New frequency weighting of hand-arm vibration.
A new frequency weighting method to assess hand-arm vibration exposure is proposed in this paper. The influence of frequency components was first estimated using the method of multivariate analysis, then a simple form of the weighting curve was introduced. Compared with the frequency weighting in the current ISO 5349-1 (2001), the proposed weighting can better explain the relationship between r...
متن کاملMeasurement of ground-to-building frequency response functions for assessment of human exposure to vibration from railway vibration
The University of Salford has derived exposure-response relationships for vibration caused by railway construction and operation in residential environments. The exposure assessment methodology for almost 1000 case studies has its key factor in the measurement of synchronized ground-to-building frequency response functions (FRF). The latter is obtained by averaging the spectral content of simul...

در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...
15 صفحه اولMeasurement and Analysis of Low Frequency Vibration
Low frequency vibration occurs especially in ground transportation, either as a cause in adjacent environment or within the vehicle itself. The piezoelectric accelerometers commonly used for vibration measurement are not suitable, hence other sensors capable of measuring accelerations down to sub-hertz region have to be used. Based on some previous experience with MEMS acceleration sensors a th...
متن کاملSubjective Responses to Hand-arm Vibration: Implications for Frequency-weighting and Gender Differences
Exposure to vibration transmitted to the hands and arms may increase the risk of developing chronic disorders. Current ISO standards regarding exposure are based in part upon assumptions regarding the relationship between threshold measurements and subjective experiences of vibration at higher intensity levels. This study investigated this relationship by comparing absolute threshold levels at ...
