Abstract:

Purposes of the study were to measure mechanical vibrations transmitted to train operators, to calculate daily whole-body vibration exposure levels, to compare measured levels with maximum acceptable exposure levels according to the international standard on whole-body vibration, to identify factors that influence vibration levels, and to quantify the effects of these factors on the measured levels. As a result of this study, it was determined that six out of twenty subway lines had vibration levels higher than the daily exposure limits recommended by the international standard, and that train

Abstract:

Vibrations that arouse human health concerns are classified into two main categories: (1) hand-arm vibrations (HAV) and (2) whole-body vibrations (WBV). Hand-transmitted vibration from a power or impact tool affects the upper extremities of the body. WBV affects the entire body and is transmitted from a vibrating seat, bed or floor to a person who is in a sitting, Iying or standing position. The EU Directive April 5, 2002 provides exposure limit and action values for both HAV and WBV. These values have taken into consideration recent advances in knowledge and the political judgment of the Memb

Vibration is a complex mechanical oscillation of solids that can be transmitted directly to the body. By exposing the body to vibration, tissues begin to move from their natural position. In the work setting, there are basically three types of vibration that are medical significant: whole body vibration, segmental vibration and human resonance. When the body comes directly in contact with mechanical vibration, a direct adverse physiological and physical effect occurs on that body. This type of effects interferes with work efficiency and productivity of labor and, in some situations, can put th

The test proved that the allowed vibration level was exceeded, especially within the low frequency region from 6.3 Hz up to 125 Hz.

Abstract:

Vibrating mills are one of the most advanced types of grinders, which have high productivity and combine a sufficiently high intensity of technological action with a relatively simple construction. The main parameter of vibrating mills is the amount of maximum power transmitted to the load through the chamber by the vibrating exciter at a given value of the forcing power developed by it. It was found that the maximum power is transmitted to the load when the chamber moves along a circular trajectory. Thus, it was determined that an equivalent forcing power should be applied near the center of

Vibration transmissibility from a car body to pedal-pad could result to drivers discomfort and fatigue, which may lead to health problems. Vibration transmissibility occurs when the vehicle engine is turned on and vibration is transmitted from the car body to pedal-pad in this research Pedal-pad effective Amplitude Transmissibility (PEAT) value was used to predict suitable size of the pedal-pad that could provide comfortable operation of the pedal. In this study, the variables are the three different sizes of pedal-pads and data was recorded while the car was moving on the road at constant spe

Background. Since over century it has been known that hand to arm transmitted vibrations (HAV) can affect health and quality of life. Exposure over certain level and intensity over time are risk causes of Hand Arm Vibration Syndrome (HAVS). Symptoms varies from the damaged structures which most commonly are secondary Raynaud Phenomenon known as Vibration Induced White Finger (VWF), carpal tunnel syndrome, tingling, loss of manual dexterity, osteoarthritis or even Dupuytren’s contracture.

<strong>Abstract</strong> Tractor users in forestry, as in other technological applications and professions, are faced with serious spinal disorders due to some negative features of vibration. In this study, vibration transmitted to the operator from tractors used in forestry in Turkey and the effects of this vibration on human health were evaluated. After giving general information about vibration and its effects, ergonomic measures to be taken for tractor users to work in a healthier, safer and more efficient way are presented.

Abstract:

Tunnel blast-induced vibration probably causes damage to the rock mass surrounding the tunnel surface and also to the rock mass of the slope at the tunnel entrance. It is important to simultaneously monitor the vibration on the tunnel surface and on the tunnel entrance slope face, especially when the blasting work face is close to tunnel entrance. During blasting excavation of the traffic tunnel at Baihetan hydropower station, vibration monitors were installed both on the tunnel surface and on the tunnel entrance slope face. Based on the monitoring data, a comparative study is conducted on the

Abstract:

Previous studies have shown that exposure to whole-body vibration can interfere with comfort, activities, and health. In analogy to materials handling it is assumed that the elevated spinal forces are a crucial component in the pathogenesis of the health impairment. To estimate the forces a biomechanical model was developed. In the model the human trunk, neck and head, the legs, and the arms are represented by 27 rigid bodies. An additional body simulates the vibrating vehicle or machinery. The bodies are connected by visco-elastic joint elements. In total 106 force elements imitate the trunk,

There is some epidemiological support for the EAV A(8) of 2.5 ms–2 r.m.s. and the ELV A(8) of 5 ms–2 r.m.s. for HTV, at least for the vascular component (secondary Raynaud's phenomenon)

Whole-body Vibration (WBV) is a well- known occupational health hazard in mining industry. Dumper operators are subjected to WBV generated from road-tyre interaction and transmitted through the base of the seat.

Abstract:

Road surface roughness excites low- and high-frequency vibration modes of a heavy articulated vehicle body. These vibrations result in motions in all directions that detract from the driver’s perceived ride and comfort and increase pavement damage due to dynamic wheel loads (DWLs). A subjective assessment survey was conducted to identify surface roughness characteristics that mainly influence the perceptions of heavy-vehicle drivers of pavement rideability and their comfort. The latter was achieved by correlating drivers’ ratings to roughness contents in different roughness wavebands. The resu
