【 摘 要 】

Meсhanoluminescent sensor is a solid-state optoelectronic light-generating pressure transducer, which directly converts mechanical impulse into optical signal. Such sensors can be integrated into systems with fiber-optical lines, the latter being intensively used in an environment with intensive electromagnetic interference and high explosive danger. There is a proposal to use mechanoluminescent sensors in the robot tactile sensing systems that are used in extreme operating conditions. Mechanoluminescent sensor-based grippers are capable of providing information about the presence of the manipulation object, its shape and size, as well as its holding force. An informative sensor output signal is converted and processed according to a specific algorithm, which is based on a mathematical model of mechanoluminescence. The mechanoluminescence effect displays itself when luminescent centers interact with the moving dislocations accompanying the deformation process. The proposed mathematical model describes the mechanoluminescence effect for different luminescent centers, activating mechanoluminescent material – belonging to intracenter and recombination type. The model allows us to calculate the output optical signal parameters of the sensor depending on the parameters of input dynamic pressure. A range of the input pressures corresponding to the maximum values of the mechanoluminescent sensor signal was determined by simulation. The most intense signal is observed in case of a pulse load. The proposed mathematical model can be used in evaluation of the reverse transformation that is to determine the parameters of the input mechanical impulse corresponding to the output optical signal of mechanoluminescent sensor.
