Abstract

In this thesis, the transfer function of a camera mount is obtained using ANSYS and MATLAB. In a heads-up display (HUD) application, achieving precise image registration requires careful consideration of the camera's position relative to the vehicle. Vibrations can alter the camera's position, with tilt being the most impactful due to its increased displacement effect as objects are further away.This research tackles vibration by predicting the position of the camera using transfer function. To determine the transfer function for complex structures, such as camera mounts, this study aims to first establish a transfer function for a simpler model, like a cantilever beam with a tip-mass. By contrasting the transient response from ANSYS with the theoretical response of the system, the ANSYS modeling is validated as part of the process. The system identification toolbox in MATLAB is then used to produce the transfer function based on the frequency response function (FRF) that was developed in ANSYS harmonic analysis. By comparing the simulated outputs to ANSYS transient responses with the same inputs, the transfer function is verified. The results show that the transfer function developed successfully predicts the position of the camera with an accuracy of 98%.
