摩托车排气管的设计方法

Design of Exhaust Pipe for Motorcycle

由于摩托车结构比较紧凑,摩托车排气管的设计既要保证安装的尺寸要求,又要使排气管尽可能在一个平面内弯曲,以简化加工工艺。介绍了原始设计方法(试弯测绘法)、传统设计方法(解析法)、近似设计方法(作图法)和使用计算机进行设计作图法等四种设计方法。其中使用计算机与作图法相结合进行排气管的设计最为方便,也最准确。对上述四种设计方法进行了对比,并以江西赣江机械厂近期开发设计的GJ250两轮摩托车为例简要地介绍了使用计算机进行设计作图的方法。

Compact structure of motorcycle requires that the design of exhaust pipe should maintian the mounting demensions and enable the pipe to bend in a plane,so as to simplify the processing. Several design methods in terms of analytic method, approximate design and CAD are intorduced hereof which CAD is considered to be the simplest and most accurate one in case of combining the approximate method. Comparisons have been done for the said methods. And the exhaust pipe design by the combination methods for a two-wheel motorcycle has been taken as an example.
