Excavator Design with Simscape
Design an excavator. Define pin locations, calculate BOF and TOF, produce load charts, and simulate dig cycles.
Updated 5 May 2023
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.
