Análisis mediante un modelo estadístico del comportamiento en la distancia de frenado de los dispositivos de absorción de impacto instalados en los elementos elásticos de tipo espiral

Abstract

The study examined how Növin suspension impact absorbers influence vehicle braking distance according to the United Nations ECE (Economic Commission for Europe) 13-H standard. Panic braking tests were conducted at 100 km/h for M1 and N1 vehicles. Using R Studio, a regression model was developed that explained 99.98% of braking distance variation based on speed and braking. Model validations confirmed its robustness, including tests for normality in regression residuals (p = 0.6426) and homoscedasticity (p = 0.6252). Multicollinearity among variables was assessed using variance inflation factor analysis (VIF < 5). Növin impact absorbers reduced braking distance by 1.73 meters at 100 km/h and 1.38 meters at 60 km/h compared to standard suspensions, exceeding initial expectations by 176% and 248%, respectively. The developed statistical model is an effective tool for predicting the effects of speed and braking on braking distance, highlighting its impact on road safety and the automotive industry. These findings underscore the importance of adhering to international standards to ensure data reliability in vehicle testing.
