| Vibration is a kind of mechanical movement of objects which exists ubiquitously in nature. It is widely used in various fields, such as mine, metal metallurgical, chemicals, light, steel, and so on. Vibration loading is to put massive, coarse and powder materials into access device from storage silo and funnel by means of vibration. To make ready-made grains densely uniformed, the technology of vibration is applied to the charge crafts of military enterprises, develop a vibration charge system.There main components to bear a long-period alternating load, all kinds of injury and damage, like fatigue failure, will become contributing factors to affect its capacity and life of equipment. The topic here:information of charge system on aspect of deformation and stress distribution are obtained on the condition of vibration with help of dynamic analysis through finite element analysis method and together with simulation as well as analysis of its main parts by software ANSYS 9.0.The thesis elaborates the development history of charge system at military enterprises home and abroad and also the applied conditions of the vibration technology to modern industrial. With software ANSYS9.0 used to establish finite element model of above glide crossbeam, following glide crossbeam and pins respectively, and modal as well as harmonic response analyzed, theoretical quotas are achieved on different working conditions on terms of static stiffness, dynamic stiffness, natural frequency and related mode of main parts of charge system. The article provides theoretical basis for structural design and further optimization of vibration charge system through the analysis of results and verification of whole system reliability. |
