Optimization design of adjustable seat in narrow vessel control station based on ergonomics

In the context of the absence of specific standardized procedures for designing narrow vessel control station seats, this study aims to enhance both personnel comfort and operational efficiency within the control station. This research optimizes the design of narrow vessel control station seats based on the following systematic methodology. Initially, a simplified human body model is employed, followed by forward kinematic modeling to obtain and analyze the comfortable range of joint motion data. Subsequently, fundamental parameters and adjustment ranges of the seat are determined based on the analyzed data. Lastly, utilizing the DELMIA anthropomorphic analysis module, a human-body simulation analysis is conducted on the designed chair. Based on the simulation results, further optimization focused on the armrest range of the chair can be conducted. The results demonstrate the efficacy of the proposed methodology in achieving ergonomic optimization in narrow vessel control station seat design.
