Investigation of the effect of buckling initiator on energy absorption of thin-walled circular tubes by using of numerical simulation
Cylindrical thin-walled tubes due to construction and easy installation, high energy absorption capacity are used in the automotive industry as an impact energy absorber. However, the main weakness of cylindrical tubes is in the high initial peak load. Therefore, in this paper, to overcome this weakness, a buckling initiator is used at the top of the tube. This buckling initiator is a steel rod...
متن کاملPattern recognition analysis of acoustic emission signals propagated through a waveguide – A simulation study
Pattern recognition (PR) analysis of acoustic emission (AE) signals for classifying the source mechanisms involved, is a widely accepted practice, if the signals are directly picked up from the test specimen. However, there is an apprehension for the same, when a waveguide (WG) is used to pickup the signals. In the present paper, the validity of PR analysis has been studied on burst AE signals ...
متن کاملEstimating Waveguide Model Elements from Acoustic Tube Measurements
One-dimensional digital waveguides are widely used to model traveling pressure waves along wind instrument bores comprised of concatenated cylindrical or conical sections. Waveguide filter elements model frequencydependent losses and delay (dispersion) occurring during propagation and at any boundary or discontinuity producing reflected and transmitted waves. In this work, a technique is descri...
متن کاملAxial Crushing Analysis of Sandwich Thin-walled Tubes using Experimental and Finite Element Simulation
Application of impact energy absorption systems in different industries is of special significance. Thin-walled tubes, due to their lightness, high energy absorption capacity, long crushing length and the high ratio of energy absorption to weight, have found ever-increasing application as one of the most effective energy absorption systems. In this research, through carrying out experimental t...
