds to 18 seconds per one time step.The overall performance of the test apparatus was satisfactory. The threads ensures displacement control loading. Some slackness in the mechanical load tranmission paths requires corrections in determining displacements. Seismic simulation load tests are underway and will be continmed.
设计并组装了一个试验装置,用于模拟结构在加载速率远低于实际地震反应速度的任意地震地面运动下的反应,该装置包括齿轮和螺纹,用于产生、放大和传递力到试样上。驱动力由带制动器的传统电动机提供,电机的转速由变频器调节,变频器的信号由传统的个人计算机发送。当最大恢复力为1.0 t,最大位移为6 mm,地震持续时间为10 s,时间间隔为200个时步时,对选定的地震地面运动进行模拟地震反应试验所需的典型时间约为1 h。所需的时间相当于每一个时间步长18秒,试验装置的总体性能令人满意。螺纹确保位移控制加载。机械载荷传递路径中的一些松弛需要在确定位移时进行校正。地震模拟负载测试正在进行中,并将继续进行。
