25、BS EN 1915-3:2004+A1:2009EN 1915-3:2004+A1:2009 (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
26、 whole body vibrations under stationary operating 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
27、the tyre specification, etc. can lead to different 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
28、 European Standard cannot be used for field measurements 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-
29、 cated in the scope of this document. When provisions 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 accord
30、ing to the provisions of this type C standard. BS EN 1915-3:2004+A1:2009EN 1915-3:2004+A1:2009 (E) 5 1 Scope !This European Standard deals with whole body vibration as a significant hazard.“ It also specifies the methods for determining the vibration emission transmitted to the whole body of drivers
31、 standing and/or seated on freely moveable GSE, 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
32、in conjunction with the other parts of EN 1915, and with the relevant part of EN 12312.“ 2 Normative references The following referenced documents are indispensable for the application of this document.

38、river is seated 4 Vibration reduction Vibration emission 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 betwee
39、n the machine and the surface of the ground. Measures 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
40、 the instruc- tion handbook shall, when appropriate, 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.
41、5 Quantities to be measured The quantities to be measured are as follows: a) The root mean square (r.m.s.) acceleration ) ( wz a 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 vib
42、ration components as defined in EN 1032:2003, Clause 6 in the horizontal directions, the summation a wshall 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 me
43、asured on the floor of the driving position with one standing 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) Th
44、e mean GSE speed when travelling on the test track. This 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+A1:2009EN 1915-3:2004+A1:2009 (E) 7 c) Pneumatic tyre pressures (see also 8.2.2); d) Ambient air t
45、emperature. NOTE 2 If a standard vehicle is used for 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 cha
46、nges in design or construction which affect the vibration 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,
47、 the transducer shall be mounted in a semi rigid disc 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
48、rigid plate upon which the driver can place both feet. 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 track 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
