Experimental device for acquire granular material suppression power and mould wall frictional force

Experimental device for acquire granular material suppression power and mould wall frictional force belongs to the experimental mechanics field, and its structure includes stamping, bottom punch, bed die and granular material pressed compact, last stamping on install a pressure sensor, the bottom punch on install the 2nd pressure sensor, a pressure sensor and the 2nd pressure sensor pass through the changer and connect the record appearance. The granular material pressed compact carries out the in -process suppressed, and the pressure signal that a pressure sensor obtained is for on the F, and the pressure signal that the 2nd pressure sensor obtained is for under the F, the changer with F go up convert 4 -20mA to with F pressure signal down standard signal with standard signal transmits for the record appearance, the record appearance go up F and F under real -time recording. The utility model is used for coefficient of friction in the demarcation DEM method between granule and the mould wall.
