An Experimental Evaluation Method for Mechanical CAD Task of Students

Nowaday, it is more and more popular for college students to undertake mechanical design by means of CAD. In order to evaluate this task, we worked out a plan for transmission shaft design, which was compiled into special program. Based on the plan, an experiment oriented mechanical design task of student was initiated, and a quantitative analysis was employed to evaluate the task. By test, the correlation between mental workload and experimental evaluation method is significant, The result of experiment showed that this evaluation method is feasible and effective.
