Horizontal Vibration an overview ScienceDirect Topics

24-02-2011· However, horizontal vibrations do occur in addition to vertically polarized shear waves emitted along the shaft of the compaction probe. The horizontal vibrations are caused by the friction between the compaction probe and the soil, and they generate horizontal stress pulses directed away from the probe during the downward movement of the probe.

The effects of vertical and horizontal vibrations on the

01-03-1994· Vertical and horizontal vibrations of a 100kg human have been investigated. A new mechanical model has been developed, and an analogous electric simulation has been carried out, which in turn has been analysed by using computer software (micro-cap ii).The vibration force comes from (a) hand, (b) seat and (c) a combination of the two.

1X high horizontal vibration at motor AMP Maintenance

It is symptom of Misalignment. However, if the horizontal is higher than vertical, you have to think about structure looseness. You should trend and monitor the vibration by time, if it rise, shut-down your machine, check and correct alignment, check and correct soft-foot, check and tight all bolts off system. Good luck.

and consistent horizontal vibration performance. Cooling Shakers consume significant elec-trical power which is converted to heat. Cooling of field coils and armature coils is mandatory in an electrodynamic vibration system. Shakers up to 15,000 lbf are typi-cally air-cooled, while high force shakers (20,000 lbf and above) are liq-uid-cooled. Air-

The Effect of Relative Humidity and Roughness on the

The direction of vibration is horizontal. Horizontal vibration is created along (longitudinal direction) and perpendicular (transverse direction) to the sliding direction. The experimental setup has the facility to vary the amplitudes and frequencies of vibration while velocity of vibration is kept constant.

VIBRATION SPECTRUM ANALYSIS ALPHAPEDIA

VELOCITY = Vibration velocity is measured in peak units such as inches per second (ips) or millimeters per second (mm/s). Another way to see speed is distance per time or the amount of movement of the machine each second in three important directions at all major bearing points (AXIAL, VERTICAL, HORIZONTAL).
