MODE AND ARRANGEMENT FOR DEFINITION OF IMPACT LOAD WITH A LINEAR INDICATOR Russian patent published in 2007 - IPC G01P15/00 

FIELD: the invention refers to measuring technique exactly to the modes and arrangements of the indicators' type for approximate definition of impact load, impulses of power and acceleration.

SUBSTANCE: the mode for definition of impact load with a linear indicator includes installation on a controlled object of a movably fixed magnetic indicative body with known inertial mass definition of the parameters and the fact of relative displacement of the body at the beginning of inertial loads and accelerations. Peculiarity of the arrangement is application of an indicative body with a constant magnet for example in the shape of a washer, its frictional and magnetic contact fastening to a special flat homogenous supporting magnetic surface which is rigidly fixed on the object locating it in a plane near to the plane of action of the expected impact influence on the object with deviation of no more then 24 degrees from it. At that it is necessary to form a frictionally related magnetic pair for which it is necessary to pick up and fix by way of preliminary calculation and experience the mass of the body, its center of heaviness, a friction coefficient and the value of the magnetic field of the constant magnet. The friction power and necessary energy of shift and displacement of the indicative body along the interactive surface is defined taking into consideration the expected threshold impact loadings and displacements. It is necessary to establish the center of the action of the magnet established and the reference initial point around which concentric circumferences are outlined along the body at reference experienced impact influences and according to the facts, footprints and values of linear displacement of the points of the indicative body from the initial reference point it is possible to judge visually about the parameters of real impact influences.

EFFECT: simplification of the mode and means of measuring at low cost of the means implied namely in quality of visual indicators and the simplest signaling devices of impact influences.
