Ergonomics in the design of magnetron exercise bikes Cai Qinghua Wang Jicheng (Department of Industrial Design, School of Mechanical Engineering, Donghua University, Shanghai 200051, Intensified knowledge, fitness equipment has gradually become a public fitness equipment from the athlete's specialized North training equipment. But existing Most of the fitness equipment can not meet the sports physiological and psychological requirements of the general public.According to the ergonomics theory and the human body size standards in China, using the standard human body template, the author analyzed the design of the main structure of the magnetic control exercise bike, including the human body. The comfort of sitting, the control range of the upper limbs and the movement characteristics of the lower limbs.Human ergonomics (human factors or ergonomics) is a discipline that has emerged in recent years. It studies and analyzes the relationships between human-machine relations, human-machine interfaces, and people and the environment; Psychological and physiological factors in the labor process; operating range, operating force, energy consumption, and fatigue of Dingzuo; information transfer, operation control, and other issues related to human-machine interaction in product development, design, manufacturing, and management (unit: mm ) Grouped measurement items \ number sitting posture before the upper extremity sitting posture upper extremity functional elongation due to The size of each part of the body varies from person to person, and the working posture of the body constantly changes with the operation object and work situation, so it is difficult to theoretically solve the problem of the position of the human-computer related.However, if the human body structure is utilized With the relationship of scales, a variety of standard human form templates are made to analyze the relative position relationship between humans and machines, and the relative design parameters of human-machine relative can be obtained intuitively to provide reliable conditions for the rational arrangement of human-machine systems.GB/T 1575995 Standard Provides the size data and graphics for the design of the human body form template, which is based on the naked body size of the wearer, and is divided into four levels according to the height of the human body, and the first level is the female's/Vth percentile height; Percentile height of women and the 5th percentile of the height of men's corpse. Overlap height of 95th percentile of women's corpse and 5th percentile of men's P5thile. Level of 95th percentile of men's corpse. The number of heights.3 The design of the magnetron exercise bike The magnetron exercise bike simulates the movement of a bicycle, so its structural design can also refer to the design of the bicycle structure. It is impossible to completely imitate the structure of the bicycle.The following focuses on the analysis of the main structure of the magnetron fitness car that meets the human-machine X-programmology (see)... ii U. The design of the pedal platen crank The design of the pedal crank can refer to the magnetic control of the 0-segment vehicle. Exercise bike design model pedal crank structure.As we all know, when a person is riding a bicycle, the pedal crank movement is equivalent to a person walking in a natural state.The so-called ergonomics, is to make people in the operation of the state when the closest The human's natural state, therefore, can be concluded that the ideal length of the crank's movement diameter is equal to the walking length of the person in the natural state.Adults in China in the natural state F walking step length is about 300~400mm. The range of the length is 150200mm. Generally, the median value is 170. The two main parameters involved in the seat cushion are the tilt angle and the length adjustment range. Firstly, the tilt angle is analyzed. As shown, the trainers use the planes of the thighs, lower legs, pedal cranks, and seat cushions when exercising in an exercise bike.ç¬ Determine the tilt angle of the seat cushion and take the extreme position (as shown). That is, the leg of the trainer is straight and the pedal crank is in a horizontal position. According to human physiological characteristics, a angle can not be greater than 90 degrees. Take the first-level human body form template provided by the GB/T15759~"95 standard. The // in the figure is the perineal height. Take a and there is, A75.8°. But according to the stress situation, the ideal angle of the evening angle is 90°. The smaller the household angle, the higher the strength requirement for the material of the mast, so take = 75°. Determine the tilt angle of the mast; after 0, the range of adjustment of the length of the cushion rod can be determined. The range of mat height adjustment, its value range should be between the level of the human body template standing perineal height and the level of the four human body template standing position perineum height, ie 673mm;j
