Lecture on Load Movement in Systems Using Physics Simulations

Key Concepts

• Physics in Simulations: Movement of loads in a system is governed by physics.
• Physics Simulation: Used to analyze forces on objects, including friction coefficients.

Process of Load Movement

1. Load Generation: Loads are generated and placed onto systems like conveyors.
2. Physics View:
   • Activation through visualization tab or F8 key.
   • Shows forces acting on loads, such as gravity and friction.
3. Forces and Friction:
   • Gravity pulls loads onto conveyors, shown as blue lines.
   • Friction, shown as yellow lines, moves loads forward on conveyors.
   • Coefficient of friction between surfaces affects movement (e.g., 0.4 between box and moving surface).
4. Load Acceleration and Impact:
   • Loads accelerate with conveyor motion and eventually impact another surface.
   • Different surfaces have varying friction coefficients affecting deceleration.

Alternative Simulation Modes

Discrete Event Simulation

• Purpose: Simplifies simulation by focusing on position and contact points.
• Behavior: Moves loads based on location (e.g., on a conveyor) rather than applied forces.
• Benefits:
  • Faster simulation runs.
  • Loads maintain position without complex interactions like tumbling.
  • Suitable for situations where detailed physics are unnecessary.

Linear Physics Engine

• Overview:
  • Simplified and faster than volumetric physics.
  • Manages behaviors such as merges automatically.
  • Places loads consistently on conveyors.
• Availability: Limited to certain license types.

Choosing a Simulation Mode

• Detailed Physics Needs: Use full physics simulation for precise interactions like merge behavior or load snagging.
• Simplified Simulations: Use discrete event or linear physics for less detailed needs.
• Customization: Different engines offer varying levels of customization and complexity, suitable for different application needs.
