| Abstract |
The process of the penetration of thin aluminum alloy plates which are widely used in satellites by conical projectile nose is studied in this paper. A new method of internal capture by flying anchor is proposed to capture and remove large space debris in this paper. The key problem to be solved in this method is the vertical and oblique penetration of satellite surface materials. According to the actual failure shapes, two theoretical models, the petal failure model of vertical penetration and the petal failure model of oblique penetration, are proposed by means of energy balance. For a thin aluminum alloy plate, where petal failure always occurs after penetration, the energy consumption of deformation region of plate involves the deformation energy of cylindrical wall, the petal tearing energy and the petal bending energy. The Thomson's theory is used to calculate the plastic deformation energy of the cylinder wall. Dugdale's narrow band theory which assumed that the width of the plastic zone near the crack tip is similar to the plate thickness is used in the calculation of petal tearing energy. For vertical penetration and oblique penetration, the shape of deformation region is circle and ellipse respectively. In the study of petal failure model of vertical penetration, the effect of half-cone angle on fracture stress is studied by numerical calculation using ANSYS Explicit Dynamics. In the study of oblique penetration, the functional relationship between deflection angle and initial obliquity angle is proposed through numerical calculation. Through the theoretical models, the energy consumption of target plate failure is calculated, so as to calculate the residual velocity or ballistic limit. Tests conducted on common aluminum alloy plates with a thickness of 2 mm. For most aluminum alloy targets, the experimental results are in good agreement with the theoretical results. |
