To extend cable-stayed utility longevity and reduce the frequency of vortex-induced vibration. Firstly, this paper designs a new-style cross-section shape of the stay-cables' casing with the help of aerodynamics. Secondly, it establishes its expression making use of CFD, afterward, it compares the new model with existing and gets the new modle can avoid coming into being significantly vibration. It...
A novel orthogonal 3-leg parallel machine tool (PMT) with 5 DOFs is designed for normal machining a 3D free-form surface s. A CAD variation geometry approach is adopted for pre-solving the extension/rotation of the linear/rotational actuators and the pose of this PMT. First, a simulation mechanism of this PMT is created by using the CAD variation geometry technique. Second, a s and a guiding plane...
