自行车稳定性问题的研究与诠释

Research and Interpretation on Bicycle Stability Issue

根据刚体转动的力矩平衡,从转动相对定点悬空的角度,给出自行车“转弯不倒”的约束关系,并由此剖析自行车在微小扰动情况下,能够自动恢复稳定的原因.最后,结合自行车转弯过程中的转动惯量及回转半径,给出自行车在“转弯不倒”条件下的最大角速度解析式.

According to the rigid body rotation moment balance,from the Angle of rotation relative fixed- point dangling give bicycle turn ＂fail＂ constraints,and analyze the bike under the condition of small disturbance, automatically restore stability. Finally,the maximum angular velocity resolution of the bicycle in the condition of ＂turn down＂ is given by the rotational inertia and the radius of rotation.
