This work presents a study on the effects of suspension system on a Low Mass Vehicle (LMV) by changing its parameters to achieve an appropriate ¿ride performance¿. Both traditional and bond graph modeling techniques have been used to model and analyze the vehicle system, and a comparison between the two techniques has also been presented to decide which technique is suitable for the modeling and analysis of the vehicles' dynamics. Simulations have been performed in MATLAB and the 20-sim softwares for evaluating the ride performance, and based on these simulation results a classification for the vehicles has been proposed to see whether they are LMV or not. Furthermore, a framework for designing the LMV has also been proposed.

This book introduces and develops the mathematical models used to describe crane dynamics, and explores established and emerging control methods employed for industrial cranes.It opens with a general introduction to the design and structure of various crane types including gantry cranes, rotary cranes, and mobile cranes currently being used for material handling processes. Mathematical models describing their dynamics for control purposes are developed via two different modeling approaches: lumped-mass and distributed parameter models. Control strategies applicable to real industrial problems are then discussed, including open-loop control, feedback control, boundary control, and hybrid control strategies. Finally, based on the methods covered in the book, future research directions are proposed for the advancement of crane technologies.This book can be used by graduate students, engineers, and researchers in the material handling industry including those working in warehouses, manufacturing, construction sites, ship building, seaports, container terminals, nuclear power plants, and in offshore engineering.
