摘　　要：设计了弹丸膛内纵向过载直接测试系统,加工特制弹丸及假引信体,保证其质量、外形、长度与原弹丸及相应的引信体保持一致,保证其与原弹丸及相应引信膛内运动过程相同。采用弹载存储测试技术,将加速度传感器安装在弹丸内部,然后采用软回收技术回收弹体,取出弹载测试存储模块,将弹载测试存储模块通讯串口与微机串口相连,并将弹载存储器存储的数据导入计算机并分析处理,获取弹丸膛内纵向过载动态分布规律。并数值仿真了引信膛内纵向过载,仿真结果与试验结果吻合较好,为引信安全性问题的研究提供了可靠的数据支持,同时也说明了理论仿真的正确性和试验方法的可靠性。This paper machining the special project and the dummy fuze which the mass, externality,length and the moving process in bore are same to the real project and fuze. Using the shell- borne recorder technology,the accelerometer is fixed in the project, then the project is reclaimed. The shell-borne recorder module is put out, then the module and the computer are connected. The dynamic distribution of project longitudinal overload in bore will be obtained by the data of shell-borne recorder is sent to computer and analyzed. Then we got the longitudinal overload of the fuze in bore using the numerical simulation method, and the result of the numerical simulation is well agree with the result of the experiment. It provides reliable data support for the research of the fuze safety problem, and it also show the numerical simulation is accurate and the experiment method is reliable.
