The obtained results of measurements of vibrations of the roller of the folding machine at the velocity equal to 90 m/min are shown in Fig. 6. Renewal of the roller of the folding machine has led to the change of the measured displacements. The displacements of the roller reduced from 30 μm before renewal to 15 μm after renewal.

VIBRATION CHARACTERISTICS OF TAPERED ROLLER

1996-2-22  An investigation was carried out to explain the vibrations of tapered roller bearings. The vibrations of four types of normal tapered roller bearings were studied. The test bearings were operated under several rotational speeds and axial loads. The radial and the axial vibrations on the outer ring of each test bearing were detected by an accelerometer. The vibrations were examined by using a FFT

Effects of profiling elastic press roller on seedbed

2016-9-1  The vibrations can enhance the soil compaction. Meanwhile, the rib structure of the roller surface can press into the soil under the load action, reducing the slip ratio of the roller in the working process (Jia et al., 2015b). One conventional press roller (CPR) with 300 mm diameter and 2.6 kg weight was used in this experiment. The CPR will generate pressure as soon as it is in contact with the soil

Vibration Analysis and Modeling of an Off-Road

In order to evaluate the ride comfort of the vibratory roller with the different cab’s isolation mounts, a three-dimensional nonlinear dynamic model is established. The power spectral density (PSD) and the weighted root mean square (RMS) of acceleration responses of the vertical driver’s seat, cab’s pitch, and roll vibrations are chosen as objective functions in the low-frequency range.
