摘要或動機

自從九二一集集大地震以後，中、小學對於防震教育是更加的重視，一次又一次的防震演習\r
還不夠，還讓學生到地震演練室去體會更逼真的地震實境。在地震演練室的下面就有一個六\r
軸動感平台，六軸動感平台的運作是各軸的伸縮長度不同而模擬地震的，而用彈簧製成的震\r
動台也可以達到模擬地震的效果，去做一些關於地震的研究實驗。地震有各種不同的震動方\r
式，多半是垂直的上下移動或是水平移動，不同的地震對於相同的建築物的影響也有所不同；\r
而地面上有各式各樣的建築物，有的高有的低，所以相同的地震對於不同的建築物的影響也\r
會有差別。\r
Since the disastrous Earthquake 921 happened three years ago, the primary schools and junior high\r
schools have stressed on the anti-earthquake education and training. Except for the anti-earthquake\r
drills they take the students to an earthquake show room to experience more realistic earthquakes.\r
Beneath the earthquake show room there’s a 6 degree of freedom Steward platform. The platform\r
simulates the earthquakes by varying the length of the 6 axis. We also designed a platform by springs to\r
simulate the earthquakes. There’re several types of earthquakes mostly horizontal or vertical .\r
Different earthquakes have different effects on the same buildings. Earthquakes of the same amplitude\r
will have different effects on different buildings.
