Multi-Body Dynamics Simulation Service in India
Simulation-driven mechanism validation for automotive systems, robotics, industrial machinery, and aerospace applications. Extract joint forces, detect interference, size actuators — all before the first prototype is machined.
The Interference Problem That Shows Up After the Prototype Is Machined
Static CAD checks miss dynamic behaviour. Problems discovered in hardware cost 10× more than simulation-caught issues.
✦ Multi-Body Dynamics Simulation Prevents This

Real Project Reference
Automotive Suspension Linkage Validation
Potential Interference Risk
OEM flagged potential interference between anti-roll bar link and strut body at 90% jounce travel. Static CAD check was inconclusive.
MBD Model in MSC Adams
Full suspension assembly imported, joints defined, bump stop non-linearity applied, bump load cases mapped to measured road profile data.
2 mm Interference Detected
Dynamic simulation revealed a 2 mm interference at 95% jounce travel under combined lateral and vertical loading. Contact force spikes confirmed structural risk.
Issue Resolved Before Prototype
Anti-roll bar link geometry modified with 3 mm clearance target. Re-simulation confirmed zero interference across all load cases. Released for prototype.
