Road-Friendly Suspension Virtual Test Bench
A simulation tool that lets suspension and truck manufacturers virtually test how their designs transmit dynamic tyre forces into pavement and bridge damage, replacing expensive physical road-damage testing with fast design iterations.
Concept
A model-based development tool for heavy-vehicle suspension engineers. The user defines a suspension design (spring rates, damper tuning, axle spacing, tire selection) and vehicle configuration; the tool simulates the vehicle over deterministic and random road profiles, computes the dynamic tyre forces transmitted to the pavement, and evaluates the resulting pavement and bridge damage using the mechanistic vehicle-guideway interaction models from the Handbook. The output is a road-damage report per design variant — dynamic force histograms, damage per kilometre, and the trade-off against ride quality — so engineers can iterate on suspension tuning to minimize road damage before building physical prototypes or running instrumented road-damage test vehicles. The single wedge: bring road-damage assessment into the simulation-first design loop.
Why now
The Handbook [0] provides, in one place, the full modeling chain needed for such a bench — vehicle dynamics, dynamic tyre forces, pavement and bridge response, damage mechanisms of paving materials, vehicle-guideway interaction, and suspension design to minimize road damage, including practical implementation issues. The underlying simulation components are mature: multibody vehicle dynamics, tire force models, and deterministic/random road profile modeling are textbook material [1], and controlled experiments established that instantaneous tyre force — with cornering/lateral forces the chief culprit — is the dominant wear/damage factor [5], giving the optimizer a measurable target. Because the Handbook also covers assessing road-damaging potential for regulatory purposes [0], suspension suppliers increasingly need design-loop evidence of road-friendliness rather than ad hoc physical tests.

AI assessment
A highly focused B2B simulation tool that converts established vehicle-road interaction physics into a design-loop utility for heavy-vehicle OEMs.
- Evidence strength 5/5
- The idea is directly grounded in a comprehensive handbook and supporting dynamics textbooks that provide the full mechanistic chain from suspension tuning to pavement damage.
- Market pull 4/5
- Major truck OEMs and suspension suppliers have a clear financial and regulatory incentive to reduce road-damage liability and physical prototyping costs.
- Novelty & moat 3/5
- While it shares a 'scoring' mechanism with the Road-Damage Potential Scorecard, it shifts the value proposition from fleet auditing to an upstream engineering design tool.
- Feasibility 4/5
- The physics are well-documented and the simulation components (multibody dynamics, tire models) are mature, making an MVP achievable with existing engineering software libraries.
- Wedge clarity 5/5
- The wedge is sharp and specific: replacing physical road-damage testing with a virtual test bench during the suspension tuning phase.
- Simplicity / focus 5/5
- The product is a single, focused simulation tool with one clear output (road-damage report) rather than a broad platform.

Who benefits
- Hendricksoncompany
A leading heavy-truck suspension and axle manufacturer; a virtual road-damage test bench would let it design and market demonstrably road-friendly suspensions while cutting physical prototyping cost.
- SAF-Hollandcompany
Major global axle and suspension supplier, especially exposed to European road-friendly vehicle policy; simulation evidence of low road-damaging potential would differentiate its products.
- Volvo Truckscompany
OEM with established vehicle dynamics simulation groups; adding a pavement/bridge damage dimension extends its virtual product development to an increasingly regulated outcome.
- Daimler Truckcompany
Heavy-truck OEM that could use the bench to certify the road-friendliness of factory suspension options and support regulatory submissions.
- Scaniacompany
Truck manufacturer with long-running research on road-friendly vehicles and heavy-vehicle effects on infrastructure; the tool operationalizes that research inside the design loop.
