Abstract

The invention discloses a vehicle platform for engine testing, which comprises: a conventional test room located on the upper floor for routine engine test tests, a special test room connected below the conventional test room for engine electromagnetic compatibility tests, and a set For the test transfer device in the special test room, the top plate of the special test room is provided with a connection port connected to the conventional test room. The test adapter device includes a mounting frame assembly vertically arranged in a special test room, a transfer cabinet that is slid up and down connected to the mounting frame assembly, and is used to drive the transfer cabinet to slide up and down on the mounting frame assembly for The connection port enters and exits the drive mechanism of the conventional test room and the special test room. The transfer cabinet is used to transfer and integrate the signal lines of the test and analysis equipment according to the function type and area. The drive mechanism is connected to the control system of the vehicle.

Description

technical field [0001] The invention relates to the field of aero-engine testing devices, in particular, to an engine testing platform. Background technique [0002] The successful development of aero-engines is inseparable from the test work of the bench, and the cost of building a new bench can be as little as several million or even nearly 10 million. Therefore, after a bench is built, we hope that it can meet as many tests as possible. Test environment requirements. [0003] The electromagnetic compatibility test has relatively strict requirements on the test environment. In the prior art, the electromagnetic compatibility test and the conventional test are completed in different platforms. The construction of the platform is expensive and the test operation is troublesome. There is an independent signal line system, and all signal lines in the signal line system are individually numbered, including temperature, pressure, vibration, data acquisition and other signal lin...
