spring-mass system%inverse problem in vibration%inverse eigenvalue problem%Jacobi matrix%natural frequency
The tridiagonal coefficient matrix for the "fixed-fixed" spring-mass system was obtained by changing spring length.And then a new algorithm of the inverse problem was designed to construct the masses and the spring constants from the natural frequencies of the "fixed-fixed" and "fixed-free" spring-mass systems. An example was given to illustrate the results.
