FIELD: testing technology. ^ SUBSTANCE: proposed testing stand includes base (bed frame), working horizontal platform, supports, vibration exciters, hydraulic drives and electric control and measurement system provided with motion and acceleration sensors. Stand is also provided with frame which is parallel relative to working platform and L-shaped rigid levers which are articulated on base by their middle points; horizontal arms of levers are connected with working platform by means of rigid supports and their vertical arms are articulated with rigid frame which is articulated in its turn with vibration exciter. ^ EFFECT: low cost; enhanced efficiency. ^ 2 dwg |
