8. the application method of whole bicycle described in claim 1 and individual event fatigue experiment analysis platform, it is characterised in that packet
Include following steps:
Step 1: according to the wheelspan of the front wheels and rear wheels of experiment bicycle, corresponding two sets of wheel auxiliary adjustment mechanisms of adjustment
Spacing, then bicycle is placed into two sets of wheel auxiliary adjustment mechanisms；
Step 2: it is adjusted by placement location of the wheel auxiliary adjustment mechanism to bicycle, until the foot pedal of bicycle
Into in the range of footboard drives mechanism；
Step 3: the position of foot pedal strap in adjustment footboard drives mechanism, it will voluntarily by foot pedal strap
The foot pedal of vehicle is fixed；
Step 4: by the wheel shaft of the front wheels and rear wheels of bicycle respectively with the wheel hub card in two sets of wheel flexibility fixed mechanisms
Button is fixed；
Step 5: the vehicle cross handle fixed ring in vehicle cross handle Vertical loading mechanism is linked together with vehicle cross handle, simultaneously
Three-jaw platen in the multi-direction loading mechanism of saddle is sticked on bicycle saddle；
Step 6: the motor in starting footboard drives mechanism is provided rotary power for bicycle pedal, is moved to pedal with simulation
Make；Start vehicle cross handle Vertical loading hydraulic cylinder and saddle Vertical loading hydraulic cylinder simultaneously, provides lower pressure for whole bicycle, with
Simulate the load of cyclist；It is used for the real work state of analog bicycle vehicle at this time；
Step 7: after whole bicycle reaches preset runing time, motor stopping, while vehicle cross handle Vertical loading hydraulic cylinder
With pressure under saddle Vertical loading hydraulic cylinder removal, check that the degree of impairment of each components of whole bicycle, bicycle are whole
Vehicle fatigue experiment terminates；
Step 8: the company of wheel hub buckle and front wheel and rear axle in two sets of wheel flexibility fixed mechanisms is first disconnected
It connects, is then consolidated the wheel shaft of wheel hub clip and front wheel and rear-wheel in two sets of wheel rigid fastening mechanisms
It is fixed, while the front wheels and rear wheels of bicycle being made to be detached from wheel auxiliary adjustment mechanism；
Step 9: restarting vehicle cross handle Vertical loading hydraulic cylinder and saddle Vertical loading hydraulic cylinder are vertically added by vehicle cross handle
Carrier fluid cylinder pressure individually loads vehicle cross handle, is individually carried out to bicycle saddle by saddle Vertical loading hydraulic cylinder
Load；
Step 10: after the preset load time, vehicle cross handle Vertical loading hydraulic cylinder and saddle Vertical loading hydraulic cylinder are same
When removal under pressure, check that the vehicle frame of bicycle, the degree of impairment of vehicle cross handle and saddle, bicycle individual event fatigue experiment terminate.
