What is the purpose of drop testing? Drop testing mimics the shipping and distribution .The test program was arranged to examine mechanical components individually at first and then progressively within complete subsystems. Wind tunnel work was begun early so that the stabilization configuration could be developed in time for full-scale air drop testing. Recovery parachute experiments initiated the hardware field test phase.

This fixture has a T-slotted sled that allows the substrate clamps, which secure the substrate to the sled, to adjust to a . The drop sled test fixture shown in Figure 3 was constructed. The actual sled, which holds the wheel, consists of a steel frame, to which an axle and weights are bolted, and slides on four linear bearings on rails attached to the inside of a fixed gantry. . commensurate with a 95 kg rider on a 15 kg bike with 40% front and 60% rear weight .
The impact test machine is designed to generate a shock for different loading modes (traction, shear and mixed-mode) on the specimen. In order to respect these requirements, as described in Fig. 3, the impact test rig is based on two principles the Beevers and Ellis drop weight test machine [4] and the modified Arcan fixture proposed.Beevers and Ellis machine .4 MAIN TEST PROGRAMME 4.1 Sled Acceleration 4.1.1 The pulse performed on the sled facility shall be at least as severe as the representative MPDB test pulse, measured at the struck side B-pillar, and will be assessed according to the method detailed in Section 5. 4.2 Steering column adjustment

TruMotion Acceleration Test Systems When transport vehicles accelerate, turn or brake, the resulting low-frequency accelerations can cause unit loads to shift. Due to both safety issues and potential product damage/waste, regulatory bodies are requiring testing that’s closer to reality – assuring safe and stable unit load integrity!Figure 5 shows one such example. In the foreground is a standard Boeing fixture. In the background is a specially designed fixture, capable of testing specimens either 6 in. or 10.5 in. tall and 4 in., 8.5 in., or 10.5 in. wide. Another special CAI fixture is shown in Figs. 6 and 7. This fixture is designed to test tall, narrow specimens. The National Highway Traffic Safety Administration (NHTSA) has utilized a two part sled fixture to evaluate a near side test protocol for child restraint systems (CRS). The test was designed to impact the CRS with a fixed door at nearly 20 mph. This paper examines the affects of various fixture parameters on the acceleration and velocity profiles of the two part system .Equipped with a direct reading of speed, automatic recovery and positioning system of the weight.

Therefore to mitigate this risk i want to devise a drop test that will mimic the shock loadings seen during the vibration test. I know that the max shock during the test is 50g for 10ms and the weight of the object is 0.05 Kg. Now all i need is a height, but the more i look into it the more it starts to look like einsteins style of work .Weight: 3,5 kg (for I-Beam, spacer and W-Beam) Lenght: 2 m: Interface: Designed according to South Tyrolean guard rail .
