Modeling and analysis of the interaction between the crutch and the ground in h...

Biomechanics of human motion is a multidisciplinary field that involves the study of the mechanical aspects of the human body and the impact that forces have on the movement of the anatomical segments. The use of computational tools to understand the dynamic behavior of the human movement has been rising due to the wide range of applications related to improving performance or treating injury. The knowledge on ...

Race Party: a project-based learning approach to teach dynamics and design of m...

First Online: 24 May 2025; This work presents the Race Party, which is a project-based learning approach utilized at the University of Minho to teach dynamics and design of mechanical systems. The Race Party, launched in 2015, has been incorporated into the “Integrated Project in Mechanical Engineering” course, which is part of the second-year curriculum for the bachelor’s degree in mechanical engineering. The ...

Kinematic and inverse dynamic analysis using mixed and fully Cartesian coordina...

The propagation of errors along a kinematic chain, caused by using drivers computed from noisy data, can affect the accuracy of the kinematic and dynamic outcomes. Minimizing the effect of such errors is crucial, particularly when traditional smoothing techniques prove to be ineffective. This work expands the multibody formulation with Fully Cartesian Coordinates and a Generic Rigid Body (FCC-GRB) to the invers...

Representações axonométricas

[Excerto] É sabido que em desenho técnico existem, fundamentalmente, dois tipos de representações, a saber: a representação ortográfica e a representação perspética. Na representação ortográfica usa-se um conjunto apropriado de vistas, as quais são obtidas segundo direções perpendiculares às faces principais do objeto que se pretende representar.

Fully cartesian coordinates with a generic rigid body: an application to biomec...

The present work explores the application of the spatial FCC-GRB formulation to the analysis and simulation of biomechanical systems, highlighting its advantages and limitations compared to other global formulations. It outlines the general principles for modeling biomechanical systems, including musculotendon units (MTU) and contact models. Additionally, this study addresses the use of mixed coordinates for co...

Teaching dynamics of mechanical systems using a practical project: the dragster...

The objective of this study is to present a simple, practical and comprehensive project to teach dynamics of mechanical systems in undergraduate level engineering courses. For that purpose, the dragster car challenge is utilized as a practical application example, for which a pedagogical activity where the students, organized in groups of five and supervised by tutor, design, model and analyze the dynamic perfo...

Kinematic and dynamic analysis of spatial multibody systems based on a formulat...

This work introduces the Fully Cartesian Coordinates Formulation with a Generic Rigid Body (FCC-GRB), a novel global multibody formulation for three-dimensional mechanical system analysis. The formulation's intrinsic characteristics are thoroughly detailed and compared with other widely-used global formulations, enabling its application in both kinematic and dynamic analysis of complex mechanical systems and as...
