本文介绍了一个概念，减振技术的潜力，以减少地面振动的振幅，通过施加一个额外的振动源。通过冲击载荷的情况下提出的想法。基于有限元法，建立了具有吸收边界条件的横观各向同性地基模型的运动方程，并利用FlexPDE软件进行了数值积分。的解决方案的效率进行了分析，在减少地面振动的垂直和水平分量。以无量纲振幅降低因子的形式给出了发电机四个不同位置和不同土壤条件下的结果。在每一个分析的情况下，在一个三层楼的建筑物的振动缓解效果。
This paper describes a concept for vibration-mitigation techniques with the potential to reduce the ground vibration amplitudes by applying an additional vibration source. The idea is presented through the case of an impact load. Equations of motion for the transversally isotropic ground model with absorbing boundary conditions are presented and numerically integrated using FlexPDE software, based on the finite element method. The efficiency of the solution is analysed in terms of reducing the vertical and horizontal components of ground surface vibrations. Results in the form of a dimensionless amplitude reduction factor are presented for four different locations of a generator and different soil conditions. In each analysed case the vibration mitigation effect in a three-story building was achieved.
