Characteristic analysis and reconstruction method of falls from windows

Area of Science:

• Forensic Science
• Biomechanics
• Accident Reconstruction

Background:

• Window fall accidents are challenging to investigate due to lack of witnesses and complex dynamics.
• Existing research on window fall accident analysis is limited.
• Understanding initial fall parameters is crucial for accident reconstruction.

Purpose of the Study:

• To classify window fall accidents based on behavior characteristics.
• To analyze the behavior of falls using multibody simulation.
• To develop a method for specifying accident types using fuzzy logic and simulation.

Main Methods:

• Classification of window fall accident types.
• Multibody simulation analysis using experimental data for initial fall postures and speeds.
• Case studies of real events with fuzzy tool-based reconstruction for type estimation.

Main Results:

• Behavioral characteristics of different window fall accident types were analyzed.
• A simulation-based method for reconstructing and specifying window fall accident types was developed.
• Fuzzy logic was employed for type estimation in case studies.

Conclusions:

• The study provides a classification and characteristic analysis of window fall accidents.
• The proposed reconstruction method aids in specifying accident types.
• Findings are valuable for forensic investigations of window fall incidents.
