摘　　要：推导出了串联弹簧和并联弹簧的等效劲度系数计算公式,同时从实验的角度利用振动法对串联弹簧和并联弹簧的等效劲度系数计算公式进行了验证。发现实验值与理论计算值的相对误差较小,二者非常吻合,说明串并联弹簧等效劲度系数计算公式是正确的。该研究一方面有助于学生进一步理解串并联弹簧等效劲度系数的概念,另一方面在实际生产和生活应用中也有一定的参考价值。A formula is derived to calculate the equivalent stiffness coefficient about springs connected in series and parallel. At the same time,they are validated in vibration method from the experimental point,the experimental re-sults and theoretical calculation results are very well,It illustrates the formula of calculating the equivalent stiffness coefficient about springs connected in series and parallel is correct. The research results help students to further un-derstand the equivalent stiffness coefficient about springs connected in series and parallel spring,they also have cer-tain reference value in actual production and application.
