Langevin Transducer

Some applications, like force feedback joystick, require force measurement with high stiffness sensor to limit handle oscillations. In this way, this article presents an original technology to measure static force using the resonance frequency variation principle of a piezoelectric actuator subject to preload variation. We present in a first part comparison of various involved technologies to justify our choice (stiffness, inertia.....). The second part deals with the analytical modelling by variational principle of Langevin transducer. A comparison with the numerical FEM results is performed. Experimental results are then reached to validate the detailed concept. They demonstrate the potentiality of static force measurement with classical resonant structure like Langevin transducer with laboratory instruments. A last part is dedicated to the definition of an electronic to supply the sensor and to treat the measure. First experimental results are presented in an open loop electronic power supply configuration.
