Industrial Vibration Table : Perfect for testing the resistance of materials to vibrations, widely used in automotive, electronics, and construction industries.
Most consumer products undergo vibration testing, the most common form being package testing. Package testing is designed to simulate a product's journey from when it´s boxed at the factory until it is transported to the customer's home.
One such package testing system was designed to enable the customer to simultaneously test two plasma screen television sets weighing 85 kg each in their transport boxes. The tests were designed to reproduce the effects of transport on the televisions and allowed for the optimisation of the packaging design, and savings on materials like polystyrene packaging. The customer used a combination of sine tests, typically <5 mm peak-to-peak in the 5 - 20 Hz range, and Random tests <1.5 g up to 200 Hz. The system combines a rigidly mounted standard shaker with specially designed steel trunnions and a magnesium head expander measuring 1.8 m x 2.2 m and supported by a loadbearing platform. The basic over-turning apability of the load-bearing platform is 5 kNm, and it is restrained by guide shafts which are part of the steel work. Airbags located underneath the trunnions isolate the vibration. Pnuematic isolation is incorporated to prevent unwanted vibration being transmitted into the building. Once on site, the head expander is positioned at floor level, allowing the
loading and unloading of payloads by pallet truck for the quick turnaround of large test articles. A remotely operated safety mechanism to lock and unlock the LBP had to be designed to allow access to the shaker.
