Manufacture Of Bicycle Vehicle On Testing And Its Diagnostic Software On Pedalling Technique

To advance the science of bicycle training ,it is necessary to supervise,test and feedback the athlete's individual techniques. In defect of such an controlling instrument and method in our country ,therefore, a testing bicycle has been developed in this experimentation according to the demands of current bicycle training .5 sporters of bicycle and 6 pastime bicyclers were tested and their techniques were analysed .especially ,the saddle orientation of racing bicycle were diagnosed solely for the athletes participating in the this test.This study found some disciplinarians ,Provided some indexes on how to analyze shortcoming and merit about pedalling techniques and some beneficial suggestions for training,built up a set of software integrated with collecting data,processing, storing and rewinding.An important step was strided on Bicycle For Human Being and a base was underlayed for exploring ,feedback and supervising the techniques of riding on bicycle in the future.conclusions as follows:(1)The existence on the driving phase in the recovery course has been corroborated. however,a new cognition was put forward about the technical essence of pedaling, which thinks that the effective pedaling techniques isnnt for producing driving force but for ensuring the need of Tache chain of lower limbs spanning TDC rapidly and steadily in the course of recovery phase.The study thinks that increasing positive moment during the driving phase takes on more responsibility than decreasing negative moment in the recovery phase especially in the condition of high-power output.(2)The study approved the validity of two theories.The first is the angular velocity 0f crank in the recovery phase should bigger than driving phase ones, the second is the consistency on the theoretic analysis of knee and ankle joint tracks and practical results(3)Saddle orienting scope for the objects participating this experiment were conformed primarily ,namely Seat angle should be >72。and seat height be≥106%TH for the bicycle- athlete and 72。Seat angle and 101%TH be considered the better orientation for recreation bicyclers.(4)Five indexes using in diagnosis for pedalling techniques were decided .The first is the angular velocity 0f crank in the recovery phase should bigger than driving phase ones.The second is the scopes of TDC in the different combinations.The third is the average efficiency of the driving phase during the different combinations.The fourth is overlapping degree ,lubricous degree, symmetry and unsymmetry of knee and ankle joint track.The fifth is the equilibrium in strength of the left and right leg in the course of pedaling.(5)There are two discoveries in the experiment. One is invariablenes basically about bending and extending scope of thigh angle during the pedaling which tells us the strength training method of improving stretching power of coax joint related to bicycle athletes, namely bending and stretching angle Of thigh must be controlled in 30。-85。while Pursuing strength training.The other is the rate between thigh length and effective calf length is one of the important factors influencing bicycling which can provide important references for selecting the bike sporters.(6)The study built a set of diagnostic software on pedalling technique, which can obtain Synchronously kinematic parameters of lower limbs taches and kinetic parameters of pedal, handle and saddle at any moment during the pedaling.Then, kinetic parameters Were combined with related to angle which shall produce effective force and efficient index through related to software. Diagnostic software can achieve the Comparison Of pictures and characters between the general and high-grade athletes and among the outstanding athletes so as to search individual differences in pedaling techniques ,which will bring many benefits for advancing the competitive bicycle.
