8、0-09 Foreword This standard has been prepared by Working Group NA 001-03-09 AA (NALS/VDI C 9) Messung von Schwingungsimmissionen of the Normenausschuss Akustik, Lrmminderung und Schwingungstechnik im DIN und VDI (Acoustics, Noise Control and Vibration Engineering Standards Committee in DIN and VDI).

9、 Vibration control regulations require measurements to be made in order to record and assess the effects of mechanical vibrations on buildings and on humans in buildings and to test the effectiveness of any protective measures taken. The uncertainty associated with the results of these measurements

10、depends on the accuracy and stability of the vibration measuring system (vibration meter) used, as well as on the chosen measurement method and other factors, such as the source of the vibration (see DIN 45669-2). DIN 45669 consists of the following parts, under the general title Measurement of vibr

EN standards with numbers starting with 6 are identical to IEC standards with the same number, which are available in English. Translators note. Index eff stands for root-mean-square (r.m.s.)

12、value. Amendments This standard differs from DIN 45669-1:1995-06 and DIN 45669-3:2006-06 as follows: a) the standards have been revised and combined; b) particular attention has been given to the special characteristics of digital vibration meters; c) the distinction between different accuracy class

13、es has been deleted; d) the standardized designation of the vibration meter has been deleted, so that information has to be provided on the relevant data sheet; e) the assessment velocity vBhas been introduced for assessing the effects of transient, or short-term, vibrations on buildings. Previous e

14、ditions DIN 45669-1: 1981-01, 1995-06 DIN 45669-3: 2006-06 3 DIN 45669-1:2010-09 1 Scope This standard specifies requirements for vibration measuring systems (vibration meters) and specifies verification procedures that are graded in terms of effort and accuracy. These vibration meters can be used i

15、n the field of vibration control to measure mechanical vibrations affecting buildings and/or humans in buildings. The requirements for frequency weighting and time averaging, which are fundamental to quantifying assessment parameters, follow from the specifications in DIN 4150-2 and DIN 4150-3. Thes

16、e requirements can be realized in digital or, if technically feasible, analogue vibration meters. This standard specifies the minimum extent of testing to be carried out by or on behalf of the manufacturer or user in order to verify that the requirements for the vibration meter have been met. The st

17、andard also specifies which information is to be included in the documentation of the relevant verification procedures. If this standard is used in conjunction with DIN 45688 and DIN EN ISO/IEC 17025 for the accreditation of testing laboratories and engineering consultancies in the field of vibratio

18、n immission control, it applies solely to the area relating to measuring and testing equipment. Specifications regarding the verification process and the mounting of the vibration transducers are set out in DIN 45669-2. The assessment of the measured data for immission control purposes does not form

19、 part of this standard (see DIN 4150-2 and DIN 4150-3). However, a method is specified in Annex E with which assessments based on the provisions of DIN 4150-3:1999-02, Table 1, can be automated. 2 Normative references The following referenced documents are indispensable for the application of this d

27、 apply. 3.1 measurand measured quantity vibrational displacement, vibrational velocity (particle velocity) or vibrational acceleration (particle acceleration) recorded at the transducer over a given period of time 3.2 transducer sensor seismic transducer for the chosen measurand whose output signal

28、is a non-mechanical signal (measurement signal) that is proportional to the measurand 3.3 unweighted (velocity) signal particle velocity signal v(t) band-limited signal proportional to the particle velocity NOTE 1 For more information on bandwidth limitation, see 5.1.4. NOTE 2 When measuring vibrati

29、on in buildings, vibration velocity (particle velocity) is the preferred measurand because an approximately linear or close-to-linear relationship has been demonstrated between particle velocity and the stresses to which building components are subjected when exposed to steady-state or transient vib

30、ration. The ability of humans to perceive vibration at any one instant in time is also directly proportional to vibration velocity over most of the operating frequency range specified here. In addition, by recording vibration velocity over time, information can be gained about how vibration displace

31、ment or vibration acceleration varies over the same period, even in the case of composite vibrations with different amplitudes. This would be more difficult if, for instance, acceleration was chosen as the measurand as the frequency-dependence of the vibration acceleration means that the higher-freq

32、uency amplitudes would dominate. 3.4 Signal inputs 3.4.1 digital input interface in the signal path on the input side of the vibration meter at which time series of the unweighted signal (particle velocity signal) v(t) can be fed in for the purposes of testing the meter or for subsequently analysing

37、NOTE While the weighting filter is, in principle, independent of the band-limiting filter, the effect of both filters is usually taken into account. 3.9 frequency-weighted signal signal that results from applying a weighting filter to the unweighted signal (particle velocity signal) NOTE A frequency

38、-weighted signal arises from applying a frequency weighting function (see Equation (4), Figure 4 or Annex E). Although this standard only covers the frequency weighting of vibration velocity (particle velocity) signals, it is also possible to weight signals that are proportional to vibration displac

In contrast, time averaging (here “fast time averaging”) causes additional ripple in the time history of the indicated quantity, which in turn results in values of KBFmaxand KBFTm at low frequencies that are higher than the long-term average (see Annex B for more informa

47、tion on the ripple effect). 5.2.3.4 Phase response functions The following design phase response functions are derived from the complex frequency response characteristics detailed in 5.2.3.2: fffffffff0,80,82arctan + 0,80,82arctan = )(oouuuSoll (8) ffffffffffHz 5,6arctan + 0,80,82arctan + 0,80,82arc

49、 in the range 2,5 Hz f fo. A suitable procedure for testing conformity with this requirement is given in Annex C (“tangent method”). NOTE Users of this standard should note that the phase response can have a significant effect on the peak particle velocity vmaxof anharmonic vibration and can also affect the maximum weighted vibration severity KBFmax, though to a 21 DIN 45669-1:2010-09 lesser degree. This standard specifies a phase response that is simple to realize in practice (even in
