本文介绍了ＹＴ２４型气动凿岩机的辅助设计主要方法，同时也介绍了软件的主要功能。在软件设计过程中考虑了消声器、转钎机构以及负载对凿岩机性能的影响，对气道阻力作了详细的计算，在优化过程中采用了惩罚函数法与“比较排除法”共存的方法，即保留惩罚函数的特点，又能够解决工程中的实际问题，是一种速度较快的方法。此软件采用Ｃ语言和ｆｏｒｔｒａｎ语言编程，是一种混合模式的编程方法，软件用汉字菜单进行管理，包括优化设计、数据处理、运动过程模拟和图形处理等模块，软件对产品的性能参数具有测算功能。
This paper introduces the main method of auxiliary design of YT24 pneumatic rock drill, and also introduces the main functions of the software. In the process of software design, the influences of muffler, rotating mechanism and load on the performance of rock drill were considered, and the airway resistance was calculated in detail. In the process of optimization, the penalty function method and the method of “comparative exclusion method” coexisted It is a fast way to keep the characteristics of penalty function and to solve the practical problems in engineering. This software is programmed in C language and FORTRAN language. It is a mixed-mode programming method. The software is managed by the Chinese menu, including modules such as optimization design, data processing, simulation of motion process, and graphics processing. The software has the function of measuring the performance parameters of the product Features.
