Abstract | Nowadays, Thai farmers have started to use agricultural machinery for harvest as a substitute for human labor, which has greatly reduced. However, the use of these machines is quite limited and expensive. For these reasons, many groups of farmers could not afford them. So, our research team has designed and built a prototype combine harvester prototype (model ENG-MJU-003), which is the small combine harvester. It has a 30 hp engine and is driven by the four wheel drive rubber tires hydrostatic transmission driven. The research team found a problem with the strength of the front axle housing, where it was deflected after the test, as the front axle housing acts as a support housing for the combine harvester. Therefore, this research aimed to determine the strength of the front axle housing of the ENG-MJU-003 harvester by using the finite element method by comparing the front axle housing supporting the weight before and after improvement. The results of the strength analysis showed that the maximum stress of the beams before and after the improvement was 200.4 MPa and 65.4 MPa, the deflection was 0.33 mm and 0.13 mm, the safety factor is 1.2 and 3.8 respectively The results of the strength analysis by finite element method allowed the research team to develop a more appropriate directional support beam. After such improvements, the strength of the front axle housing is higher and is more practical without deflection. |
