Vibrational characteristics of automotive transmission
International Journal of Automotive Technology, 2009A mathematical model of an automotive transmission is developed, that considers the flexibility of the shafts, bearings, and gear teeth, and gyroscopic effects of geared rotors. The transverse, torsional, and axial motions are strongly coupled due to helical gearing. The excitation forces acting on the automotive transmission are classified into first,

Vibration analysis — Transmission line conductors
Electrical Engineering, 1934A method of measuring the stress distribution in transmission line conductors caused by vibrations under actual service conditions, and the effect thereon of various attachments, is outlined in this paper. Measurements have been made of the attenuation of traveling waves in conductors, reflection factors of supports, ratio of the bending at a clamp to ...

Transmission of vibration from a vibrating plate to the head of standing people
Sports Biomechanics, 2018Little is known about the transmission of vibration to the head when using whole-body vibration (WBV) training machines. This paper investigates the effect of frequency and posture on the transmission of vibration from a vibrating plate to the head of standing people.

Damping of the torsional vibrations of a transmission
Russian Engineering Research, 2014A method is proposed for damping the torsional vibrations of an automobile transmission. In this method, the rigidity of the damper is reduced to a value at which vibration is impossible.

The Vibration of Transmission-Line Conductors
Transactions of the American Institute of Electrical Engineers, 1928This paper is a continuation of a former one by the writer in May, 1926. Records are given of vibration in actual transmission lines under widely varying conditions and with various conductor materials. These observations indicate the limiting values of wavelength frequency and amplitude of such vibrations encountered in service. Laboratory experiments

Automobile and Transmission Vibration and Noise
2020The automotive vibration and noise is an important factor that affects the ride comfort. The automotive vibration and noise is complex and difficult to analyze, but can be represented by the basic mass spring model in most of the phenomena. It is very important to understand the automotive vibration and noise by means of mass spring model.

MECHANICAL VIBRATIONS IN TRANSMISSION LINES
Canadian Journal of Research, 1932Various types of vibration are discussed with special emphasis on the large and uncommon type of vibration known as "galloping". The effect of an ice coating on the line was investigated and could not be proved to enhance vibrations artificially introduced into the line.

Transmission of vibration in beam systems
International Journal for Numerical Methods in Engineering, 1969AbstractThree methods for finding natural frequencies and modes of complex structures composed of beam elements are described and compared. The analysis is extended to include hysteretic damping for the determination of response and transmissibility without a modal analysis.

Fingers vibration transmission performance of vibration reducing gloves
International Journal of Industrial Ergonomics, 2017Abstract Vibration attenuation performance of vibration reducing (VR) gloves is, invariably, measured at the palm using the method described in ISO 10819 (2013). The standardized method, however, does not address the glove performance in terms of fingers vibration, which is substantially different from that of the palm. An investigation was conducted
