Displacement 1 Sinusoidal Input 2 4 Time Sine Wave Displacement Input Sinusoid, most Common Input form for Shock Testing Displacement = X sin (�t) Velocity = V = X � cos (� t) Where w = 2 * � * Freq. Peak Velocity = X * � 3 1 Velocity 1 2 3 Time Corresponding Velocity Input Typically test at a given stroke and vary frequency. <strong>Suspension</strong> normally respondes at forcing freq. and natural frequencies. So should we test at bounce and wheel hop freq.? 4 1
