Thermal Parameter and State Estimation for Digital Twins of E-Powertrain Components
(IEEEAccess, 2021-07)
[Abstract] The performance of powertrain components in electric vehicles is tightly intertwined with their thermal behavior. In practical applications, their temperature must be monitored and kept below certain thresholds ...
Load assessment and analysis of impacts in multibody systems
(2016-09)
[Abstract] The evaluation of contact forces during an impact requires the use of continuous force based methods. An accurate prediction of the impact force demands the identification of the contact parameters on a case-by-case ...
Multibody-Based Input and State Observers Using Adaptive Extended Kalman Filter
(MDPI, 2021-08)
[Abstract] The aim of this work is to explore the suitability of adaptive methods for state estimators based on multibody dynamics, which present severe non-linearities. The performance of a Kalman filter relies on the ...
Lower Back Injury Prevention and Sensitization of Hip Hinge with Neutral Spine Using Wearable Sensors during Lifting Exercises
(MDPI, 2021-08)
[Abstract] The popularization and industrialization of fitness over the past decade, with the rise of
big box gyms and group classes, has reduced the quality of the basic formation and assessment
of practitioners, which ...
Mobility Evaluation of Wheeled Robots on Soft Terrain: Effect of Internal Force Distribution
(2016-06)
[Abstract]
Many applications of wheeled robots include operations in unstructured environments. Optimizing vehicle mobility is of key importance in these cases. Reduced mobility can limit the ability of the robot to achieve ...
Assessment of Methods for the Real-Time Simulation of Electronic and Thermal Circuits
(MDPI, 2020-03)
[Abstract] Time–domain simulation of electronic and thermal circuits is required by a large array of applications, such as the design and optimization of electric vehicle powertrain components. While efficient execution ...
Direct Sensitivity Analysis of Multibody Systems With Holonomic and Nonholonomic Constraints via an Index-3 Augmented Lagrangian Formulation With Projections
(2018)
[Abstract] Optimizing the dynamic response of mechanical systems is often a necessary step during the early stages of product development cycle. This is a complex problem that requires to carry out the sensitivity analysis ...
Assessment of Linearization Approaches for Multibodydynamics Formulations
(2017-07)
[Abstract] Formulating the dynamics equations of a mechanical system following a multibody dynamics approach often leads to a set of highly nonlinear Differential Algebraic Equations (DAEs). While this form of the equations ...
Performance indicators for wheeled robots traversing obstacles
(2020-04)
[Abstract] An important element of wheeled robot operations on uneven and unstructured terrain is the ability to overcome obstacles. In this letter, we deal with a part of this obstacle negotiation problem. We particularly ...
A Fair and EMG‑Validated Comparison of Recruitment Criteria, Musculotendon Models and Muscle Coordination Strategies, for the Inverse‑Dynamics Based Optimization of Muscle Forces During Gait
(BioMed Central Ltd., 2021-01)
[Abstract] Experimental studies and EMG collections suggest that a specific strategy of muscle coordination is chosen by the central nervous system to perform a given motor task. A popular mathematical approach for solving ...
