晋祠圣母殿 宋代彩塑 振动
晉祠聖母殿 宋代綵塑 振動
진사골모전 송대채소 진동
Sacred Lady Hall; Colored Song Dynasty clay statues; Transportation vibration
为了研究公路的交通振动对彩塑损伤状况,对山西省晋祠圣母殿内彩塑进行了脉动和汽车振动测试。脉动测试与分析得到了彩塑基频自振周期、阻尼比及传递函数;单车公路汽车振动测试及利用传递函数进行的多车振动数值计算分析,得到了彩塑在单车行走下的最大位移为3.40×10-2μm,五车纵列行走振动最大位移为1.32×10-1μm,及在不同汽车流下的振动位移。根据彩塑残损情况和振动最大位移角2.24×10-7rad,提出了瞬时振动对晋祠泥质彩塑影响的判定等级和准则;根据疲劳损伤理论和振动测试结果,提出了持久振动对晋祠泥质彩塑损伤的判定准则;根据晋祠泥质彩塑的现状损伤和其在振动时的瞬时位移极限角,提出了不同等级公路应有的避让距离分别为3200m、2400m、1800m、1200m、800m,并对晋祠周围的公路状况进行了判定。
為瞭研究公路的交通振動對綵塑損傷狀況,對山西省晉祠聖母殿內綵塑進行瞭脈動和汽車振動測試。脈動測試與分析得到瞭綵塑基頻自振週期、阻尼比及傳遞函數;單車公路汽車振動測試及利用傳遞函數進行的多車振動數值計算分析,得到瞭綵塑在單車行走下的最大位移為3.40×10-2μm,五車縱列行走振動最大位移為1.32×10-1μm,及在不同汽車流下的振動位移。根據綵塑殘損情況和振動最大位移角2.24×10-7rad,提齣瞭瞬時振動對晉祠泥質綵塑影響的判定等級和準則;根據疲勞損傷理論和振動測試結果,提齣瞭持久振動對晉祠泥質綵塑損傷的判定準則;根據晉祠泥質綵塑的現狀損傷和其在振動時的瞬時位移極限角,提齣瞭不同等級公路應有的避讓距離分彆為3200m、2400m、1800m、1200m、800m,併對晉祠週圍的公路狀況進行瞭判定。

Pulsation and vibration tests were carried out to assess the damage caused by automobile-induced vibrations on the colored clay statues in the Sacred Lady Hall in Shanxi province.Pulsation tests were used to obtain the fundamental frequency of vibration period,the damping ratio and the transfer function of the colored statues;single and multi automobile induced vibration tests were used to calculate the displacement of the statues under varying traffic volume.Based on the condition of the statues and their maximal displacement angles,preliminary rating scales and regulations of instant vibration＇s effect on the colored clay statues in the Sacred Lady Hall is proposed.Based on theory of fatigue damage and vibration test results,criteria for vealuation of effects of constant vibration on the colored clay statues are also proposed.Based on current state of damage to the statues and their maximal displacement angle under vibration,a minimum safe distance from the road is suggested.In addition,the road conditions around the Sacred Lady Hall have been surveyed.
