Abstract：To investigate the impact of occupant size differencesand mutual interactions on the far-side occupant insidepolecolisions involving electric vehicles，thisstudyuseda 5th percentile femaleas the nearside occupantand a 5Oth percentile male as thefar-side occupant，and constructed various simulation scenarios byaltering the colisionangleand position.Alinearfiting method was employed to numericallyanalyze the kinematic responses and head and neck injuries of the far-side occupant under different colision conditions.The results show that with thecolisionangle increasing，the lateral displacement of the far-side occupant increases，therestraining effectof theseatbelt weakens，and theoccupant is more likely tocolidewith the near-sideoccupant or themselves.When the collisionangleexceeds the predicted AlS injuryrisk surpasses 50% .The Head Injury Criteria （HIP） values indicate that，inallcases，the head absorbsasignificant amount of energy，suggestinga high riskofAlS traumatic brain injury for the far-side occupant.Neck anterior longitudinal ligament （ALL）injuries predominantlyoccur in high-anglecolisionsandarecorrelatedwith the collisionangle.Aditionally，theposterior longitudinalligament （PLL），capsularligament （CL）and interspinous ligament （ISL） showa significant risk of neck ligament injuries inalmost all cases.
