Details (inputs, outputs, assumptions) Read once

Inputs

  • Best use: make sure your browser supports WebGL/Three.js by going to https://get.webgl.org
  • Geometry / masses: chassis, cab/cargo and untethered cargo dimensions and weights
  • Wheels / suspension: axle locations and front and rear suspension K and C values
  • Tires: effective vertical stiffness
  • Road: road feature profile and vehicle speed
  • Helpful hint: the model and results can be saved to a JSON file for future use

Outputs

  • Accelerations: ride severity cargo response proxies
  • Time histories: compare cases and damping effectiveness
  • Visualization: response animation

Assumptions

  • Simplified vertical dynamics
  • Linearized elements
  • Use for sensitivity and early-stage decision making
