高科技廠房精密機台之隔震設計，除了低加速度傳遞率要求，因設備容許位移空間狹隘，必須限制隔震滑動位移量。本研究提出滾動摩擦滑軌增補阻尼器系統為其隔震方案，該系統隔震機制，乃利用滾動摩擦滑軌介面降低樓板振波傳遞至設備之加速度，間隙彈簧與阻尼器為限位與消能元件。
　　經由電腦模擬與足尺模型實驗驗證，本研究於滾動摩擦滑軌增補阻尼器隔震系統可得以下結論：
1. 滑動面摩擦係數降低時，隔震系統自振頻率小於一般震波頻率範圍，才會有明顯的隔震效果。
2. 彈簧間隙值小時，剛體質量與單側彈簧總剛度構成其系統頻率。當激振頻率高於系統頻率，便得以發揮降低反應加速度之隔震效能。彈簧剛度越大，限位效果越佳，但上部結構反應加速度也會越高。
3. 系統頻率可能因彈簧間隙值放大而降低；當輸入波頻率高於系統頻率時，彈簧間隙值放大，可降低反應中系統頻率分量強度。而彈簧間隙值過大會使低頻系統位移之低頻震盪情形趨於嚴重，高頻系統加速度中高頻帶強度與位移峰值提升。間隙值過大模型，易在部分高頻波輸入時因倍頻現象（harmonics）放大反應。
4. 提升阻尼係數可使低頻系統反應位移低頻震盪情形及位移峰值得到有效改善，但亦使反應加速度隨之提升。
5. 近斷層樓板振波隔震設計佐以阻尼器消能機制，則在低頻系統中加速度可有效控制下來，同時應適量提升阻尼係數與阻尼指數使反應相對位移峰值降低。

　A base isolation design for precision machinery in a high-tech factory building is required for low acceleration transfer and a small amount of sliding displacement because of the limited permissive space between equipment. Therefore, this thesis studies a scheme, rolling frictional guideway isolators added vicious dampers, for the base isolation design. This mechanism reduces acceleration transferred from floor to machinery with guideway isolators, minimizes displacement with gapped springs, and dissolves energy with added dampers.
　According to the result of computer simulation and full-scale shaking table test, this thesis has obtained following conclusions:
1. While the friction coefficient of sliding surface reduces, this isolation system will be obviously effective if the System Frequency lower than the excitation frequency.
2. The System Frequency with small gap opening is composed of the mass of machinery and total stiffness of springs on one side. The isolation system will reduce acceleration peak values if System Frequency is lower than the excitation frequency. Larger stiffness of spring accomplishes limited spacing purpose, but makes machinery to behave in higher acceleration.
3. System Frequency may be reduced because of the enlarged gap opening. Large gap opening can reduce the intensity of System Frequency component when excitation frequency is higher than the System Frequency. Excessively large gap opening not only causes the Low-frequency System a severe low-frequency shaking, but also may raise the intensity of high-frequency acceleration and displacement peak values of the High-frequency System. Excessively large gap opening may also lead to harmonic response if certain high-frequency waves were in the input motion.
4. Increasing the damping coefficient of the Low-frequency System can reduce effectively low-frequency shaking and displacement peak values, but causes higher acceleration peak values.
5. The Base isolation designs against floor response waves caused by near field earthquakes have to dissolve energy with added viscous dampers. Low-frequency System reduces effectively the acceleration peak values. The damping coefficient and the damping exponent should be appropriately improved to reduce relative displacement peak values at the same time.
