(some col.) ; 30 cm. + 1 computer disc Project paper (Bachelor of Mechanical Engineering with Automotive) -- Universiti Malaysia Pahang - 2008 Prediction of fatigue life on piston for four stroke engine using variable amplitude loading is presented. The piston is the crucial part of the internal combustion engine. The objectives of this project are to predict fatigue life of piston for four stroke engine using strain-life method, to identify the critical locations, to investigate the effect of mean stress and to optimize the component material. The structural and finite element modeling has been performed using a computer aided design and finite element analysis software package. The finite element model of component then analyzed using the Strain method approach. Finally, the stress-strain state of component obtained previously will be use as input for the fatigue life. The effected mean stress and materials optimize was also too investigated. The failure of piston can result in devastating damage to the engine including all the components from a tiny screw till a huge belting system. Life of piston needs to be improved to prevent from any unpleasant problems. The results of the analysis showed that there are no serious failure occurs at the part of the piston. However it is observed that the minimum predicted life at the critical location is 102.38e-7 under variable amplitude loading for strain-life approach. The optimization results showed 7075 T6 aluminum alloy that is the most superior material among the others. -Author- Fatigue testing machines Finite element method Pistons 0 0 0 1 20000 20000 2019-09-04 0 TA418.38 .M39 2008 rs Bc. 0000038118 2019-09-04 00:00:00 1 2019-09-04 PSM 0 0 0 1 20000 20000 2019-09-04 0 CD 3412 | TA418.38 .M39 2008 rs Bc. 0000038119 2019-09-04 00:00:00 1 2019-09-04 PSM VIRTUA40 1209 1215 VTLSSORT0080*0200*0400*0900*1000*2450*2460*2600*3000*5020*5200*6500*6501*6502*9992
