Originated from a project for the development of a Front-End Loader (FEL) truck Weigh-In-Motion (WIM) system, the research presented in this thesis concerns the static and dynamic analysis of the weighing process. The static analysis was performed on the truck arms for different loading conditions to obtain the stress distribution of the arm and detailed stress information on spots of interest. The dynamic analyses, specifically, free vibration analysis and transient analysis, were carried out on the overall truck system to provide oscillatory characteristics, including natural frequencies, mode shapes and time-varying stress curves. While the finite element method (FEM) was employed for both the static and dynamic analysis, an analytical method was also put forward on the free vibration analysis as a means of exploring alternative theoretical approaches. The analysis results were thoroughly discussed to provide observations and recommendations for the design. This research is essential to the WIM system development.
