A kind of SSI bus turntable angle testing method

Abstract

A method for testing the angle of an SSI bus turntable, the test system: the rotation of a test piece is driven by a motor to rotate a gear set, and the gear set drives an SSI bus encoder to rotate through a coupling, and the SSI bus encoder is used in conjunction with an SSI bus instrument. Take the rotation angle value of the test piece and the information of the number of rotations; and the zero position of the rotary encoder can be calibrated at any position through the SSI bus instrument; the computer can access the data of the instrument and set the parameters through the RS485 bus. The device and the gear set are connected together through a coupling. At the zero position of the test piece, the zero position is set through the control program; the control system: the computer communicates with the PLC through the RS485 bus. The invention has the advantages that the zero point calibration operation at any position of the test system can be completed by the test computer, the zero point calibration at any position can be realized, the work efficiency can be effectively improved, and the system is simple and the cost is low.

Description

technical field [0001] The invention relates to the field of testing systems, in particular to a method for testing the angle of an SSI bus turntable. Background technique [0002] The aero-engine combustor component tester is an important test for the performance of the aero-engine combustor. According to the test requirements, the test galvanic couple needs to be rotated under high temperature and high pressure. The traditional test angle system realizes data collection through a rotary encoder and a parallel port card. The specific test process is to align the test piece with the mechanical zero before the test, and then Correspond the rotary encoder to the mechanical zero position, and connect the zero-aligned test piece with the encoder through the coupling. The key points of system docking ensure that the test piece and the optional encoder do not rotate relatively. The installation is difficult, and at least two people are required. The above staff cooperate. Conte...
