Crystal Instruments recently updated the Vibration Utilities app (available for iOS and Android). This app supports features assisting in calculations related to the shock and vibration testing industry.

vibration utilities app for shock and vibration testing

Unit Conversion
Convert common units (metric and imperial) such as acceleration, velocity, displacement, voltage, force, stress, etc.

Sine Motion
Input two values to calculate the remaining Acceleration/Velocity/Displacement (AVD) values for a sinusoidal motion. The available values are frequency, acceleration, velocity, and displacement.

Shock Calculator
Input shock parameters to calculate the AVD values of a shock pulse.

Random Calculator: PSD to RMS
Input three values to calculate the remaining value for a constant Random Power Spectral Density (PSD). The available values are min frequency, max frequency, amplitude (Engineering Units (EU)2/Hz), and RMS (EU).

Log Gain Calculator
Calculate the gain between an input (reference) value and an output value, in terms of ratio or dB.
