Design of Suspension System for HADMBA Thresher Machine with Finite Element Analysis Approach

In agricultural field, the Hadmba thresher machine is use to separate the grains from the stalk and the pod of the plants; A national institute for safety (NIFS) has investigated the breakage of hub bolts due to absence of suspension system in the Hadmba thresher machine. In rural India, the condition of road is very bad and in order to travel the Hadmba in such road conditions, the suspension system must be there in the machine to increase the life of the parts. This work involves design and analysis of a hub bolts and a leaf spring in existing and new designed Hadmba thresher machine under static and dynamic loading conditions. The modeling is done in Creo 1.0, and then analysis is performed in the ANSYS 11.0 by considering loading in static and dynamic conditions. The main concept use of leaf suspension system is to reduce the vibration energy of the vehicle body induced by the road roughness while keeping the vehicle stability within an acceptable limit. The different results were obtained and verified mathematically with Ansys. All analytically calculated values of deflection and stresses are closely matching with values obtained from ANSYS software.
