Abstract:
Objective To establish and validate a human comfort evaluation method based on musculoskeletal activity in biomechanics.Methods Firstly,the limitations of current biomechanical-based comfort evaluation method were analyzed.Secondly,a new evaluation method based on musculoskeletal activity was proposed,which considered the influence of muscle and joint on comfort,and a comfort index was obtained.Finally,the firefighter's water belt rolling task was selected for verification.Results The comfort index derived from the improved musculoskeletal activity-based evaluation method was 0.74,which was lower than the comfort index of 0.82 obtained from the comfort based on muscle activity.The verification results aligned with the theoretical analysis.A questionnaire survey conducted on 43 firefighters showed that the subjective assessments gathered were consistent with the verification outcomes,further confirming the conclusion that the former method was more comprehensive and accurate.Conclusions Compared to the method that focuses exclusively on muscle activity,the comfort evaluation method that integrates both muscle and joint conditions not only more accurately reflects the actual state of the human body but also comprehensively identifies potential biomechanical risks,thereby demonstrating greater practical significance.
