in this paper free vibration analysis of two rectangular isotropic plates, which are connected to each other by two translational and rotational springs along the edges, are investigated. the equation of motion and associated boundary and continuity conditions are derived using the extended hamilton principle. to solve the eigenvalue problem, the ritz method is utilized. numerical investigation...

Design of springs is a very important step in the design process of inertial sensors. A procedure for computing the spring stiffness for any single-chain configuration of beams and a translator which converts beam-based schematic representation of inertial sensors to higher-level behavioral representation are implemented. Combining the spring stiffness computation with the translator, spring-ma...

A mathematical model is presented to examine the propagation of bending waves on a plant stem that are induced by vibratory excitation from an attached insect. This idealized model represents the insect body as a mass and the legs as a linear spring along with a general time-varying force that is assumed to act in parallel with the spring. The spring connects the mass to a stem modeled as a bea...

The RHIC Beam Abort Kicker Power Supply Systems commissioning experience and the remaining issues will be reported in this paper. The RHIC Blue Ring Beam Abort Kicker Power Supply System initial commissioning took place in June 1999. Its identical system in Yellow Ring was brought on line during Spring 2000. Each of the RHIC Beam Abort Kicker Power Supply Systems consists of five high voltage m...

The integration of the booster synchrotron control system to the SPring-8 control system finished successfully in January 1999. This integration allows us to operate the synchrotron, the beam transport line and the storage ring in a seamless fashion.

<p style='text-indent:20px;'>This research provides a design for complaint constant-force mechanism employing leaf-spring-like beam with variable stiffness to address the negative stroke underutilization issue of bistable beam. By designing compression at each given displacement and ramp slope, this technique allows constant force potentially take full utilization beam's component. Innova...

A photocathode RF gun was built and it has been operated for beam measurement at SPring-8. The cavity was tested by using high power RF up to 18 MW. The electric field gradient on the cathode reached 127 MW/m. After RF conditioning, a laser pulse was irradiated on a copper cathode and the photo-emitted beam was accelerated up to 2.9 MeV. An effective quantum efficiency of the cathode was obtain...

In this study, the improvement of energy harvesting from wideband vibration with random change by using a combination of linear and nonlinear spring system is investigated. The system consists of curved beam spring for non-linear buckling, which supports the linear mass-spring resonator. Applying shock acceleration generates a snap through action to the buckling spring. From the FEM analysis, w...
