Establishment of Analysis Method for Weight Reduction Design of Motorcycle Frame Parts

Article of Honda R&D Technical Review Vol.18 No.2


In the present development of motorcycle frame parts, basic skeleton layouts are designed by repeating some examinations in order to achieve weight reduction considering rigidity and strength targets. Various structural optimization technologies were studied to reduce the man-hours required for the repeated examination. Instead of expanding the design area of the topology optimization technology, an analysis was established by using a method of virtual rigidity enhancement. The analysis obtains ideas easily and rapidly for weight reduction in consideration of rigidity.
