The performance characteristics of a truss core sandwich panel design based on the 3D Kagom e has been measured and compared with earlier simulations. Panels have been fabricated by investment casting and tested in compression, shear and bending. The isotropic nature of this core design has been confirmed. The superior performance relative to truss designs based on the tetrahedron has been demo...

A 3D mathematical model of orthodontic archwire with rectangular curve is established. Simplified 3D solid model of orthodontic archwire bending robot, which is consistent of bending die, support structure and archwire are established by Creo software, then the simplified model of bending die is put into ANSYS Workbench. Material parameters the contact condition and boundary conditions are set ...

This paper reports results of the test of HTS conductor manufactured by Intermagnetics General Corporation (IGC). The HTS version of the CESR dual bore quadrupole magnet has been analyzed using data obtained in this test. 1 HTS test The main purpose of the experiments described below was to obtain HTS characteristics needed for magnet design. The prime goal was to measure the HTS performance de...

This paper proposes an endoscopic forceps manipulator with 2-DOFs bending mechanism by multi-slider linkage mechanisms and 1-DOF wire-driven grasping mechanism. Careful design of the linkage channels and restoring springs enabled unique, independent and stable bending procedure from −90 to 90 degrees on the horizontal and vertical plane to secure large working space. The manipulator consisted o...

Piezoelectric nanogenerators (PNGs) are capable of converting energy from various mechanical sources into electric energy and have many attractive features such as continuous operation, replenishment and low cost. However, many researchers still have studied novel material synthesis and interfacial controls to improve the power production from PNGs. In this study, we report the energy conversio...

A fully printable and conformal antenna array on a flexible substrate with a new LeftHanded Transmission Line (LHTL) phase shifter based on a tunable Barium Strontium Titanate (BST)/polymer composite is proposed and computationally studied for radiation pattern correction and beam steering applications. First, the subject 1× 4 rectangular patch antenna array is configured as a curved conformal ...
