Hammer Rod Optimization of Large Tonnage Air Hammer

Article Preview

Abstract:

The hammer rod of large tonnage air hammer is easily damaged during operating process. Positions on the hammer rod, which may be broken, are not determined by linear fracture mechanics. Meanwhile, it does not provide possible measures for improvement. According to the actual weight of the hammer rod, about 0-10% larger than its nominal weight, an improved design method is proposed in the paper, which does not affect the performance of the air hammer. This method effectively solves the problem of breaking hammer rods and improves their service life.
