The Design And Fatigue Life Analysis Of Basketball Wheelchair

Along with society's civilization and progress, more and more disabled people participate in social activities with the help of wheelchair. Then sport wheelchair's appearance, not only has shortened the disparity between disable people and normal person, but enabled disable people to enjoy the pleasure of life equally to normal person, importantly provided to them the opportunity of unfolding their own value.The basketball wheelchair is the special equipment for the disabled person to participate in basketball sport. Because the wheelchair basketball is a kind of movement with stronger antagonism, the mutual collisions between wheelchairs are always happen during the match , even causes the wheelchair tipping as well as athletes' being injured. Therefore the basketball wheelchair with fine performance not only provide to the athlete the comfortable sitting posture which adapts with the human body physiology characteristic, simultaneously, but also should have the good stability and the flexibility, both makes athletes obtain better competition result, and may avoid as far as possible the second injury to the athlete from the dashing during the match.Overseas there are many universities and academes engaging in the research on wheelchair for a long time, therefore at present the basketball wheelchair contents higher technology mostly designed and manufactured overseas. In comparison, the domestic research is quite backward. Therefore, it's a duty which has significant and practical meaning to design high quality and performance basketball wheelchair, and let our disabled athletes use homemade wheelchair to participate in international competition and get better achievement.Firstly, according to the research of the present development situation of domestic and foreign basketball wheelchair, and utilizing the Man-Machine Engineering principle, this paper designs a medium-sized basketball wheelchair and a agonistic basketball wheelchair respectively aim at common and athlete. And carries on partially progressive design to the agonistic basketball wheelchair in order to improve it's performance. Secondly, carries on forecasting and analyzing of basketball wheelchair fatigue life by the union of virtual prototype technology and fatigue life analysis software. Through the research on analysis results, finds out the weak links of the wheelchair structural design which affect its fatigue life, and makes suitable improvement to the basketball wheelchair structure.The research of this topic has a more vital significance for enhancing the performance of basketball wheelchair and the development level of homemade sport wheelchair. At the same time, it also makes a contribution for disabled persons' sports enterprise of our country.
