Review Paper on Stress Analysis of Helical Spring Used in Tractor Seat Application

Over the year a lot of work has been done and is still continuing with great effort to reduce the cost and improving the performance of compression spring and also study the analysis of failure in spring. The aim of this project is to study existing design of helical spring and manufacturing the spring and carry out the vibration analysis of helical spring for Tractor seat .To reduced vibration at the time of dynamic loading condition, applied on helical spring.. At different load condition and vibration we have check the failure analysis of spring. In general we have studied vibration analysis of spring and also study the effect of varying the number of turns of the spring. In tractor seat vibration take place so we have to reduce this vibration by using suitable design and material. . The suspension of spring has to be modified in order to reduce the vibration and journey should be comfortable i.e. jerk free journey. Due to damping the helical spring gets break up and which causes the serious accident. so effective design of helical spring needed for tractor seat to get comfort and to withstand vibration. Our aim is to find the natural frequency of helical spring by using Finite element method (Modal Analysis) for tractor seat which ultimately gives strength characteristics , safety ,comfort and durability of spring and also to reduce the weight of spring for purpose of seat. General Terms- Helical spring, suspension systems.
