This master thesis deals with the design of a handbike with electric propulsion. The final design is created in regard to knowledge from design and technical analysis and also to desficiencies of contemporary products. The purpose of this work is to create design of electrohandbike which will respect user and his needs from ergonomical and esthetic point of view.

Essa pesquisa apresenta um triciclo inovador para pessoas com paraplegia ou alguma deficiência motora dos membros inferiores, desenvolvido com duas forma de acionamento: cíclico manual (handbike) e elétrico. A estrutura tubular foi elaborada com liga de alumínio 6063 - T5. A plataforma ANSYS Academic versão 19.2 foi empregada para uma análise estrutural do chassi do equipamento. O chassi foi submetido num ensaio de carregamento estático progressivo de até 1200 N aproximadamente. O deslocamento onde apoia os pés do usuário foi medido por um relógio comparador de precisão de 0,01 mm. O deslocamento da plataforma inferior de apoio dos pés apresentou uma divergência de aproximadamente 4% se comparado com os dados obtidos pela plataforma ANSYS. Assim, validando a análise teórica pela plataforma ANSYS e confirmando que a estrutura fabricada por dobramento e solda TIG suporta com segurança um usuário de até 100 kg. Parâmetros relacionados ao sistema elétrico de acionamento do motor brushless de 1000 W foram obtidos por meio de sensores de corrente e voltagem, assim como parâmetros de desempenho mecânico foram obtidos empregando uma célula de carga de fundo de escala de 2kN para análise de força de tração e um sensor de velocidade. Os resultados indicam uma...

This research presents an innovative tricycle for people with motor deficiency of the lower limbs, developed with two forms of drive: manual cyclic (handbike) and electric. The tubular structure was made with 6063 - T5 aluminum alloy. The ANSYS Academic version 19.2 platform was used for a structural analysis of the equipment chassis. A static loading test of up to 1200 N was performed on the chassis. The deformation of support the user's feet was measured by a dial gauge with a 0,01 mm precision. The deformation of the lower footrest platform showed a divergence of approximately 4% when compared to the data obtained by the ANSYS platform. Thus, validating the theoretical analysis by the ANSYS platform and confirming that the structure manufactured by TIG welding safely supports a user of up to 100 kg. Parameters related to the electric drive system of the 1000 W brushless motor were obtained by means of current and voltage sensors, as well as mechanical performance parameters were obtained employing a load cell of 2kN for force analysis and a speed sensor. The results indicate an energy efficiency of the equipment of up to 92%. The maximum strength of the equipment is 500 N, which makes it possible to perform a climb with slope of 20º, approximately considering a user of 8...

Title: Changes in preparation exercises in handbike riders training Objectives: The aim of work is to collect and systematically process available information about sports discipline handbike and thereby expand knowledge about the theory and sport practice especially to persons with physical disabilities Methods: Implementation of data collection was accomplished through semi- structured interview (interview with instructions). Information gathering was carried out by one-time survey (testimony) of respondents. There was carried out repeated terrain inquiries of the respondents, followed by evaluation of statements. Results: Findings of this work form information about sports discipline known as handbike and allow insight into the issues of this sports industry. Primarily it deals with the material aspects and implementation of training program. Findings of this work can be used to popularize handbike discipline. Keywords: Sport for people with special needs, physical disability, handbike, handcycle, handicap, sports training.
