About this app

With the PSD Profile Calculator, you can easily calculate the required forces and stroke lengths for vibration tests.
The app supports two modes:
• Simple: Direct entry of aₛₘₛ per frequency
• PSD: Definition of Power Spectral Density (g²/Hz) points

Functions:
• Calculation of maximum forces, total forces, and global load
• Stroke (peak-to-peak) analysis with limit check
• Diagrams with linear and logarithmic representation
• Support for multiple languages ​​(German, English, Czech)
• Dark mode and customizable display

Ideal for engineers, test technicians, and students in the field of vibration testing and mechanics.

Note: The results are intended for technical calculations and documentation, not as a replacement for test bench software.
