Abstract

The invention provides a low-frequency large-displacement jolting test table with a protection function. The test table comprises a bottom plate, damping air bags, a first fixing plate, guide columns, an adjustable telescoping locking drive rod structure, a liftable buffering adjustment test table structure, a slidable sleeving locking cover structure, a pluggable adsorption protection cover structure, a connecting seat, a damper, a motor seat, a drive motor, a fixing frame, a rotary supporting rod and a height adjustment rotating disc, wherein the lower ends of the damping air bags are connected to the four corners of the upper end of the bottom plate through bolts respectively, and the upper ends of the damping air bags are connected to the four corners of the lower end of the first fixing plate through bolts correspondingly. By arranging the U-shaped base, the rotating pipe, the threaded rod and the inclined T-shaped inserting rod, the locking nut can be loosened in the using process, then the threaded rod is rotated, the length of the threaded rod and the length of the rotating pipe are adjusted, the length of the driving rod can be conveniently adjusted according to needs in the experiment process, and the adjusting work is increased.

Description

technical field [0001] The invention belongs to the technical field of vibration test equipment, and in particular relates to a low-frequency large-displacement vibration test bench with protection function. Background technique [0002] With people's high awareness of product quality, strict quality inspection and all-round environmental adaptability test must be carried out on the product before delivery. In line with the development of the times, the types of products required are increasing, and the types of environmental adaptability tests are also increasing. In the actual test process, low-frequency large-displacement bumping tests and pyrotechnics transportation tests are often encountered. The tests require a displacement of 150 mm to 300 mm and a frequency of 0.5 Hz to 5 Hz. The minimum starting frequency of the electromagnetic vibration test bench is 1Hz, and the maximum frequency can be 3000Hz, but the maximum displacement is 100mm, which cannot meet the test re...
