Dynamics Of A Rotating System: Vibration and out-of-balance forces can be visualised and measured by computer-assisted data acquisition. Static and dynamic balancing is possible for complex rotating shapes. Specially written simulation software is used to compare the theoretical and the actual performance.
The range of equipment allows :
The basic unit consists of a shaft rotating through two bearing blocks and equipped with four discs symmetrically on both sides of the supporting blocks. The system is connected elastically to the base plate via two pairs of flat spring steel beams. Small masses of various values can be attached to each disc to balance or unbalance the rotating system. Rotational movement is given to the system manually.
The test bench is identical, but two of the flexible steel beams supporting the rotating assembly, are fitted with strain gauges. A magnetic proximity detector fitted adjacent to the rotating shaft permits measurement of instantaneous angular position and speed of rotation. These sensors allow computer-based data acquisition.
The apparatus permits all the experimentation but additionally allows the study of the balance of any rotating shape. The two discs closest to the support beams are equipped with rims, allowing the attachment of self-adhesive masses. Furthermore, one of the outer discs can be replaced by a spindle onto which any disc or shape may be attached.
Whichever system is used, it is essential that they are fixed securely to a robust support to maximise the accuracy of the test results.
