Leversloopanalyse

Leversloopanalyse is a term used in engineering and biomechanics to describe the systematic study of lever-based mechanisms as they move through a closed or semi-closed sequence of motions. The analysis focuses on how input movement and forces are transformed into output movement and loads across a lever system, with attention to mechanical advantage, efficiency, and range of motion. The concept is applicable to both artificial mechanisms and biological limbs that operate as levers.

The methodology typically combines kinematic and dynamic assessments. A model of the system is built, including pivot points, link lengths, applied forces, and constraints. Kinematic analysis determines displacements, velocities, and accelerations of the lever and joints over time, while dynamic analysis evaluates torques, forces, and energy transfer using Newton-Euler or Lagrangian formalisms. When possible, experimental validation is performed through motion capture, force measurements, or other sensors. Modern workflows often employ computer-aided design and multibody simulation to explore design variants and predict performance.

Key concepts in leversloopanalyse include the lever arm or moment arm, mechanical advantage, fulcrum placement, and loop closure in the motion sequence. The analysis aims to identify bottlenecks, optimize efficiency, and ensure that the mechanism meets safety and ergonomic requirements. It is used in designing tools, climbing or lifting devices, robotic actuators, and rehabilitative or assistive devices, as well as in studying human movement where limb segments function as lever systems.

Note that the term can appear in various Dutch-language engineering contexts and may be used with slightly different emphases depending on the field. See also levers, lever principle, kinematics, and multibody dynamics.
