摘要
依据工程教育专业认证标准中对复杂工程问题的特征分析,就当前单个课程实验中涉及解决复杂工程问题能力培养方面的环节较少或不足等现状,结合北京信息科技大学测控技术与仪器专业"光、机、电、算"综合性应用型人才的培养目标,以凸轮设计课程实验为研究对象,通过分析课程实验现状,改进与优化实验内容。从实际工程问题出发,引入压力角与基圆半径间利益冲突来约束参数选择,运用机械原理和计算机仿真等技术,抑制凸轮机构的运动冲击,并将其在内燃机配气机构工程场景中进行实例化,有效提高了其整体性能,并节省了设计、制造及调试成本。初步应用表明,该教改方案有效提高了学生对复杂工程问题的解决能力,同时对测控专业工程教育认证水平的提高具有积极的促进作用。
To improve undergraduate’s ability training of solving the problem of complex engineering in the current individual course experiment,we analyzed the characteristics of the problem of complex engineering according to the accreditation standards for engineering education,and combined with the our talent training goal which is gathered with optics,mechanics,electronics and algorithm.And then an experimental teaching reform of cam design,which is an individual course experiment,was explored in this paper.By analyzing the current situation of the course experiment,its experimental contents were improved and optimized.From practical engineering problems,this paper introduced a conflict between pressure angle and radius of base circle to select parameters in cam design process,and applied mathematics,mechanical principle and the computer simulation to inhibit the impact of cam motion.And of all that we had improved in the experimental process of cam design,were instantiated into a valve mechanism of internal combustion engines,a typical engineering application.The preliminary application shows that the new experimental teaching reform of cam design effectively improves the undergraduate’s ability of solving the problem of complex engineering,meanwhile,it has an great improvement on the level of engineering education accreditation of measuring and controlling technology specialty.
