Numerical calculation and analysis of influencing factors on waist force of armored vehicle driver

Abstract

High morbidity of low back pain is a prominent problem for crews in operating armored vehicles. The low back pain of drivers has a direct relationship with the waist force under unreasonable postures. Based on the national military standard (GJB) and national standard (GB), this paper built a biomechanical model of armored vehicle driver’s waist aiming at operation characteristics of armored vehicle driving. Influencing factors on waist force of armored vehicle driver were figured out. Numerical calculation was conducted and the change laws of influencing factors were analyzed, which gave out analysis conclusions. The results obtained from this paper can provide reference for improving waist force of armored vehicle drivers.
