Reproducing Vibrations And Shocks

The vibrator reproduces the vibrations and shocks to which an object is subjected during shipment. A variety of movements, including high frequency and low amplitude vibrations, is simulated.

The vibrator has a table 10, spring and shock mounted on support 11, for movement vertically and horizontally in two directions at right angles. The tension of springs 12 is adjustable so that the spring recovery rate, when table 10 is moved vertically and released, is similar to the recovery motion of the transporting vehicle. Table 10 is also mounted on a plurality of spring and shock absorber assemblies 13 to control the vibration of the table after the exciting force is released. Eight electromagnets 15 are carried by support 11 and project toward the table 10 to be engageable with metal plates.

The article on page 29 of this issue describes a tape recorder for vibrations and shocks received by an object being transported. Such recorder produces three tape recordings of movement in three mutually perpendicular directions. The magnetic tapes are used to control the current supplied to the electromagnets 15. An object, similar to the one for which recordings are made, is placed on table 10. The latter is then vibrated to subject the object to vibrations and shocks which are identical in frequency and amplitude to those recorded during actual shipment.
