Abstract
|
Shape memory alloys have excellent shape memory effect ( SME ) and superelastic ( SE ) ??effects , thus being more and more attention in the fuze design . Shape memory alloy wire , spring in the fuze safety system for insurance piece , because of its small size , light weight , fuze mechanism can be simplified ; noise-free start, because of its non-magnetic, is not affected by the force of the external environment safer , in a variety of ammunition ( with power supply) or can provide heat fuze has a certain application prospects . The basic characteristics of the papers from the study of shape memory alloys , the theory of shape memory alloy constitutive relation and trigger mode , the shape memory alloy wire tensile test , the results obtained with numerical simulation using MATLAB theory The results were compared . Memory alloy spring electric drive deformation experiments on the basis of detailed discussion of the design methods and mechanical properties of the shape memory alloy spring to get a series of performance curves and shape memory alloys are summarized in Note use . Finally, the idea of the shape memory alloy Trajectory Correction Fuze insurance application , combined with some specific theoretical model , given the design of the fuze insurance agencies and related experimental and analytical methods . The experimental results show that the shape memory alloy has the shape memory effect and superelasticity , which makes the shape memory alloy Application of considerable significance in fuzes , the prospects worth the wait .
