Abstract:
According to the theory of the collision analysis, the art icle applies the unit pulse response funct ion mat rix , derives the dynamical equations of multipoints impact s betw een the elast ic system, and reveals the important role of the system dynamical characteristics in the impact s process. T he equat ions obtained in the art icle include the influence of the system original impact s. The equally-ef fective elast ic analogy was used for the local deform of the mult iple impact point s, thus forming the contact non-linear elementary associat ion closed equat ions w ith the dynamic equations. The solut ion to the set of equat ions is expounded and the tree-point impact is analyzed by concrete example, obtaining a good agreement w ith experiment s. The method is of definite reference value for the st rength analysis and movement of automat ic machines of the automat ic w eapons.
