Cheap PriceList for Bottle Cap Torque Tester - C0044 – Cornell Type Tester – Drick

The Cornell Type Tester has been designed and manufactured fortesting and evaluating

of Innerspring and Boxspring mattresses.

There are several different methods used for the evaluation of innersprings and boxsprings,

testing for measurements regarding firmness, firmness retention, durability, effect of impact

etc.

The Cornell Type Tester is used to test the long term capacity of bedding to resist cyclic

loading. The machine consists of a double hemispherical ram head on a manually adjustable

shaft. A load cell is located on the ram head to measure the force being applied to the mattress.

The shaft is connected to an adjustable eccentric which is rotated by an electric motor at

up to 160 cycles per minute, variable.

The bedding is located below the ram, and the eccentric and shaft position adjusted so that

the maximum load of 1025N and the minimum load of 22N is applied when the eccentric is

rotated to the lowest and highest positions respectively. A position transducer is located so

the position of the ram head can be measured automatically.

The eccentric is then rotated slowly, raising and lowering the ram head so that the load/

position data can be recorded for a few cycles. The mattress firmness is calculated from

the load readings between 75mm and 100mm respectively.

This procedure is performed at the start of the test and the subsequently at the end of

each of seven stages. These stages are reached when 200, 6,000, 12,500, 25,000, 50,000,

75,000 and 100,000 cycles have been completed at 160 cycles per minute. The duration

of the cyclic testing will take nearly 10.5 hours, simulating 10 years of mattress use.

At the end of each stage, the position of the ram head is noted when a load of 22N is applied

to the mattress. A change from the previous static reading is referred to as a dimple and this

is recorded.

An operator prompting computer program measures both the load and ram head position from

the two transducers throughout the total test stages and produces a full test report upon completion.
