Embodiment

[0053] The parameters that can be tested in this experimental system are shown in Table 1.

[0054]

[0055] Table 1

[0056] 1. Measure the speed of the front wheel. During the movement of the bicycle, the front wheel is rotating, and the transmission gear transmits the rotational speed to the encoder. The encoder converts the speed into a square wave output per unit time through the internal optical counter, and counts the square wave , the current front wheel speed can be measured;

[0057] 2. As above, the rear wheel speed can be measured;

[0058] 3. Measuring the effect of movement speed on body side balance. Adopt the rear wheel drive method, gradually adjust the motor speed to A, and record the body posture measured by the gyroscope. Similarly, adjust the motor speed to B, and record the body pose measured by the gyroscope. By analyzing the pose changes at different speeds, we can know the influence of speed on the side balance of the vehicle body. Multi-level ...

Abstract

The invention discloses an unmanned bicycle function testing experiment system. The unmanned bicycle function testing experiment system comprises a balance control bicycle model, a bicycle body stabilizing control system, attitude testing devices and a system balance state monitoring and analyzing system. The attitude testing devices are mounted on the balance control bicycle model, and the balance control bicycle model is controlled by the bicycle body stabilizing control system through wireless signals, transmits wireless signals to the bicycle body stabilizing control system and provides real-time parameters of the bicycle body attitude testing devices; meanwhile, the bicycle body stabilizing control system transmits the obtained real-time parameters of the attitude testing devices to the system balance state monitoring and analyzing system in a wireless mode; the system balance state monitoring and analyzing system integrates and analyzes data for studying the bicycle body balance control principles The unmanned bicycle function testing experiment system can provide a testing platform for students major in automation, detecting techniques, control engineering, robots, machine vision and the like.

Description

technical field [0001] The invention relates to an experimental system for automatic control and detection technology, in particular to an experimental research device for automatic control, stability analysis and motion state detection of a bicycle, belonging to the technical field of balance control system test equipment. Background technique [0002] Bicycle is a very convenient means of transportation that everyone is familiar with. It can be said that it is one of the most successful human-powered machines invented by mankind. Since its invention in the 18th century, the bicycle shape, transmission and auxiliary devices have undergone continuous innovation and development, and finally formed the current model. Along with the changes of bicycles, human research on its working principles has never stopped, including the most accepted gyro effect, front wheel trail effect, and centrifugal force. However, the mechanism for bicycles to maintain balance has not been thoroughl...
