    Deflection of uniform plates during vibration

    I agree with you on the simply supported boundary condition and the bouncing. Then floating boundary condition I can think of is a plate floating in air. Then there can never be a physical case where a plate can have a floating boundary condition because it has to be held by some object or sit...

    Deflection of uniform plates during vibration

    Yes resonance happens when there is dynamic loading. Right now I am only talking fundamentals: That if a plate is held on all sides in an edge guide which resembles a simply supported condition, then the deflection is less than if the plate is floating i.e., if the plate is loosley held in the...

    Deflection of uniform plates during vibration

    Which rectangular plate would have higher delection for a G force: a plate free on four sides and a plate simply supported on four sides? I know the resonant frequency is higher in case of simply supported plate. So the deflection would be smaller in simply supported plate because...

    Pressure-Flow performance

    Each curve represent performance at different speeds (RPM). The pressure was measured at the blower outlet and flow was regulated using a valve. The blower discharges air. I am trying to know why in general the pressure remains constant for low discharge. As per theory the pressure should drop...

    Pressure-Flow performance

    Hi, I have a pressure-flow performance for a motor blower. Its attached in the word document. As you may see, the pressure drops pretty fast at lower pressure whereas at larger pressure the pressure stays constant for a considerable amount of flow. My questions: 1. Why the pressure drops that...

    Accelerometer response

    No. I am trying to understand the process because I have never done a vibration test analysis before. Please help.

    Accelerometer response

    Thanks a bunch. I know that accelerometer gives data in volts/g. But I would like to know how the PSD is derived from the raw data. Do I have to know the resonant frequency of the system? And do I have to know the transmissibility? Please explain.

    Accelerometer response

    In what form is the accelerometer responds during random vibration? Or in other words, how does the response plot looks like? Is it in g vs Hz or g^2/Hz vs Hz or g vs time? A known PSD profile is input and the area under the plot is G rms. Thanks.
