Abstract
A testing apparatus, in particular a tire testing apparatus, includes a testing chamber, a pressure loading unit for changing the pressure in the testing chamber and at least one measuring head for measuring a measurement object arranged in the testing chamber at different pressure values produced by the pressure loading unit. It is provided here that, for changing the pressure in the testing chamber, the pressure loading unit changes the volume of the testing chamber while excluding air from the surroundings.
Claims16
A testing apparatus for testing a tire, the testing apparatus comprising:
- a testing chamber formed by a plurality of wall elements, the wall elements being configured such that a tire can be arranged as a measurement object to be tested inside the testing chamber and such that the tire is surrounded by the plurality of wall elements for testing;
- a pressure loading unit configured to change a pressure in the testing chamber;
- and
- at least one measuring head configured to measure a measurement object arranged in the testing chamber at different pressure values produced by the pressure loading unit,
- wherein, to change the pressure in the testing chamber, the pressure loading unit changes the volume of the testing chamber while excluding air from the surroundings,
- wherein at least one of the plurality of wall elements of the testing chamber is a movable wall element and forms a part of the pressure loading unit,
- wherein the movable wall element is movable with respect to a remainder of a testing chamber structure, and
- wherein the pressure loading unit is configured such that the volume of the testing chamber is changed by a movement of the movable wall element with respect to the remainder of the testing chamber structure.
A method for testing a measurement object by a testing apparatus, the testing apparatus including a testing chamber, a pressure loading unit configured to change a pressure in the testing chamber, and at least one measuring head configured to measure a measurement object arranged in the testing chamber at different pressure values produced by the pressure loading unit, the method comprising:
- introducing a tire as the measurement object into the testing chamber of the testing apparatus, the testing chamber being formed by a plurality of wall elements, the wall elements being configured such that the tire is arranged inside the testing chamber and such that the tire is surrounded by the plurality of wall elements for testing;
- changing the pressure in the testing chamber by changing a volume of the testing chamber while excluding air from the surroundings, wherein at least one of the plurality of wall elements of the testing chamber is a movable wall element and forms a part of the pressure loading unit, and wherein the volume of the testing chamber is changed by a movement of the movable wall element with respect to the remainder of the testing chamber structure;
- and
- measuring the measurement object arranged in the testing chamber at different pressure values.
