 The Lansmont Model 122 Shock Test System is available in two configurations: Standard Duty and Heavyweight versions. Both versions can accommodate test items with footprint dimensions up to 48 inches square (122 cm x 122 cm). While the Standard Duty version can handle a maximum payload of 1,000 lbs. (454 kg), the Heavyweight version more than doubles the maximum payload to 2,500 lbs. (1,134 kg). The Model 122 can perform a wide variety of shock tests in either configuration to a maximum acceleration of 600 g. The Model 122 consists of a one-piece welded aluminum shock table that is precisely guided by two solid steel, chrome-plated guide rods. The two guide rods are rigidly attached to a massive, isolated steel base that helps to attenuate any shock energy that would otherwise be transmitted to the surrounding building through the laboratory floor. Also mounted to the steel base are four Damage Boundary Programmers, which allows the operator to generate both half sine and trapezoidal shock pulse waveforms. The Model 122
shock tester is equipped standard with Lansmont's NEW TouchTest Shock II Controls.
At the start of a shock test an electric hoist raises the shock table until it reaches the programmed drop height, which was easily preset by the operator using the NEW TouchTest Shock II Controls. Once the operator safely initiates the drop sequence, the lifting hook swings clear of the shock table and the two redundant brakes systems release allowing the shock table to free fall. The shock table impacts the Damage Boundary Programmer, creating the desired shock pulse waveform. As the shock table rebounds the hydropneumatic brakes reengage to prevent any secondary impacts.
