Estimación de seguridad en el uso de una bicicleta convencional para la generación de energía eléctrica

Abstract

The need to find alternative energy sources brings with it the use of new sources of generation, such as conventional bicycles. In this sense, the question arises as to how safe it is for the user to use this means of transport in generation. The present work consists of the estimation of a parameter of easy evaluation, for the safe use of a conventional bicycle in the generation of electrical energy. The generation of energy is achieved by coupling a bicycle to an electric alternator and this to an inverter, the load used consists of a 100W lamp. The measurement of non-physiological parameters such as vibration, ambient temperature and pedaling speed, together with physiological parameters such as heart rate and body temperature were used to determine physiological and electrical signals when there is overexertion in the user-bike interaction. A protocol oriented to two routines was defined to evaluate the use of the bicycle in conditions of maximum security. Effort and safe operating conditions. Eight people between the ages of 22 and 32, body weights from 56 kg to 80 kg and heights from 1.59 m to 1.84 m. Voltage and current readings were taken to estimate the power and energy generated by the participants. In the process of user-bike interaction it was found that when the participant made an excessive effort, he resorted to compensatory postural movements to maintain the pedaling speed. These compensatory movements made it possible to observe a relationship between vibration and heart rate.
