STAND FOR ACOUSTIC TESTING OF ELECTRO-HYDRAULIC APPARATUS INTEGRATED WITH HYDRAULIC FLUID TANKS OF VEHICLES Russian patent published in 2022 - IPC G01M15/02 G01H17/00 

FIELD: testing.

SUBSTANCE: stand relates to supporting means for studies of the acoustic noise of electro-hydraulic units built into hydraulic fluid tanks of vehicles. Stand comprises recording and testing equipment, a power source, measuring microphones, a suspension, and a parallelepiped-shaped frame including racks and bolts. The suspension is made in the form of a netted pocket with the fixed on the bolts of the frame and the netting formed so as to be able to retain various tanks from the number of tanks integrated in the vehicle with the tested electro-hydraulic apparatus in the space between the frame elements. The netting of the pocket is formed with mutually intersecting shock-absorbing cords connected so as not to form knots at the intersection points thereof. The stand is equipped with a pumping unit and a pumped fluid storage configured to store the fluid provided for by the test rules, as well as filling the tank with the fluid to the level set by the test rules indirectly by the pumping unit, wherein the stand is equipped with a meter and an indicator of the volume of fluid contained in the tank.

EFFECT: provided various acoustic tests of any electro-hydraulic apparatus built into the tanks of vehicles.
