摘　　要：在设计发动机凸轮时，常常以相匹配的成熟发动机凸轮为原型进行。在这一过程中，常常要求推导出原型发动机凸轮型线方程，即发动机凸轮逆向工程设计。文章论述用专业逆向工程软件Imageware进行发动机凸轮逆向工程建模，获得凸轮升程，再用Excel矩阵计算功能，根据最小二乘法原理，精确逼近发动机凸轮型线方程的过程。The design of cam in engine is often used to design on mature cam matched as the prototype. In this process, we often deduction cam profile quotation of prototype engine, namely the reverse engineering of cam in engine. This paper discusses the cam reverse engineering by Imageware that＇s a Professional software, obtain the cam lift, then we can accomplish the matrix calculation by Excel, according to the principle of least square method, we can accomplish the process of approximation cam profile equations.
