Computational aspects of sensitivity calculations in linear transient structural analysis
… accelerations, and stresses in linear, structural, transient response problems. One significant goal of the study was to develop and evaluate sensitivity calculation techniques suitable for large-order finite element analyses. Accordingly, approximation vectors such as vibration mode …

Design of effective traveling wave sloshing absorbers for structural control
… sloshing absorbers with shallow depths, in structural control applications. An effective means of using intentionally induced liquid sloshing to control low frequency, transient structural oscillations is presented, establishing the sloshing absorber as an effective structural control …

Surface Strain Measurement for Non-Intrusive Internal Pressure Evaluation of a Cannon
… pressure rise created during combustion. A transient structural, numerical modal was created using ANSYS of a 155 mm gun barrel. The pressure gradient was derived using a method outline in IBHVG2 (Interior Ballistics of High Velocity Guns, version 2), and the model was validated using …

Fluid-structure interaction investigation of a medium-sized heliostat
… technologies. Vortex shedding and the resultant transient loadings on a medium sized heliostat are investigated in this paper. Reynolds-Averaged Navier-Stokes (RANS) Computational Fluid Dynamics (CFD) of an operational heliostat is used as a validation case. The Atmospheric Boundary Layer (ABL) …

A Study of the Effects of Piston Secondary Motion on Piston Ring Conformability and Coolant Cavitation in Heavy-Duty Engines
… piston secondary motion and oil transport, transient structural finite element analysis of the cylinder, and a curved beam ring-liner conformability model. Significantly higher ring-liner clearance and higher contact were observed. As a result, higher oil leakage, wear, and combustion gas …

Experimental and Computational Methods for Investigating Automotive Door Closure Sounds
… The impact speeds were 0.851m/s and 1.179m/s. Transient sound pressure measurements from five different door closure mechanisms were collected in a semi-anechoic chamber using a three-element condenser microphone array. Post-processing methodologies such as Sound Pressure Level versus 1/3 …
