Shock input velocity

WebV = Linear velocity of impact at the shock absorber (ft/sec.) V R = Rotational velocity of impact (radians/sec.) at the shock absorber F = Output force from shock absorber at impact (lb.) F D = Drive force (lb.) H = Vertical height (in.) S = Shock absorber stroke (in.) I = Moment of inertia (lb-ft-sec. 2) T = Time (sec.) WebThe initial velocity is calculated using a familiar physics formula where the change in kinetic energy is equal to the change in potential energy due to gravity. Assume that the object is dropped from rest. The initial velocity as it strikes the ground is (2.1) The equation of motion is (2.2) Or equivalently (2.3) The peak displacement is (2.4)

WebWhen shock spectra are plotted in terms of velocity, there is no need to consider a wide range of velocity values, which simplifies the presentation. Virtually nothing can withstand a shock motion that generates shock spectrum velocities of 1000 ips, and even a shock with spectrum velocities of 200 ips is a very severe shock. WebA shock absorber is a device which converts mechanical energy into thermal energy. The energy transformation occurs as the shock absorber’s fluid medium is forced through orifices at high velocities. Selecting a shock absorber is not difficult if you follow the …
