摘要
从单片弓形弹簧刚度的计算方法入手,运用数理统计学方法分析试验数据,找出单片弹簧刚度与组合弹簧刚度之间的关系,得出了组合弓形弹簧刚度的计算方法.用该方法得出每种组合弹簧刚度的计算值,将计算值与实测值进行对比,发现本方法得到的计算值与实测值偏差为-2.9%～9.3%,平均偏差为0.5%.计算值接近实测值,说明本方法可靠性较高,具有较好的工程实用价值.
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.
