This example models an excavator with hydraulic actuation of the swing motor and cylinders for the boom, stick and bucket. A MATLAB App enables you to explore the mechanical and hydraulic design space to calculate digging and lifting forces according to international standards.
  • Pin locations can be adjusted in Excel or in the app.
  • Digging forces (BOF/TOF) are calculated according to ISO 6015:2016.
  • Pin loads are calculated for BOF, TOF, and lift capacity tests.
  • Load charts are determined at a range of arm positions.
  • Relief pressure thresholds can be analyzed for each function and the pumps.
  • Hydraulic regeneration valves are modeled to evaluate efficiency.
  • Dig cycle time and efficiency are determined in dynamic simulation.
  • Realistic soil loads are applied to the bucket using Discrete Element Modeling (DEM) software.
