What is the best way to come up with a good PSD based on the acceleration response of the part (at some point). What is an allowable delta dB range on the PSD spectra?
a. When I specify a PSD profile taking into consideration acceleration responses in all three orthogonal directions, where I...
Thanks guys for your answers.
What we normally do is we collect acceleration data on a component while sweeping an engine through its speed range and determine the worst speed condition (high acceleration in low frequencies). I am interested to know as to what is a good frequency range to...
What is the frequency range normally employed for vibration testing of diesel engine components (10Hz to 2kHz) normally for providing PSD specification (Shaker Testing)? This is mainly for checking durability/reliability of a component.
