In this paper, the automatic analysis system of the main beam, which is a critical component of Horizontal Directional Drilling, has been developed based on optimal design theory, modular, packaging tech- nology, the advanced commercial software ANSYS and embedded APDL. In this system, the processes, such as the modeling analysis and optimum of main beam are automatically completed. Through this system, the whole operating conditions and the minimized thickness of main beam about Horizontal Directional Drilling can be easily achieved. Thus, the design object of energy saving, material saving and environmental protec- tion can also be realized, The systematic reliability and rationality are also put to the proof by some exam- ples. This system has the merits of design process such as modeling, analyzing and optimization, automation, friendly interface and easy operation, which is an effectual idea and means to solve complex mechanical component design. The design efficiency and design level of designers can be widely increased.
