This article researches the effect of vibration on self-locking and advances the concept of dynamic self-locking. First of all,we make a fairly detailed analysis for the subject on self-locking of a body upon an in-clined plane when the inclined plane has a simple harmonic vibrationalong an arbitrary definite direction. Corresponding condition for dynamicself-locking is established, its geometric and physical meanings are ex-pounded, and some laws concerning dynamic self-locking are revealedfrom this condition. According to above-mentioned condition, the limitingstate diagram for dynamic self-locking of a body upon an inclined planeis drawn out; it gives an audio-visual geometric graphing to the dynamicself-locking condition established. Lastly, on the basis of this diagrama graphic analysis method is developed, and the said subject on dynamicself-locking of a body upon an inclined plane may be perfectly solved bymeans of a simple drawing.
