计算机辅助设计矩形管孔型

Rectangular Tube Pass by Computer-aided Design

提出计算机辅助设计矩形管孔型的设计思路和计算软件，使矩形管孔型设计有了理论依据，较旧的箱式孔型辅助设计有所突破，由于运用了计算机辅助设计，数据调整方便，精确度高，便于推广应用。

his paper puts forward the design thought and calculation software for the rectangular tube pass by computer-aided design, having both theory basis for designing the rectangular tube pass and new breakthrough for the old aided design of box-type pass. Because the computer-aided design has the data adjustment, convenient revision and high accuracy, it is easy to recommend for use.
