Inputs

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

Outputs

Initial Conditions: the initial accelerations are from a small vehicle drop to initiate the solution
Accelerations: vehicle CG response to the obstruction
Axis Directions: x=vehicle side to side; y=vehicle travel direction; z=vehicle vertical direction
Time histories: compare obstruction and vehicle conditions
Visualization: response animation

Assumptions

Simplified 3D dynamics
Linearized elements
Use for sensitivity and early-stage decision support

Examples
