Empirical Modeling of a Squeeze Film Haptic Actuator
In the analysis of squeeze film haptic tactile feedback actuators, attention is focused on establishing an empirical model of the force generated on the user's finger. The model is based on finite-element simulations which take into account the real motion of the actuator. As analytical models exist for very few special cases, a methodology is exposed to establish an empirical model of the force created between a finger and an actuator aided by an optimal design-of-experiment plan. Then, an example of an actuator which generates a sinc profile amplitude of vibration is treated.
