A measuring instrument for compression stress relaxation

摘要

the The present invention, such as oil and fluid (hydraulic fluid) elastomer (elastomer) filled material in the state the test piece is accurately measured by the compressive stress relaxation resistance of the device to display to the outside. ; compression stress relaxation resistance measuring device of the invention has a housing that forms a space of a predetermined size therein, and (20) and a test piece is placed in the housing (20) (M) and, with the test piece (M) pressing the pressing plate 30, the press plate 30 to force the holder to press the test piece (M) 40, the press plate 30, the space block for limiting the extent to press the test piece (M) (50) and the test pieces for measuring the stress applied to the load cell (M) (60) and the specimen configuration, such as the stress applied to the load cell 60 is passed to a transmission member 70 and the load cell 60 and is provided between the housing 20, the heat insulating member to prevent heat transfer (80) to (M) It is. According to the present invention having the above configuration, there is a compressive stress, a more accurate measurement becomes possible advantage of the relaxation resistance.
