I was given a project to design a test rig for bearings. here is a problem statement:
Design a test rig for a research project to investigate the effect of varying
loads on bearing life, using controlled Zonic servo-hydraulic actuators. The
actuator loads which may be static or dynamic, should be applied onto the
system while the device is driven with a controllable speed electrical
motor. The device must be able to handle a range of radial and thrust
bearings with orthogonal loads (one at a time or two simultaneously).
Applied load, rotational speed and bearing acceleration must be measured
and recorded continuously using a PC and National Instruments data
card.
Detailed finite element frequency analyses should be included in order to
be able to tune the natural frequencies of the system not to coincide with
the frequencies of interest.
I will very gratefull if you can send me any information on this problem
