Focusing on the stiffness formulation of a three prismatic-revolute-spherical parallel kinematic manipulator (3-PRS PKM), this book explores the inverse position analysis using vector approaches. It addresses the challenges of determining stiffness distributions due to complex geometries, employing ANSYS technology for computation at various configurations. The developed semi-analytical stiffness model allows for estimating system stiffness based on geometry parameters and load situations, solving stiffness in x, y, and z directions through a transformed stiffness matrix.

Focusing on advancements in power transmission systems for green and lightweight vehicles, this book highlights the significant investments made by governments and businesses in eco-friendly technology. It explores innovations aimed at reducing costs and enhancing the efficiency of low fuel consumption vehicles, ultimately aiming to decrease fuel consumption and exhaust emissions. The content emphasizes the importance of these developments in promoting environmentally sustainable transportation solutions.
