Abstract

This invention relates to a measurement technique. The purpose of the invention is to enhance the functionality by measuring axial overloads acting alternately in opposite directions. Under the action of overload, the striker 6 under the action of its inertia compresses the spring 8 and crushes the tapered part of the kresherny column 3, in this case the second drummer 7 abuts against the shoulders of the housing 1. The compression of the spring 9 and the contact of the column 5 occurs when the overload direction changes by the inertial force of two drummers 6.7 acting together. At this time, the spring 8 is disconnected by means of the washer 10 to eliminate the effect on the joint movement of the strikers. 1 il.

The invention relates to a measurement technique of pre-papaznapio for recording linear overloads from a BOZ effect on an object of shock loads,

The purpose of the invention is to create a measuring transducer, whose construction allows to register changes in time overloads acting alternately in opposite directions during one object's stroke5, for example, measuring the overload curve according to the law of two half-sine waves, alternate times when the time is overload in one direction (acceleration of the object) is less than the opposite (inhibition), or vice versa.

The drawing shows the sensitive element of one of the cells of the proposed converter.

The sensing element contains cell housing 1, plugs 2. With sockets for kreshernyh little tables 3 ,, plugs h with sockets, sub-pillar 5 columns, drummers 6 and 7 with strikers, pins; keys 8 and 9, washer 10,

; The transducer sensing element operates in the following way.

 Under the action of an overload, directed from above to ipiz by the drummer's pattern, it is under the influence of its yiners and squeezes the cone part of the kresher column 3 in this case. In this case, the second impact 7 rests on the shoulders of the housing 1, the spring 9 is compressed and see column 5 when changing the direction of the overload action by the inertial force of the two strikers 6 and 7, acting together. At this time, the rod 8 is turned off with the help of a washer to eliminate the effect on the joint shaft of the drummer. The stroke length of a drummer is determined by the amount of compression of the springs and compression of the conical part of the cross column, and the nature of the movement is changed by adjusting the initial gap. between striker striker and the top of the cone of kreshernogo column.

The order of counting overloads for each cell by the proposed converter does not differ from the one adopted in the prototype.

The design of the proposed measuring transducer, in which the kresher columns are used in combination with springs and impactors, fixing the action of overloads directed alternately in opposite directions, differs from the selected prototype, as it allows to register inertial overloads of high intensity with time during acceleration of the object and braking.

The design of the transducer is intended for use in research and development institutions, MO and industrial test sites for checking the strength impact characteristics of equipment and weapons when tested on impact stands, projectiles when firing from gun mounts and interacting with equipment -and.
