【摘要】 笔者提出由多个液压式激励器组成的组合主动构件,这种构件的轴力、弯矩和剪力可控,采用这种组合主动构件代替拱桥拱肋的某一段,可以形成可控的拱桥.对液压式构件的力学特性和这种组合主动构件的应用前景进行了分析.更多还原

【Abstract】 A type of active composite component composed of several hydraulic components is presented. The axial force, bending moment and shear force of this type of active composite component can be controlled. A controllable arch bridge is formed by substituting several segments of the arch ribs by active composite components. The mechanical properties of a hydraulic component and the prospects of application of this type of active composite component are discussed.更多还原
