FIELD: automatic control of lifts, in particular, quantitative determination of the mass and frictional force of all movable interconnected parts in the sliding doors system relative to the door winds. SUBSTANCE: the door wing is subjected to a training opening run and closing run. In the test section the run is performed with determination of kinematic parameters V<SB>1</SB>,V<SB>2</SB>,S<SB>1</SB> or V<SB>3</SB>,V<SB>4</SB>,S<SB>2</SB>, and first energy balance EB1 or second energy balance EB2 is drawn up. Energy balances EB1, EB2 contain potential energy of the closing weight with a positive or negative sign. Special formulas are given in a combination for numerical determination of the values of dynamic mass Md and mean frictional force E<SB>p</SB> of the sliding doors system. For measurement, storage and processing of kinematic parameters, as well as for computation of numerical values of dynamic mass Md and mean frictional force F<CHF>*@r</CHF> use is made of a microprocessor and a door drive increment transducer. The method is applicable to inertial systems and their physical parameters in general, and it is especially suitable for determination of maximum allowable closing speed V<SB>s</SB><SB>max</SB> of doors of the sliding and turning types. EFFECT: facilitated procedure. 9 cl, 3 dwgd |
