24、(E) 4 Introduction The aim of this European Standard is to deal with vibration as a hazard and to provide methods for the measure- ment and reduction of vibration emission transmitted to the whole body of drivers of GSE, when driving. For deter- mining whole body vibrations under stationary operatin
25、g conditions and hand-arm vibrations EN 1032:2003 is used. It is intended that the results obtained can also be used to compare GSE of the same category or a given GSE when equipped with different seats or tyres, etc. Fitting different seats, changing the tyre specification, etc. can lead to differe
26、nt vibration values. Due to the specific operation of GSE, however, EN 1032:2003 cannot be applied directly for whole body vibration under driving condi- tions, and therefore, the preparation of this European Standard for GSE has become necessary. This European Standard cannot be used for field meas
27、urements to determine the daily exposure of the driver to vibration. This European Standard is a Type C standard as stated in !EN ISO 12100“. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi- cated in the scope of this document. When provi
28、sions of this type C standard are different from those which are stated in type A or B standards, the pro- visions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

30、E, when driving for purposes of type evaluation, declaration and methods of verifying vibration emission. The test results are not applicable to the determination of whole body vibration exposure of persons. !This European Standard is intended to be used in conjunction with the other parts of EN 191

37、ssion is a significant hazard, which shall be reduced to the lowest level taking into account the techni- cal progress and the available technical measures for vibration control. The main source causing whole body vibration is the interaction between the machine and the surface of the ground. Measur
38、es for reducing the vibrations can be: pneumatic instead of solid tyres; suspension; vibration isolated cabin; suspension seat; shock absorbers. After taking at design and manufacturing all possible general technical measures for vibration reduction the instruc- tion handbook shall, when appropriate
39、, identify any additional vibration reduction measures, which can be taken by the user. Furthermore, it shall, where appropriate, recommend organisational measures such as the use of low- vibration operating modes, and/or limited time of operation. 5 Quantities to be measured The quantities to be me
40、asured are as follows: a)The root mean square (r.m.s.) acceleration )(wza of whole body vertical frequency weighted vibration in accordance with EN 1032:2003. Measurements shall be made in the vertical (z) direction. If there are substantial vibration components as defined in EN 1032:2003, Clause 6
41、in the horizontal directions, the summation aw shall be measured, calculated and declared according to EN 1032:2003. Standing driver wzF a Mean value of n root-mean-square frequency weighted vertical acceleration values of a valid test series measured on the floor of the driving position with one st
42、anding driver. Seated driver wzS a Average of acceleration mean values obtained for each of the two drivers for a valid test series measured on the seat base under the seated driver. NOTE 1 The symbols F and S designate “Floor” and “Seat”; b) The mean GSE speed when travelling on the test track. Thi
43、s may be determined from the time taken to drive along the test track or by means of the measuring instruments specified in 6.5; BS EN 1915-3:2004+A1:2009 ? EN 1915-3:2004+A1:2009 (E) 7 c) Pneumatic tyre pressures (see also 8.2.2); d) Ambient air temperature. NOTE 2 If a standard vehicle is used for
44、 the GSE, and declaration data for vibration are given by the manufacturer, these values may form the basis for the vibration declaration for the GSE provided that the application of the standard chassis to the use as airport GSE does not imply changes in design or construction which affect the vibr
45、ation characteristics. 6 Instrumentation 6.1 General The specifications for the instrumentation given in EN 1032:2003 apply. 6.2 Transducers General requirements for mounting of vibration transducers are given in 7.2 of EN 1032:2003. On a seat pan, the transducer shall be mounted in a semi rigid dis
46、c as described in 7.2 of EN 1032:2003. On the floor, the transducer shall be firmly fixed to rigid parts of the GSE, e.g. by means of a magnet or adhesive, etc. NOTE In the case of stand on GSE, it is convenient to mount the transducers on a light rigid plate upon which the driver can place both fee
47、t. 6.3 Frequency weighting Frequency weighting and band limiting characteristics shall be in accordance with 7.3 of EN 1032:2003. 6.4 Integration time For each run, the r.m.s. acceleration shall be a linearly integrated average over one complete test run (see 9.2). 6.5 Speed The speed on the test tr
48、ack shall be measured using instruments measuring the average speed with an accuracy of 5 %. 7 Measurement location Where the exposed persons are sitting, the transducer mounted in a semi rigid disc shall be placed on the seat pan such that the transducer is located midway between the ischial tuberosities of the seated p
