After an extensive study of the relevant entities the above principle is successfully applied to the derivation of the geometrical stiffness of a beam element in space. The consistency of the present approach is demonstrated by the full agreement with the prior results of the authors based on the...
The flexible crashworthy structure can significantly mitigate the ship impact force on bridge pile.This paper establishes an analytical model to obtain the equivalent elastic stiffness of the structure.The model is composed of a closed circular beam connected to the circular foundation with distributed ...
14. Kneading the muscles in a stiff shoulder will take away the stiffness. 揉捏肩膀上僵直的肌肉可带走僵硬。 15. The computations show that the changes of vehicle velocity have greater influence on the track vertical acceleration, the changes of track stiffness of frog system have also greater in...
A method for calculating the dynamic transfer and stiffness matrices for a straight Timoshenko shear beam is presented. The method is applicable to beams with arbitrarily shaped cross sections and places no restrictions on the orientation of the element coordinate system axes in the plane of the cro...
For the machining process of industrial parallel robots, the gravity generated by the weight of mobile platform and links will lead to the deviation of the expected machining trajectory of the tool head. In order to evaluate this deviation and then circu
A 12×12 stiffness matrix was obtained for the gull-wing lead and solder joint in a plastic quad flat pack (PQFP) surface-mount assembly, using a three-dimensional finite element method. Deformation of the composite structure for each imposed unit displacement (or rotation) was then obtained. ...
The relationship between stiffness distribution and aeroelastic performance for a beam-frame model and a3-D model is investigated based on aeroelastic optimization of global stiffness design for high-aspect-ratio wings.The sensitivity information of wing spanwise stiffness distribution with respect to the ...
After almost twenty years of intense work on the celebrated LaAlO3/SrTiO3system, the recent discovery of a superconducting two-dimensional electron gas (2-DEG) in (111)-oriented KTaO3-based heterostructures injects new momentum to the field of oxides interface. However, while both interfaces shar...
