Partner Spotlight: VMAP by TechPassion

VMAP by TechPassion – HW Partner Alliance Spotlight

Noise Vibration and Harshness

VMAP is a comprehensive software tool for vibration testing on real-world engineering systems that seamlessly connects virtual simulation and physical testing.


  • Addresses the needs of both beginners and expert users.
  • Calculates damping, resonant frequencies, MAC (Modal Assurance criteria) and other parameters with just a few mouse clicks.
  • Programming interface to develop curve fitting algorithms, update finite element simulation models with the damping estimates obtained from VMAP and analyze the updated simulation models.
  • Identify the failure modes in prototypes quickly and reduce product development cycles.
  • VMAP is available as a plug-in within HyperMesh.

“In 1949, the concept of FRF was developed. Yet, the engineers never had a simple tool to conquer vibrations in engineering systems. VMAP sets a new standard as the most advanced and user-friendly experimental modal analysis and FEA-Test correlation software package. In a nutshell, I wish VMAP was around when I was doing my research at MIT ten years ago.”
