In this work, geometric and kinematic modeling of the gear-based crank mechanism engine (GBCM) was performed. To this aim, a mechanical approach based on projective computational methods and mechanism ...

China is the world’s largest producer and consumer of coal, with an increasing demand for coal resources. Improving coal mining efficiency and ensuring production safety have become key issues that ...

Italian researchers used finite-element analysis to simulate kinematics and internal stresses following TKA and applied a three-dimensional approach using the Meniscal Bearing Knee prosthesis to ...

Determining whether or not a mechanism will work before building physical prototypes can be time consuming and challenging, especially for new designs. At one time, only physical prototypes made it ...
