Design and Development of Elliptical Leaf Spring for Vibration Isolation of Engine Mount

Mechanical Engineering

Agriculture machinery driven by engines generate vibrations that are substantial audible as noise and painful to hand. This reduces efficiency of farmers or farm labor. Hence it is necessary that the vibrations generated by engine be reduced or isolated from the handle or body of application, so that the operator was feel lesser fatigue. Hand-arm vibration (HAV) is transmitted from a work processes into workers’ hands. It is caused by operating hand-held tools, hand-guided equipment or by holding materials processed by machines. Multiple studies has shown that regular and frequent exposure to HAV can lead to permanent adverse effects, which are mostly occur when contact with a vibrating tool or work process is a regular and significant part of a person job. Hand-arm vibration cause a range of conditions collectively known as hand-arm vibration syndrome (HAVS) as well as specific diseases such as white finger, carpel tunnel syndrome. It has adverse circulatory and neural effects in the hand. The symptoms include numbness, pain, and blanching (turning pale and ashen).
