| Abstract: | The effects of hollow structure on static bending and fatigue strength of a model 6100 nodular cast iron crankshaft were investigated by means of strain gauges and a DC-1 tester. Test result showed that with proper hollow structure, the static bending strength of crankshaft could be increased by 6% - 15%, fatigue limits by 4% - 8%, while the weight could be reduced by 4 - 5kg. |
