| Abstract: | By using histogram analysis and combined with Weibull statistical analysis, the distribution rule of three pointbending breaking load of TU5GP4 model chilled cast iron camshafts was analyzed. The results were as follows： a） the distribution histogram of three point bending breaking load of TU5GP4 model chilled cast iron was of the skewed type, and itsstandard deviation s= 0.223, indicating that the data distribution has high concentrating degree and low scattering degree; b）Weibull modulus was of 33.4 indicating concentrating degree of three points bending breaking load of the camshaft is high, i.e. the reliability of its production process is high. |
