Calculation of radial force of radial HTS magnetic bearing

Cryogenics, 2021
Abstract Radial force (radial stiffness) is an important performance index of radial HTS magnetic bearing. However, it is difficult to calculate it due to the complexity and particularity of the structure. It is of great significance to establish an effective and convenient method to predict the radial force of radial bearing.

Quantitative radial force measurements of Woven EndoBridge devices

Interventional Neuroradiology, 2023
Background Lateral/radial forces and the mechanical properties of Woven EndoBridge (WEB) devices have significant importance for therapeutic success. In other words, adequate apposition of the lateral wall of a cerebral aneurysm is critical for preventing recurrence or re-rupture risk.

Characterization of Radial Forces in Z Stents

Investigative Radiology, 2001
The purpose of this study was to evaluate the effects of variation in design parameters on the resultant radial force. We evaluated the influence of wire gauge, leg length, and number of bends on the radial force produced by z stents and compared these with radial forces produced by commercial stents.

Force transmission through the radial head.

The Journal of Bone & Joint Surgery, 1988
A technique has been developed to study the transmission of axial force across the radiohumeral joint during simulated active motion of the elbow. Variations in the line of action and in the amount of muscle load, as well as in rotation of the forearm during flexion and extension of the elbow, were assessed.

Radial force of coronary stents: A comparative analysis

Catheterization and Cardiovascular Interventions, 1999
High radial force has become an essential feature of new coronary stents. These stents are expected to exhibit sufficient radial force and minimum radial recoil when deployed in atheromatous lesions of various morphologies. The aim of this study was to compare the radial force of 17 coronary stents in vitro (Anglodynamics, ACS Multilink, AVE Micro II ...

Self-expanding stent modelling and radial force accuracy

Computer Methods in Biomechanics and Biomedical Engineering, 2012
Computational simulations using finite element analysis are a tool commonly used to analyse stent designs, deployment geometries and interactions between stent struts and arterial tissue. Such studies require large computational models and efforts are often made to simplify models in order to reduce computational time while maintaining reasonable ...

Radial Force-Current Characteristic Analysis of Three-Pole Radial-Axial HMB

2016 IEEE Vehicle Power and Propulsion Conference (VPPC), 2016
The magnetic bearings are important component of magnetic suspension flywheel system. As three-pole magnetic bearings can be driven by three-phase inverter which is low power consumption, small volume and low cost, the three-pole magnetic bearings have attracted wide attention of scholars in the world.
