Abstract

Atypical but real practical problems relating to the dynamics of block-type foundations for machines are considered using the deterministic approach and assuming that the determined parameters are random variables. A foundation model in the form of an undeformable solid on which another undeformable solid modelling a machine is mounted via viscoelastic constraints was adopted. The dynamic load was defined by a harmonically varying signal and by a series of short duration signals. The vibration of the system was investigated for the case when stratified ground (groundwater) occurred within the side backfill was present. Calculation results illustrating the theoretical analyses are presented.

与机器的块状基础动力学有关的选定问题

采用确定性方法并假设确定的参数为随机变量，考虑了与机器块型基础动力学有关的非典型但实际的问题。采用不可变形实体形式的基础模型，通过粘弹性约束将另一个不可变形实体模型安装在其上。动态载荷由一个谐波变化信号和一系列短持续时间信号来定义。研究了侧向回填体存在层状地层(地下水)时系统的振动特性。给出了理论分析的计算结果。
