On the noninterference moving condition of the cages of the vertical circulating parking equipment;

The author of this article derives the interference condition on two light sources from the light vector,discusses the relation between interference condition and degree of coherence in terms of the visibilitg and degree of cohernce ,and obtains the additional condition on clear intertference tinge .

We have solved the arm motion interference coming after the scaling-down design of handle, and given a new way of articulated coordinated control to ensure the trace control.

The paper studies motion interference problem of T-type lifting mechanism from the perspectives of kinematics and dynamics, establishes simulative model of T-type lifting mechanism considering motion interference, analyzes the change of cylinder thrusts when the interference happens, and finally develops design module of T-type lifting mecha.

Geometric method is used here to analyze the knife-edge movement interference phenomena and the change law of knife gap in double-drum crop flying shear,and approaches to avoiding knife collision and determining the original knife gaps.

In the method,a fixed axis gear train is described with a mesh matrix,a clutch matrix and a transmission matrix;movement interferences are identified by the rank of the transmission matrix;and the transmission routes are obtained with a depth-first search(DFS) strategy in the transmission matrix.
