Join the Component-Based TPA and Virtual Prototyping Master Class, a 3-day live training at Siemens DISW Engineering in Newark,CA. This event gathers the NVH community for enriching lectures and learning application insights from industry experts, OEMs, and suppliers. Experience live demonstrations, interactive sessions, multiple hands-on workshops, and an expert panel discussion, all designed to enhance your practical skills in transitioning from physical prototype troubleshooting to virtual prototype prediction.
This master class aims to strengthen your network and create an inspiring innovating environment. It is designed for NVH managers, experts, and engineers at OEMs and suppliers working towards reducing physical prototypes, orchestrating seamless interaction between independent development teams within or outside the organization and getting inspired by new methodologies for NVH engineering. CTPA and VPA technologies are key to combine test and CAE models, learn how to predict system behavior after integration, and skill-up your measurement as well as CAE capabilities in developing virtual assemblies for predictive analysis.
This course is for designers, engineers, and CAD/CAM managers who need to create parametric solid models that capture design intent.

PRIMARY COURSE TOPICS
Day 1
The essentials behind virtual prototyping for NVH: From physical prototype troubleshooting to virtual prototype prediction. The theory behind component-based TPA & in-situ TPA:
- Methods for obtaining reliable invariant structural loads
- Addressing airborne loads
- Coupling sources towards receiving structures, using
- Frequency-based sub structuring
- How to do instrumentation for in-situ TPA

- Invariant source characterization on tire, auxiliaries, and
- powertrain case studies
Day 2
Component modeling and virtual prototyping process: In this session, we explain how to take the technology discussed so far, toward an implementation across the full NVH development.
- Creating test or CAE-based component models for more easy and fail-safe coupling for virtual assemblies, using data from different stakeholders
- Example: NVH predictive analysis using Virtual Prototype methodology.
- Typical VPA implementation pitfalls and ways to overcome those.
- Examples: Company wide component models management process and ways to maximize VPA process use for NVH engineering.
FRF data collection techniques:
- Considerations on different measurement techniques for FRF data collection. From impact hammers to shakers.
