The Mechanics Model Problem Construction And Analysis Of A Automatic Powder Pressing Machine

This subject is one part of "automatic assembled and detection technique of the detonator" of the weapon research project. On the whole automatically production produce line, the automatic detonator presses medicine is an essential important component, it is the key technology in the production too, this procedure of our country has been in the artificial or semi-automatic state all the time, restricting the improvement of the automatic level of whole assembly line, the assembling automatically product has become a bottleneck problem.The relevant mechanics problem is a important part to successfully design, this paper will discuss the plasticity limit load of cylinder shell, and it offer the theory assurance of the product assembles and design. This paper analysis the plasticity answer of different thick detonator shell, different powder amount and different load displacement with the finite element method by using ANSYS software package, this offer the theoretical foundation for the security , dependability of the design and use of the automatically assembled, at the same time , it can apply this method to oil field drilling and building while driving pile , this has very great meanings in guiding the actual project.The model of this paper belong to both material and geometry non-linearity, also it is the state non-linearity. This paper compares six different projects, and contrast the different result of the six projects, according to the characteristic of plastic unsteadiness spot, we can supervise the detonator by the strain field, stress field and orientation displacement, this can ensure the quality and the security of the detonator.Column thin shell is widely applied in many industries, but it is a hot problem because of the lack of analysis and design method. So we should go on realize the working character of this kind of component, it can offer more foundation for instruct design.
