torsional pendulum

Finally , the torsional vibration of a rigid disk resting on the saturated grounds under the general torque is primarily discussed by the means of laplace - hankel transform . the general solutions of the torsional moment , stress and displacement are given and the numerical solutions in special cases are also obtained 最后,本文還采用laplace - hankel聯合變換技術初步分析了在一般動扭矩作用下飽和地基上剛性圓板的扭轉振動問題,給出了扭矩、應力和位移的通解,并給出了特例情況下的數值解。

Abstract : a new type cold frame is intruduced . the deformation of unsymmetry section steel after cooling is mainly eliminated by reversely curring it on line , ensuring the achievement of automation of meticulous repair . at the same time the disposing principle of equilibrium weight on the driving axis of cold frame drived by eccentric wheel was improved . the torsional moment of transmission shaft and power of electric motor are reduced by the method 文摘:介紹了一種新型冷床,通過在線對非對稱型鋼進行反向彎曲,基本上消除了非對稱型鋼冷卻后的變形,保證了精整工序自動化的實現.同時,提出了偏心輪驅動的冷床驅動軸上平衡重的配置原則.此方法可降低傳動軸上所受的扭矩,減少了電動機的功率

Having analyzed the check result of the torsional moment on the scene of the big hexangular high - stength bolts conjuncted in the service based on the engineering example , the paper gives two reseans about the lose of pretension the earlier checking of the moment and the inaccurate maintenance method 摘要通過某工程實例,對在役大六角高強螺栓連接副現場扭矩復驗結果進行了理論分析,找出了高強螺栓預拉力損失的主要原因:一是現場扭矩檢測時間過早,導致預拉力損失不穩定,前期損失較多;二是使用中維護不夠。

In allusion to section modality and transverse joint of common span bridges , we choose two kinds of calculating theories in transverse distributing calculate process : the theory of rigidity crossbeam and the theory of hinged girder and slab . making the use of the theory of optimized design , i constitute mathematics model and choose appropriate calculated method . and find the form and detail dimension of section when beams of the bridge satisfy bending moment ^ shearing force and torsional moment 在用橫向分布理論計算單梁扭矩過程中,針對現有常用跨徑橋梁的截面形式和橫向連接狀況,選取了兩種計算理論:剛性橫梁法和鉸接梁(板)法,利用結構優化設計原理,建立主梁承載力的數學模型,選擇合適的優化計算方法,得出在滿足彎剪扭承載力要求時主梁的細部尺寸。

Contrast between this machine and traditional rolling screen : adopt lower driving , the carrying ability is great , running is stable which settle the problem , such as great torsional moment of central drive , startup loading is great with shock of chain driving 本機與老式滾筒篩相比,因為采用下傳動有承載能力大運轉平穩,特別克服了中心傳動扭矩巨大,起動負荷大,鏈傳動沖擊等缺點。

The latest constructing machine and the newest technology were adopted to ensure that the borehole is perpendicular to the rock face of roof and that the depth of borehole and the torsional moment of the anchoring bolt meet the design requirement 采用最新錨桿施工機具及工藝,保證鉆孔垂直于頂板巖面,孔深及錨桿扭矩滿足新型機械錨桿的設計要求。

For reducing the disadvantageous influence of the the relaxation of strain and the lose of pretension on the structure , the time span of delaying scene torsional moment checx and accurate maintence method are given 為減少高強螺栓預拉應變松弛和預拉應力損失對結構的不利影響,給出了延遲現場扭矩檢測的時間區間和正確維護的方法。

Unique pu - metal binding technology enables the company to achieve the technology of increasing torsional moment , improving loading and never loosing thus largely prolong the life of components 獨有的聚氨脂-金屬粘結技術,實現了增大扭矩提高負載不脫膠的目的,極大地延長了配件制品的使用壽命。

In order to make the gear has higher torsional moment , the steel workpiece may directly embedded in the gear 為了使輪具有更高的扭矩,可以考慮將機械加工的鋼件直接鑄造在輪里。
