Cylinder dryer is a dind of rotatin continuous drying equipment with internal heating conducting - style, certain thickness of materials film theres to the lower trough of materials under the rotating cylinder. heat is transferred to the internal wall of the cylinder through pipes and misfired ahain to the external wall and to materials film, to evaporate and damnify moisture in materials film so as to dry materials
滾筒乾燥機是一種內加熱傳導型轉動連續乾燥設備。旋轉的滾筒通過其下部料槽,粘附著一厚度的料膜。熱量通過管道輔送至滾筒內壁,傳導到滾筒外壁,再傳導給料膜,使料膜中的濕度得到蒸發、脫濕、使含濕份的物料得到乾燥。( 2 ) on the basis of continuity equation, momentum conservation equation, energy conservation equation, and substantial equation, coupled thm governing equations are derivated with giving up the assumption of local thermal equilibrium, adopting thermal elasto - plastic constitutive relation, taking the effect of temperature gradient on groundwater seepage ( analogous to soret diffusion ) and the effect of viscous dissipation of groundwater on temperature field of rock mass into account
( 2 )根據連續性方程、線動量平衡方程和能量守恆方程以及相應的物性方程推導了飽和巖體溫度場-滲流場-變形場三場耦合作用控制方程組。在推導控制方程組時舍棄了「局部熱平衡」假設,採用了熱彈塑性本構關系,考慮了溫度梯度對地下水滲流的影響(類soret效應)以及地下水的粘性耗散對巖體溫度場的影響。The type and working principle of 4wd which connected by cohesive shaft coupler are introduced, the effect of motor vehicle speed and tyre sliding rate on rotation difference of cohesive shaft coupler are described
介紹了採用粘性聯軸器連接的四輪驅動形式和工作原理,闡述了汽車速度、輪胎滑移率對粘性聯軸器轉速差的影響。Comparing the fitted expression with the established theory expression of the angular velocity, the equivalent viscous damping coefficient is gained. the closed form algorithm of the state space method is employed to solve the system dynamic equation with time - varying coefficients. the dynamic problem of a linkage mechanism with four joints is taken as example to show that the presented models and methods are correct and practicable
引入求解線性微分方程的狀態空間法,並對其求解時變系統運動微分方程的具體步驟進行了推導;在此基礎上將實測獲得的運動副等效粘性阻尼系數代入系統動力學方程,求解后獲得了考慮運動副阻尼的平面彈性四連桿機構的模擬結果;結果表明運動副的阻尼在一定程度上對振動具有抑制作用。The early studies are mostly focused on the method of gluing piezoceramics on structural surfaces, which has some disadvantages such as difficulties to protect the ceramics and the connection wires, bad coupling with only one surface glued on the base materials, low signal - to - noise ratio etc. these problems can be solved using the embedded piezoceramics, and furthermore, the piezoceramics can be placed in the optimal positions, especially in the optimal deepness for the piezo - actuators, according to an optimization algorithm befor e they are embedded, so the actuator effects and sensor signals are thereby enhanced
早期的研究主要集中在表面粘貼壓電片的結構,表面粘貼壓電片具有一些無法克服的缺點。本文著重進行利用埋入復合材料結構的壓電傳感器和壓電驅動器對其振動進行主動控制的相關理論和實驗研究,並介紹其相應結果。埋入型壓電材料的優點主要是能保護壓電傳感器和作動器及其連線、增強壓電材料和基體材料的耦合、優化埋入壓電陶瓷的深度和厚度可增強壓電傳感器的測量信號並提高信噪比等。分享友人
