Latest company news about Crank Test and Debugging of Bicycle Brake and Road Condition Life Tester

Test action: The bicycle crank test is to drive the front sprocket to rotate through the motor, and the front sprocket drives the rear sprocket through the chain, thus driving the rear wheel of the bicycle to rotate. When the rear wheel of the bicycle rotates, because of the friction between the rear wheel and the roller under the wheel, the rear wheel will drive the roller to rotate when it rotates.

Problems during commissioning: When the front sprocket is driven by the servo motor to make the speed of the rear wheel greater than 5km/h, the chain will break. Through analysis, it is found that the motor acceleration and deceleration time is too short, and the 10S acceleration time is too short. When the running speed is high, because the roller mass is too heavy, the motor acceleration time is too short, and the set running speed is faster, the greater the gradient of acceleration at 10S, the greater the force the chain will bear, When the bearing capacity of the chain is greater than its maximum bearing capacity, the chain will break.

 

Solution: Make an acceleration time that can be set freely on the touch screen inside the program. We can set the corresponding acceleration time according to the vehicle speed. The higher the speed is, the greater the acceleration time must be set. Of course, the larger the acceleration time is set at low speed.

The problem of chain breakage is solved through the above description, and it is verified that the 7-27km/h speed according to the order requirements is completely OK.
