For all kinds of products, in the production, transport sales are to go through to reach the hands of the users, so study the performance of the transport process is very necessary.Usually requires the use of simulated transport test stand , the test bench, as the name as is used to simulate the transport process of situation and required testing of specimen tested in this environment.

Simulate the transport station test procedure is also very simple, first of all we need the product of the surface of the packaging placed on the vibration table starts vibrating machine, making it the lowest frequency of the machine vibration, The full amplitude displacement to one inch (25 mg), to maintain a one-inch (25 mg) fixed displacement, slow increase in the frequency (speed) of the vibration table until the the packaging left shaking table surface.

Secondly, keeping the machine vibration frequency obtained in the above step, a metal foil is not mobile in the packaged goods the longest side of the bottom and between the vibrating table can be intermittently?, Maintaining this frequency, to proceed with the next step, if it is, gradually increasing frequency until it reaches the requirement of the step 5, and then maintaining that the new frequency before the start of the vibration test using the above portion of the formula and obtained in the previous step CPM or Hz to determine test time.Start timing vibration test time.

Finally, to confirm whether or not to use a vertical linear motion of the vibration system?If not, the next step, the vibration half complete stop after the vibration test, and then complete the appropriate steps are listed in the following table: If a single 90 degree horizontal rotation is: then following horizontal rotation; may be a test sample on the countertop 90 degrees impossible, due to the packaging size or stability of the test sample on the countertop 180 degrees.Start the vibration system, continues to set the frequency of vibration test.The metal foil is not packaged goods the longest side of the bottom and between the vibrating table can be intermittently moved?If not, gradually increasing frequency until it reaches the requirements, the completion time of vibration.If allowed, the test does not change the location or condition of packaging existing condition or product and, in any case, inspection and any visible damage of the packaged goods, vibration test ends.

Addition to covering analog transport vibration table, slant impact test rig package squeeze test, the the Bond production of products endures, office furniture detect test test equipment , test instruments upholstered furniture, sofas endurance testing machine and sofa detection equipment the mattress durability testing machine and mattress comprehensive performance test equipment, furniture, fatigue testing machine, office furniture service life testing, office furniture, hydrostatic testing, multi-functional wheelchair test test instruments, welcome to order!
