Calculation Method for Flight Limit Load of V-band Clamp Separation Shock

Ultimate Axial Load Capacity of V-band Clamp Joints

Band clamps with a flat bottomed V-section are used to connect a pair of circular flanges to provide a joint with significant axial strength. Despite the wide application of V-band clamps, their behaviour is not fully understood and the ultimate axial strength is currently only available from physical testing. This physical testing has indicated that the ultimate strength is determined by two d...

Nonlinear Analysis of a Power Amplifier inc C Band and Load Pull Technique Calculation USING VOLTERRA SERIES

In recent years, nonlinear circuit analysis techniques have been extensively investigated. One of the most important reasons is the application development of solid-state devices at microwave frequencies. Different methods have been used to analysis large signal behavior of these devices. In this paper load-pull curves (one of design requirement) are obtained using Volterra series. The main adv...

Classical and Numerical Approaches to Determining V­section Band Clamp Axial Stiffness Research Article Open Access Classical and Numerical Approaches to Determining V-section Band Clamp Axial Stiiness

V-band clamp joints are used in a wide range of applications to connect circular anges, for ducts, pipes and the turbocharger housing. Previous studies and research on V-bands are either purely empirical or analytical with limited applicability on the variety of V-band design and working conditions. In this paper models of the V-bandaredevelopedbasedon the classical theory of solid mechanics an...
