International Journal of Structural Stability and Dynamics, 2017
A novel concept of a nonlinear oscillator is proposed, based on a bistable element, which operates around an unstable equilibrium point. Contrary to the Quasi-Zero Stiffness oscillators, a totally different redistribution of the stiffness elements is followed, so that any level required static stiffness for the entire system can be maintained.

High-Static-Low-Dynamic Stiffness Isolation with Asymmetric Stiffness Structure
International Journal of Applied Electromagnetics and MechanicsAn asymmetric stiffness structure, comprising a permanent magnet (PM) and an electromagnetic coil (EC), has been designed to create a vibration isolator with high-static-low-dynamic stiffness (HSLDS). The mathematical model of the system is established using the molecular current method and is compared with simulation results. Additionally, a nonlinear

Static Stiffness Analysis of a Novel Parallel Manipulator
Key Engineering Materials, 2012One novel 6-DOF parallel manipulator with hooke hinges is presented to provide precision positioning in this paper. The geometric parameters and spatial architecture of kinematic pairs will influence the system stiffness directly, which impact indirectly the characteristics such as supporting capacity, driving burden and so on. The elastic model of the

Models for Determining the Static Stiffness of Collet Sleeves
2014The most versatile general purpose clamping device is collet chuck. Most of collet chucks use solid thin slotted clamping sleeves made of a hardened steel and ground to a high degree of accuracy on both internal and external surfaces. This paper first presents a straightforward analytical model to determinate the static stiffness of collet sleeves ...

The Increase of the Dynamic and Static Stiffness of a Grinding Machine
Volume 2: 30th Annual Mechanisms and Robotics Conference, Parts A and B, 2006The dynamic stiffness of a grinding machine influences the process stability enormously. Among other things the stability of the grinding process is affected by influences like the specification of the grinding wheel, the condition of the workpiece and machine parameters.

Static stiffness of curcular saw blades
2017The article outlines the technique of strain estimating of a band saw blade. The quality of processing depends on the strain character of a band saw rim, improved quality of processing being provided by the saws where the rim is not displaced in opposite directions over the saw perimeter under axial loading.

Static and dynamic stiffness of reinforced concrete beams
Archives of Civil and Mechanical Engineering, 2012Abstract In this paper experimental studies of reinforced concrete beams are reported. The influence of load on deflections and basic eigenfrequency was investigated. Eigenfrequencies were registered using the operational modal analysis. Static stiffness (on the basis of deflections) and dynamic stiffness (on the basis of eigenfrequencies) were ...
