| Popis: | 96 The road race bicycle riders always keep the cycling postures as to lower extremities and to lower the back, the neck and upper extremities for reducing wind speed, but the postures also reduce the comfort of the body. In order to solve the problem, the handlebar for the road race bicycle can control the directions and changes the hole to make different postures for reducing uncomfortable, but this method can not reduce the pain in the palms. Therefore, the main purpose is to add the comfortableness to the road race bicycle handlebar. First, adopting analysis of extract on the form feature as the main factors that will cause influences on the orientation recognition, and proceed with the experiment of handlebar’s curve for the result that whether or not the curve effect the comfortableness of the handlebar. Continuing with the comfort experiment of the handlebar area for understanding the palm’s area of pressure and touch, and gather the details of subjective evaluation. Based on the result of the analysis of the experiment, we would be able to estimate the most appropriate size, and with 3D drafting and “Coordinates the Rapid Prototyping” technology for designing new handlebar, and fulfill the final experiment that is used to evaluate the new handlebar’s comfort. Taking the example from one of the results, with the added width and with the camber of human factors fitting in the new handlebar design, and made the areas of touch increased conspicuously, the areas of pressure were reduced. As we compare the old handlebar C with the new handlebar F’s, taking the first experimental position as the example (the upper part of the handlebar which closer to the center of the handlebar). The results showed the palm’s area of touch have 5 negative and 13 positive responses that means handlebar F’s is bigger than C’s, and the palm’s area of pain have the range between 16 negative and 2 positive responses that means handlebar F’s is apparently smaller than C’s. After the combined evaluations, the new handlebar was perceived to be better in comfortableness. |
