3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 Sweep scanning

Fixed eccentric moment, the exciter high speed from a low-key process.

3.2 Sweep curve scanningcurve

Frequency exciting means uniform rise from low to high speed process, the workpiece is detected acceleration value point of speed change with the excitation frequency or exciter

Sweep of the curve called the curve, an abbreviated curve, where, a is the acceleration (unit. m/s2); n is exciter speed (unit. r/min).

3.3 Aging time and aging curve agingtime

When the exciter speed stabilized at a certain value, the duration of time is called aging; meantime, reflecting the acceleration of aging time change

Of the curve, the curve is called aging, denoted at the curve, where, a is an acceleration (unit. m/s2), t is the aging time (unit. min).

3.4 Traces trackingcurve

Aging initial frequency acceleration is a fixed value, the control value of the acceleration in the aging process remains the same, the need to constantly adjust the laser
