Beginning with calculation method of the single bow spring stiffness,the test data by means of mathematical statistics is analyzed,and the relationship between the single spring stiff-ness and the combined spring stiffness find out.Finally a conclusion of the calculation method of composite bow spring stiffness was made.And this method is used to calculate the design value of each combined spring stiffness,comparing the design values with the measured value,find that the deviation between design calculated value and measured value is -2.9%~9.3%,the average de-viation is 0.5% and the design value is close to the measured values,which shows that this meth-od has high reliability,good practical engineering value.
