摘要为了解决现有部分引信存在的发射环境适应性差、不具备撞击安全距离特性、无自毁及自绝火特性、延期解除保险距离短、弹道炸等问题，从而提高引信通用能力、安全及作用可靠性，在广泛调研国内、国外相关研究成果的基础上，设计该中大口径榴弹弹头机械触发引信。18968
首先通过系统分析，论证该引信的工作原理，从而设计该引信的总体结构。而后进行引信各部分结构设计，包括传爆序列设计、保险与解除保险装置设计、装定装置设计、引信用弹簧计算与零件强度校核等。最后绘制了二文图和三文图，对设计所涉及的强度、性能和弹簧抗力等进行了计算。
该引信重量1160 g，最大外径66 mm，最大高度150.1 mm。
该引信通用能力较强、发火可靠性高、发火方式多、有自毁特性、延期解除保险距离较长、具备撞击安全距离特性、发射环境适应性较好，符合GJB 373A-1997《引信安全性设计准则》要求，具备工程设计价值。

Title With warheads mechanical trigger fuze of large caliber
systems analysis and design
Abstract
To solve the existing part of fuze the environment is a flexible, not have a safe distance from the impact special, not have ruin and self and the features and has been put off the distance short questions, thus enhance the capacity to the fuze.
the reliability of Role and security, in extensive research, both at home and abroad on the basis of the relevant research，in designing the warheads mechanical trigger fuze of large caliber.
The first systematic analysis, argument works of the fuze, the overall structure designed to the fuse. And after the fuse the various parts of the structural design, including to design the sequence of Explosion, in designing the device of insurance and lift insurance, in designing the regulating device, calculation the tension of fuze and check the parts strength and.
Finally drawing two-dimensional designand three-dimensional image, intensity，performance and spring resistance in the related design calculated.
The fuse in weight is 1160 g, the largest external diameter is 66 mm，the most highly is 150.1 mm.
The general is able to fuze, With the high reliability of explosion, the way many to explosion, have the function of destroy themselves and themselves have lost working abilities, put off the distance from a longer, have the features about safe distance of impact, have a good adaptability to the environment abuot launch, suffice the relevant requirements about GJB 373A - 1997<fuse with the security requirements of design principles>,
has the engineering design value.
