TWO-COORDINATED FRICTION MACHINE

FIELD: test equipment. ^ SUBSTANCE: machine can be used for testing materials and lubricant matters for complicated trajectories relatively movement of interacting friction pairs. Two-coordinate friction machine has base, sample's holder, two-coordinate drive, counter-body's holder, loading mechanism interacting counter-body, two-component force detector connected with counter-body's holder, program control system and friction force main vector instant value automated estimation system. Two-coordinate drive is made in form of two independent movable carriages which move at mutual-perpendicular directions. Holder of flat sample is disposed onto one carriage and counter-body's holder, loading mechanism interacting with holder and two-component force detector connected with holder of counter-body are disposed on the other carriage. Program control system is made in form of control computer connected with independent control modules and with electric engines through matching unit. Electric engines drive two-coordinated drive into motion to provide movement of indicator which interacts with working surface of sample along continuous nonlinear two-dimensional trajectory. ^ EFFECT: widened functional abilities; improved precision; better truth of result. ^ 4 cl, 1 dwg
