Abstract

The invention discloses a device and a test method for measuring the adhesion force between ice and objects, belonging to the field of mechanical measuring instruments. The invention includes a cooling device, a force measuring device and a feed driving device. The measuring probe extends into the cooling box to touch the ice adhering to the sample to be tested, and the adhesive force between the ice and the sample to be tested is measured by a force gauge. During the working process, the ice adhered to the sample to be tested is placed in the cooling box, and the constant temperature environment can be maintained during the process of measuring the adhesion force; the feed speed is adjusted by controlling and adjusting the geared motor connected to the linear workbench, Feed speed is smooth, shocks are reduced and adhesion measurements are more accurate.

The method of testing of the device of adhesion between a kind of above-mentioned measurement ice and object is characterized in that realizing as follows:

Step 1: will ice 1 and place and be fixed on the sample tray 3 with testing sample 2, sample tray 3 is fixed on the lifting table 4;

Step 2: the fixedly connected good lifting table 4 of step 1 is inserted in the cooling tank 6 with testing sample 2 together with the ice 1 of placing and being fixed on the sample tray 3, by lifting table adjusting screw(rod) 5 lifting table 4 is adjusted to the height concordant with measuring sonde 7, again with the adjustment in the cooling tank 6 to measuring temperature;

Step 3: will be fixed on by the device for measuring force that measuring sonde 7, push rod 8 and dynamometer 9 connect to form on the dynamometer pallet 10 of fixedlying connected with straight line worktable 11, the reducing motor 13 that regulating and controlling is connected with straight line worktable 11 by shaft coupling 12, and then regulate speed of feed;

Step 4: measuring sonde 7 stretches into and touches the ice 1 that sticks on the testing sample 2 in the cooling tank 6, measures the adhesion of 2 of ice 1 and testing samples by dynamometer 9.

The invention has the beneficial effects as follows: the ice that sticks on the testing sample places cooling tank, can keep isoperibol in the process of measuring adhesion; Regulate speed of feed by regulating and controlling with the reducing motor that the straight line worktable is connected, speed of feed is steady, impacts lessly, and the adhesion measurement result is more accurate.
