The invention discloses a performance parameter test
system of a
silicon oil
damper for a vehicle. The performance parameter test
system comprises a frequency converter, a variable-frequency motor, an elastic
coupling, a torsional oscillation exciting device, a
coupling, a first measuring fluted disc, an adjustable
inertia flywheel, a main shaft, a second measuring fluted disc and a
damper, wherein the torsional oscillation exciting device is connected with a
hydraulic pump station; a first magnetoelectric sensor is arranged above the first measuring fluted disc; a second magnetoelectric sensor is arranged above the second measuring fluted disc; the first and the second magnetoelectric sensors are connected with an NI-PXI6250 acquisition card respectively; and the NI-PXI6250 acquisition cards are connected with a computer. Due to the adoption of the performance parameter test
system, engines of different cylinder numbers can be simulated, the
inertia magnitude of an
inertia disk can be adjusted, and the rotating speed can be adjusted in a
large range; the test system can be used for continually measuring the
instantaneous speed varying quickly and has high distinguishing capability on micro variation of the
instantaneous speed and high responding speed; and due to the adoption of the test system, the cost of real vehicle test is saved, the risks of the real vehicle test are reduced, the function of efficiently measuring the internal performance of the
damper at low cost is realized.
