Embodiment 1

[0064] Take the measurement of the adhesion force between the biological sample Drosophila and polished paper with a particle size of 5 μm as an example:

[0065] [1] Turn on the computer 8 to warm up for ten minutes;

[0066] [2] Open the dodge door 102 of the openable transparent box body 1, and rotate the second lifting adjustment screw 421 of the second lifting device of the force measuring sensor 4 to adjust the height of the antenna pull rod 41 to the position ratio of the camera 2 The height of the left end magnetic sheet 411 of the antenna pull rod 41 is 5mm lower; the first lifting adjustment screw 321 of the first elevating device of the rotating rotatable stage 3 makes the height of the object-carrying round table 31 with rolling bearings lower than that of the antenna pull rod 41. 8cm lower;

[0067] [3] According to the required test accuracy of 0.2 mg for the adhesion between the biological sample fruit fly and the polishing paper, the required length of the ant...

Embodiment 2

[0079] Measuring the adhesion force between the biological sample beetle and the sandpaper surface with a particle size of 40 μm, the basic steps are the same as in Example 1, except that:

[0080]The selected biological sample is a beetle, and the object is sandpaper with a particle size of 40 μm. According to the test accuracy of the adhesion force between the biological sample beetle and the sandpaper is 1.5 mg, the required value of the antenna pull rod 41 corresponding to this accuracy is found in Table 1. The length is 20cm, the measured L p = 8cm, L d = 8cm, M d = 10.7 mg, the injection volume p=5 mg injected into the liquid reservoir each time, the total number of mouse clicks N=57, calculate the adhesion value F of the biological sample beetle and the sandpaper at this moment by the computer 8 through the formula a =2.69mN, test 20 same kind of biological sample beetles, the 20 data obtained are processed through computer 8 data processing software, obtain the adhes...

Description

technical field [0001] The invention belongs to the field of mechanical measuring instruments, and relates to a force measuring device and a testing method for measuring the adhesion force between living organisms and objects. Background technique [0002] Measuring technology has always been considered as an effective means to achieve breakthroughs in scientific research and production. Therefore, the development of measurement technology plays a vital role in the progress of scientific research and production. At present, the value of the adhesion force between objects is often obtained through probe atomic force microscopy (AFM) and mechanical sensor instruments. However, the probe atomic force microscope cannot take living organisms as the measurement object, and the selection of the test object has great limitations, and according to the different test purposes, it is often necessary to change some structures to achieve it, and the cost is relatively high; The sample ...
