Tools
Main software
VTT has licences for several analyzing softwares for FE-modelling and simulation. For data aquisition and signal prosessing we have equipment for different kinds of purposes. We also use open source platforms, such as python (programming language) and Code_Aster (FE-modelling). We have experience on extending capabilities of commecial simulation tools by creating user scripts. We have also created specific in-house simulation tools, e.g. MODYSOL.

Facilities
High Performance Computing (HPC)
- Efficient computational research requires powerful computational resources.
- Own computing resources (such as several cluster systems, computing servers and high-end workstations) provides flexibility and speed in resource utilisation and data security
- “the Doctor”
- VTT’s largest computing cluster
- provides sufficient computing power even for demanding cases
- contains almost 100 computing nodes and over 2000 CPU cores
Resonance table 
- Can be used for vibration control research
- Table is supported with steel springs that allow 3D vibration
- Modal mass of the table varies from 250 to 1000 kg
- Resonance mode of the table is comparable to mode of an industrial machine or structure (e.g. diesel or electrical engine)
Shock test table
- Subjecting test specimens to high shock acceleration
- Quick and affordable validation of Your product shock tolerance
- Dimensions of the table: 1.0 m x 1.2 m
- Typical acceleration is 60 g and velocity 2.5 m/s when payload is 0-50 kg
- Typical acceleration is 50 g and velocity 2.4 m/s when payload is 250 kg
- Typical acceleration is 35 g and velocity 2.2 m/s when payload is 500 kg
Damper dynamometer 
- Measuring stiffness and hysteresis behaviour of dampers and structural members
- Dynamic force range, 0 - 8.9 kN , stroke depth 0 - 203 mm , frequency static - 100Hz
Drop tester
- Examing the damages of small specimens when dropped
- Dimensions: height 3100 mm, width 800 mm and depth 700 mm
We are equipped for comprehensive and demanding vibration testing:
- Measurement data acquisation systems for various needs
