Anti-vibration Design and Structure

For museum grade display cases, robust and stable structure ensure the safety for both exhibited museum objects and visitors as well as museum curators when unconscious or purposed vibration like earthquake come up.

At the very beginning, the robustness and stability of museum grade display cases from WANGDA SHOWCASES will be taken into account as follows:

① The vibration-proof design of display case skeleton is based on dynamics computational model and our precise dynamic calculation.
② The metal skeleton of display cases is constructed and welded with high-intensity rectangular and square steel no less than 2 mm thick.
③ For slim display cases that lack of sufficient stability due to the limited dimensions and structure, they will be invisibly installed with weight increaser at the showcase bottom.
④ Usually freestanding display cases are secured well to the floor by the weight itself.
⑤ Wall showcases are usually mounted to both the wall and floor to acquire enough support.
⑥ In countries with frequent earthquake, seismic-isolation system will be invisibly equipped under baseboard and/or in the lower facility chamber.

Usually the minimal load bearing from lower steel plinth of freestanding museum display cases and tabletop display cases is not less than 150 kg/m² but for larger freestanding and wall display cases or some special display cases, the load bearing of skeleton can be no less than 1000 kg/m².
