| Abstract: | Based on the finite element method,the static intensity of the straight plate brake beam for 209-type passenger car is analyzed.Making use of the conventional fatigue design method,the fatigue life of the brake beam is estimated.And using full-size pieces of physical samples,the experimental confirmation is carried.The calculation results are basically consistent with the experimental results.The static strength and the fatigue strength of 209-type brake beam are used to meet the relevant requirements. |
