This paper presents an approach using Frequency Response Function to inversely determine impact forces in structural component and machine members. A Frequency Response Function (FRF) is a transfer function expressed in the frequency domain obtained using either measured data or analytical functions. A frequency response function was generated for all input and output combinations for a cantilever beam using force data and acceleration data in the frequency domain. The force data was acquired using impact hammer and their responses were measured using accelerometer in LabVIEW software. Further the impact peak force of the hammer was compared with the force recreated using FRF at those locations and their results were plotted and compared. Further a prototype vehicle model was developed and an attempt was made to recreate the forces using generated FRF for single wheel, 2 wheels and 4 wheels using impact hammer and results were plotted and compared. This particular method of force identification was later applied for obtaining the maximum impact force using FRF when the vehicle model was dropped from a particular height.
