Resumen
Este estudio encontró que el rendimiento del exoesqueleto, específicamente el rendimiento del momento, varía significativamente con los niveles de activación y las velocidades de movimiento. Esta investigación ayuda a seleccionar el exoesqueleto adecuado para las demandas específicas del trabajo para prevenir lesiones en la zona lumbar.
Área de la Ciencia:
- Biomecánica
- Salud en el trabajo
- La robótica
Sus antecedentes:
- El dolor lumbar es común en trabajos físicamente exigentes, lo que lleva a altos costos personales y sociales.
- Los exoesqueletos ofrecen soporte mecánico para reducir el esfuerzo físico y el riesgo de lesiones.
- Existen datos limitados sobre el rendimiento del exoesqueleto en diferentes condiciones de trabajo.
Objetivo del estudio:
- Para evaluar cómo los niveles de activación del exoesqueleto y la velocidad angular afectan la salida de momento del plano sagital.
- Para comparar el rendimiento de los exoesqueletos SuitX-backX y Laevo-V2.5.
- Informar sobre la selección de exoesqueletos específicos de la tarea para la seguridad laboral.
Principales métodos:
- Los exoesqueletos (SuitX-backX, Laevo-V2.5) fueron probados en un dinamómetro.
- El ensayo incluyó un rango completo de movimiento bajo varias velocidades de carga (5-60 grados por segundo).
- Los ANOVA de dos vías analizaron diferencias en las salidas de momento basadas en el nivel de activación (alto / bajo) y la velocidad angular.
Principales resultados:
- Ambos modelos de exoesqueleto mostraron diferencias significativas en las salidas de momento.
- El rendimiento varió significativamente entre los diferentes niveles de activación.
- La velocidad angular también tuvo un impacto significativo en las salidas de momento de ambos exoesqueletos.
Conclusiones:
- El rendimiento del exoesqueleto no es constante y está influenciado por la configuración de activación y la velocidad de movimiento.
- La comprensión de estas variaciones de rendimiento es crucial para la selección efectiva de exoesqueletos.
- Esta investigación proporciona datos para optimizar el uso del exoesqueleto para la prevención de lesiones en la espalda baja.

01:20Bending and Torsional Moments
4.3K
Bending and torsional moments are two fundamental concepts in structural engineering. They play an important role in understanding the behavior of materials and structures under different loading conditions.
The reaction developed in a structural element when subjected to an external force causes the element to bend. When a structural element bends upwards, it creates compressive normal forces on the top and tensile normal forces on the bottom, resulting in a couple that determines the bending...

Imagine a rigid body that is rotating at an angular velocity of ω within an inertial frame of reference. Along with this, picture a second rotating frame that is attached to the body itself. This frame moves along with the body and possesses an angular velocity of Ω. The total moment about the center of mass is calculated by adding the rate of change of angular momentum about the center of mass in relation to the rotating frame and the cross-product of the body's angular velocity...

01:12General Case of Eccentric Axial Loading

Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...

01:21Relation Between Moment of a Force and Angular Momentum

In the realm of spinning tops, the application of force at a distance from the center produces torque, a pivotal factor that alters the angular momentum of the top, thereby inducing its rotation. The concept of moment, akin to linear force in rotation, quantifies how a force acting upon an object initiates rotational motion. Angular momentum serves as the rotational counterpart to linear momentum, representing an object's inherent tendency to persist in its rotational state.

The comparability between linear and angular velocities, linear and angular accelerations, and the kinematic equations of translational and rotational motion can be extended to the concept of inertia.
If a rigid body is rotating about an axis but is not in translational motion, its translational kinetic energy is zero. However, since each particle undergoes rotational motion, it possesses non-zero velocity and kinetic energy. Thus, the kinetic energy of the rigid body, which is the sum of the...

The concept of angular momentum for a solid structure is illustrated as the cumulative result of the cross-product of the position vector of the mass element and the cross-product of the body's angular velocity with the position vector.
