Generating strain signals under consideration of road surface profiles

• The paper aims to generate fatigue strain signals based on the road surface profiles.
• Models for generating simulated signals were developed.
• The simulated data were validated extracting the damaging segments and comparing to the actual data.

The current study aimed to develop the mechanism for generating strain signal utilising computer-based simulation. The strain data, caused by the acceleration, were undertaken from a fatigue data acquisition involving car movements. Using a mathematical model, the measured strain signals yielded to acceleration data used to describe the bumpiness of road surfaces. The acceleration signals were considered as an external disturbance on generating strain signals. Based on this comparison, both the actual and simulated strain data have similar pattern. The results are expected to provide new knowledge to generate a strain signal via a simulation.
