固定-固定型弹簧质点系统的能量约束问题

The Problem of a Fixed-Fixed Mass-Spring System under Energy Restriction

基于子系统物理参数和系统惯性能量约束讨论了固定-固定型无阻尼弹簧质点系统的构造问题,通过求解一类广义逆特征问题获得了弹簧刚度和质点质量的计算表达式,并给出了算例.

This paper discussed the structure design of a fixed-fixed undamped mass-spring system under the constraint from energy restriction and prescribed data. The prescribed data involved the physical parameters of subsystem and partial information of modes. By solving a general inverse eigen-problem, the expression of the stiffness and mass has been derived. The numerical example was also given.
