Mechanical vibration - Coursework Example

The European Standards set out in ISO 2631-1 provide a criterion through which vibrations can be evaluated, analysed, and monitored. The purpose of this standard is to protect employees from unnecessary and harmful modes of vibration in the work place. The BS EN 14253:2003+A1:2007 is an essential document that aids in calculating vibration doses an employee gets when using vibration equipment. Through the calculations, the employee is assured of his health as well as good practices for vibratory equipment (Finucane, 2006).

The document contains methods of measuring and establishing the daily exposure of vibration. This can then be compared to the required daily dosage units for the purpose of employee safety and health. EN 30326-1-this norm of reference reflects mechanical vibration, with a detail outline of laboratory methods used to evaluate vehicle seat vibration. Its Part I outlines the ISO 103236-1:1992 for the basic requirements. The evaluation of exposure to vibration by employees is based on two principles; the frequency-weighted acceleration and the total duration of exposure to vibration per day.

Frequency-weighted acceleration is expressed in m/s², reported as Root Mean Square (RMS) value. On the other hand, the total exposure to vibration per day is denoted as Ti with the denotation i reflecting the particular operation. Using the two principle guidelines for evaluation of quantities for vibration exposure, exposure profile defines the dosage of vibration an employee is exposed to, using the value A(8). This requires accurate measurement of the sources of vibration on a frequent basis.

The exposure profile also states measurements made in the context of daily vibration exposure. Since the operations are identified, important factors must be considered. These are; One of the sources of whole-body vibration is a travelling car. A comparative assessment was done on whole-body vibration exposure. The car
