四种灰铸铁凸轮轴硬度HB与HRB关系的统计分析

Statistical Analysis of Relationship Between Hardness HB and HRB of Four Kinds

通过统计分析研究了四种灰铸铁凸轮轴硬度HB与HRB之间的关系,获得了四种灰铸铁凸轮轴HB与HRB之间回归方程。研究发现,灰铸铁凸轮轴的基体硬度HB与HRB在试验范围内正相关,并对此做了分析。

The relationship between the base hardness HB and HRB of four kinds of gray cast iron camshafts have been studied by using statistical analysis and the regression equations of the relationship between HB and HRB for four gray cast iron camshafts been obtained, Results have showed a positive correlation in the experimental range with the base hardness between HB and HRB in four kinds of gray cast iron camshafts. A preliminary analysis in the above relations has been made.
