Simulation of pneumatic & hydraulic drills and breakers
Pneumatic and hydraulic (rock) drills and breakers typically are equipped with a piston impacting the drill or steel that does the actual work. Design challenges of this type of equipment includes the high stress waves traveling through the drill/breaker body including piston and associated parts.
Pneumatic and hydraulic (rock) drills and breakers typically are equipped with a piston impacting the drill or steel that does the actual work. Design challenges of this type of equipment includes the high stress waves traveling through the drill/breaker body including piston and associated parts. The high stress waves can cause fatigue and fracture/failure, especially as notches and other stress/strain-concentrations.
LS-DYNA is an ideal tool for analysis of these types of machinery, well proven and very fast.
