Strength Checking of Caterpillar Tractor Guide Wheel Crankshaft under Working Condition
2014
Guide wheel crankshaft used in caterpillar tractor is analyzed under working condition. The crankshaft is made of 45Cr steel. Since the work conditions of the crankshaft are complicated, three dimensional finite element model of the crankshaft is built for strength checking of the crankshaft. Appropriate boundary condition is applied. The results show that the maximal stress of the crankshaft is 728MPa, which is less than the yield limit of 45Cr steel (835MPa). Therefore, the crankshaft can not be broken during the work of caterpillar tractor.
