Research On Key Technology Of Fuze System Characteristic Parameter Testing

A certain type of fuze plays a key role in the actual working process of the missile,and its excellent performance can not only ensure the safety of the missile,but also provide guarantee for the missile’s strike accuracy and killing effect.Fuze test equipment can accurately and comprehensively test the performance indicators of the fuze to ensure the reliability and stability of the fuze in actual use.Therefore,in the development and production of fuses,the importance of fuze test equipment is self-evident.Traditional test equipment has narrow coverage and low testing efficiency.Therefore,the development of automated test equipment for fuses is extremely necessary.The main research work of this thesis is as follows:1)The hardware design of the automatic test equipment for electronic time fuze is completed.Aiming at the problems of less types of traditional test equipment,lower test accuracy and complex operation,an integrated test system for electronic time fuze is developed.The system can not only test multiple types of fuzes,but also conduct multiple asynchronous tests of up to 15 channels at the same time.It also adopts distributed and modular design,which is easy to install.The test system consists of test device and test terminal,including computer,programmable power supply,PCI board,communication cable,etc.According to the function of the system,the hardware part of the equipment mainly includes the main control module,data acquisition module,power module and test terminal control module.2)The software design of the electronic time fuze automatic test system is completed.Based on the test requirements,the fuze test software based on Lab VIEW platform is designed and developed.VISA,TDMS and other technologies are applied in the design of the test software,realizing the functions of automatic test,communication transmission,signal processing,test result analysis,data storage and so on.The friendly interface greatly improves the testing efficiency.3)The application of queuing model in multiple-channel asynchronous data acquisition is completed.In the scenario of multi-channel asynchronous real-time data acquisition,this paper applies the queuing theory model M/M/1 model in modern communication,and optimizes the parameters of the model according to the data processing performance of the test system,which ensures the accuracy of the data acquisition process and meets the requirements of multi-channel asynchronous test.4)The research of error tracing and correction method is completed.In order to compensate the error of the testing system,the measurement scheme is designed and the measured data are statistically analyzed.The corresponding correction method is selected for the possible error sources to compensate the error.5)The optimization algorithm of characteristic parameters of electronic time fuze is studied.For the two characteristic parameters of ignition voltage and ignition time,the ignition voltage optimization method based on fractional polynomial fitting algorithm and the ignition time optimization method based on constant ratio discrimination timing algorithm are selected respectively to further improve the test accuracy.After design and debugging,this automated test system for electronic time fuzes has been developed and put into use.The results show that the test system has comprehensive functions,stable performance,accurate testing results,meets the design requirements,and has achieved the expected development goals.
