Hydraulic Rock Breaker Design
ANSYS • SOLIDWORKS • CES • CAM
Overview
Redesigned and optimized the piston and chisel of a medium-class hydraulic rock breaker based on the Vulcan V18GS platform. The project focused on structural performance, material optimization, and manufacturability.

Scope of Work
• Full assembly modeling
• Detailed redesign of piston and chisel geometries
• Material selection based on strength-to-weight criteria
• Finite element stress evaluation under impact load
• Topology comparison for performance improvement
• Manufacturing process planning (CAM toolpaths)
Outcome
