RISLow-Gravity Sloshing in an Axisymmetrical Container Excited in the Axial Direction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The response of low-gravity propellant sloshing is analyzed for the case where an axisymmetrical container is exposed to axial excitation. Spherical coordinates are used to analytically derive ...
A Mechanical Model for Low-Gravity Sloshing in an Axisymmetric Tank
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mechanical model for low-gravity sloshing in an axisymmetric tank is developed using a newly developed slosh analysis method. In this method, spherical coordinates, whose origin is at the top ...
Analytical Implementation of Wave-Absorbing Control for Flexible Beams Using Synchronization Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For wave-absorbing control, the ideal controller transfer function H(s), which connects the sensor output to the control force, contains the imaginary unit i = −1 explicitly. Therefore, H(s) ...
