Abstract

Objective: This study developed a determination method of representative points in the space of principal components to generate representative cases for anthropometric design and digital human simulation. Background: The advanced generation method using principal component analysis can create a group of representative cases that statistically accommodate a designated percentage of design target users. However, a specific determination method of representative points to generate representative cases has not been proposed in existing studies. Method: This study proposed a determination method of representative points on an n-dimensional ellipse formed in the space of principal components. The proposed method determined representative points on each principal component and on the combination of principal components using an optimization model. The performance of proposed method was evaluated by generating representative cases for anthropometric design and digital human simulation of airplane cockpit. Results: The proposed method selected eight representative points on an ellipse formed to accommodate 95% of design target users in the space of two principal components. The selected points represented one overall small user, two small users with different body proportion, two medium users with different body proportion, two large users with different body proportion, and one overall large user. Conclusion: The proposed method properly determined representative points on an ellipse in principal components. Application: The proposed method can be used to generate representative cases using principal component analysis for anthropometric design and digital human simulation.
