Abstract:
Because the pressing powder control process of loading materials for
initiating explosive device exists serious nonlinear and time-varying
problem, and is difficult to establish the accurate model after
analyzing its pressing powder characteristic, a new method with a linear
buffer is proposed to reduce the control difficulty, to improve the
object characteristics and to enhance the control effect of powder
pressure, quality and consistency of initiating explosive device. In
addition, other functions of linear buffer are analyzed in the automatic
powder press process of loading materials for initiating explosive
device. The linear buffer is calculated using ANSYS finite element
method, and the calculation is agreement with the experimentation. It
can be used to instruct and improve the design of linear buffer. The
real application of linear buffer in automatic powder press of loading
materials for initiating explosive device demonstrates that this new
method is valid, and the density consistency of initiating explosive
device is improved efficiently, and will prompt the automation producing
level of aerospace initiating explosive device.
