“…The steel sheet hood of Renault 361 tractor showed similar vibration behaviour. Furthermore, Freydooni et al (2012) came to similar results as previous authors -the minimum value of tractor vibration occurred at engine rotational speed of 1300-1400 rpm; after exceeding these values, the vibration increased proportionally to engine speed. As it can be seen, increasing the rotational speed from 1400 to 2200 rpm increased the vibration in both modes -with and without balancer.…”

The mechanical vibration causes health issues to drivers, such as backache, spinal cord injury, etc. In this regard, a tractor engine plays important role. Tractors without chassis are equipped with a balancer unit reducing the secondary engine vibrating force and decreasing the engine and tractor vibration. The paper presented investigates the effects of balancer on secondary vibration. In this research, the root mean square (RMS) of vibration was computed for specific periods of engine work. Effects of rotational speed and engine load on engine vibration in two modes with and without balancer were investigated. The results showed that, at full engine load, increasing the engine speed resulted in increasing the vibration in both observed modes. Balancer utilization reduced the vibration by 22.3% on average. At fixed rotational speed, increasing load caused an increase in vibration in both observed modes. At 1400 rpm rotational speed and 125 Nm torque, balancer utilization managed to reduce the RMS of secondary vibration by 38.9%. Furthermore, at 250 Nm, RMS vibrations were reduced by 21.3% in comparison to no balancer mode. At full load, variable rotational speed, the balancer significantly reduced vibration by 29% on average. The balancer proved to be more efficient at lower torques.

As India is the second largest manufacturer of two wheeler Motorcycles, so most of the Indian population prefer two wheelers for their daily travelling. There is also some reasons like economic, travelling distance and traffic on city roads behind preference given to two wheelers. During travelling on two wheelers many parts of body are directly in contact with vehicle but Hands are main interface between rider and two wheeler. While travelling, handlebar transfers vehicles vibration to human body. These vibrations are due to engines inertia and combustion force, road induced vibration & improper structural designs and they are quiet varying with respect to speed, fuel supply. The prolonged exposure to these vibration may affect different parts of human body mostly hands, spine, lower back. This exposure to part of body of operator is called as "Segmental vibration" which will result in "hand-arm vibration syndrome" (HAVS). These vibrations also results in mental retardness and high blood pressure which are very severe. This paper is the review the work in the area of HAVS and reveals the fact that, up to certain limit vibration are not hazardous but after exceeding that limit they are very hazardous.

In the design of automotive components the use of numerical simulations has contributed to reducing the design time, decreasing the prototypes costs and increasing reliability of the final product. However is necessary a investigation on human body vertical vibrations transmitted by different types of vehicle for the purpose of recognition the danger and guiding to eliminate of risks of discomfort theirs. This study, the object is to compare the discomfort levels of occupants when different vehicles (car, bike and bus) move over a speed bump. The results show that wheelbase, wheel size and vehicle weight can lead to different vehicular discomfort results. Results of the study demonstrated that heavy vehicles occupants (bus or truck) are subject to discomfort greater than occupants of light vehicles (cars and motorcycles) ones.
