SU596829A1 - Precision instrument shock-absorbing device - Google Patents

Description

It is attached to the object, the azimuth turns of which need to be measured. Works damping device as follows. The force P acting on the base 1 of the shock-absorbing device during shock overloads is decomposed into components along the three coordinate axes Рдг Р Р Сія Р, acts on the X axis and perceived by the platform 3. The force Pj acts on the OS axis and is perceived by the intermediate platform 4. Pj force acts along the Of axis and is perceived by the instrument platform 6. Consider the operation of the intermediate platform 3 when the force PJ acts on the base 1 (Fig. 2). If the base I, on which the intermediate platform 3 is fixed through the springs 2, starts to move with acceleration under the force of the PI force, then an inertial force arises applied to the intermediate platform 3 ,. which deforms the flat springs 2 in the direction of least stiffness, and when the rigidity of the intermediate platform 3 is high, the nepeMemaTSCf will be progressive. As in {ah & The seventh time intermediate yatforya 3 is lagging in motion from the base of i, V to Sssa, it moves with acceleration Less than acceleration ooh: ns aa; NI9, with, nno. springs 2 reduce the shock load - the OX axis on the intermediate platform 3, and with it on the intermediate plate Form 4 and the instrument platform 6 rib compared to base 1 by an amount equal to the ratio of the base acceleration to the acceleration Intermediate platform

tPvi.f Similarly, the intermediate platform 4 works under the action of the force Рl along the OS axis and the instrument platform under the action of the force Р along the О axis. The presence of elastic elements in the form of flat sheet springs eliminates the error caused by the angular turns of the instrument platform after the shock loads, and simplifies the design of the device. The invention allows to expand the range of shock loads at which the precision can work, ion devices. Claims of the invention / Damping device for precision instruments, comprising a base connected to the instrument platform via elastic elements, which is due to the fact that, in order to eliminate angular turns of the shock absorbers of precision instruments relative to the base and to protect against shock overloads in three planes, two intermediate platforms are inserted in it, located parallel to the base ff of the orthogonal instrument platform, bitingly connected one through the other to the base and the instrument platform by elastic elements Tammy, vypolnenny1ua1 in yide ploskihli STOV / springs arranged in mutually edeh claim open aikul polar planes.
