STAND FOR TESTING COMMUTATIONAL CONTROL APPLIANCES OF THE ELECTRICAL EQUIPMENT OF AN AUTOMOBILE Russian patent published in 2007 - IPC G01M19/00 

FIELD: the invention refers to testing equipment and may be used for investigating reliability and measuring of the electrical and mechanical parameters of the electrical equipment of an automobile particularly for testing the switches under the steering wheel.

SUBSTANCE: the stand has a tested device to whose input the source of input signals is switched and to the output - an electrical loading. The tested device is located in an arrangement for creating a testing environment. To the output of the source of input signals a measuring devices block is switched for measuring the parameters of the input signals, and to the output of the tested device - the measuring devices block for measuring the parameters of the output signals, to the output of the arrangement for creating a testing environment - the measuring devices block for measuring the parameters of the tested environment. The arrangement for controlling the test is interconnected with an automated working post of the investigator and is switched with its outputs to the inputs of the source of input signals of the arrangement for creating testing environment, of the electrical loading and also to each program-controlled testing device and to the measuring devices block for measuring parameters of mechanical controlled impacts which is interconnected with the automated working post. Each of program-controlled manipulator has a reversing motor-reduction gear with a control block connected with a gripping device through traction with a reversing absorber. The number of the manipulators in the set corresponds the number of degrees of freedom of the control appliances of the tested device.

EFFECT: expands functional possibilities and level of automation of the tests.
