Studying the Possibility and Requirements of Using an Electronic System Dedicated to Stationary Applications on a Moving Vehicle
摘要
To avoid the prohibitive costs associated with purchasing specialized electronic systems designed for mobile applications, many organizations with limited financial resources are seeking to adapt their existing stationary systems for use in vehicles. This transition presents unique challenges, as it necessitates a thorough evaluation of the systems' capabilities to ensure they can perform their intended functions reliably under the dynamic conditions experienced in mobile environments. This paper proposes a methodology to assess the feasibility and requirements for adapting an electro-optical platform, originally designed for stationary applications (e.g., mounted on a building), for use on a moving vehicle, considering that operational stability is essential for optical performance of the platform.
MethodsThe proposed methodology is based on determining the natural frequencies of the printed circuit board (PCB), the most sensitive component of the platform, experimentally, using Sine sweep testing, and numerically, using finite element modeling, then, evaluating the frequency content of the loads affecting the board by field measurement of the loads acting on it, and finally, assessing the nature of the board response (static or dynamic) through the position of natural frequencies relative to the frequency content curve.
ResultsThe obtained results confirmed that the platform’s PCB responds dynamically, and the structure of the platform must be radically modified to make it suitable for mobile use on a vehicle.
ConclusionIt also emphasized that the approach adopted in the research is appropriate and can be used whenever the need arises, and in parallel, work must be done to develop this approach to find a systematic way to modify systems that respond dynamically without resorting to the method of trial and error.
