Paper Abstract

In order to solve the problem of zero displacement momentum of Low-level-light (LLL) sight device, it requitres to provide regulating structure of LLL sight device reticle. Through force analysis of the adjusting screw thread mechanism of reticle under load conditions in shoot test, especially through the calculation of the accumulating value of the circumference torque Tz when the equivalent frictional angle ρ changes, it reveals the zero displacement momentum mechanism of the LLL sight device under the load functions in the shoot test. Applying CMETS005 computer-controlled mulit-environment test of LLL sight device detection systems of this study for practical test, error precision is less than 0.05 mil and the measuring range is greater than 40 mil, which presents that the testing data are reliable and provide theoretical analysis basis for the production of other direct vision sight devices.
