本教材缩编自M.F.Spotts，T.E.Shoupand L.E.Hornberger编写的《Design of Machine Elements》（8fhEdition）。该书内容丰富，大部分内容适合我国机械类本科生的教学要求。原教材共15章，不仅包括典型机械零部件的设计方法，而且还包括工程力学、工程材料、形状综合原理和塑料零件的设计等内容。为和我国目前高校机械基础课程体系中机械设计课程的内容相衔接，以便于各类读者使用，编者对教材进行了重新组织和缩编。现包括9章内容，包括机械设计概论、基本应力分析和失效理论、轴的设计、弹簧、螺栓连接和螺旋传动、带传动、离合器、制动器和链传动、润滑、滚动轴承、直齿圆柱齿轮、斜齿轮、锥齿轮和蜗杆传动。从删减的内容看，其内容或是与我们的课程关系不大，或是在其他课程里已经学过。对于原书中丰富的习题，根据保留的基本内容进行了相应的删减。另外，原教材为读者提供了一些基本的工程力学计算、典型零部件的设计程序。为与纸质教材相关内容相一致，没有改变原程序中的模块编号。本教材可以作为英文或双语教学用机械设计课程的教材，也可供机械工程专业本科生、研究生或其他从事机械设计工作的专业人员参考。
