Abstract EN
Based on the summary of existing pounding force analytical models, an updated pounding force analysis method is proposed by introducing viscoelastic constitutive model and contact mechanics method.
Traditional Kelvin viscoelastic pounding force model can be expanded to 3-parameter linear viscoelastic model by separating classic pounding model parameters into geometry parameters and viscoelastic material parameters.
Two existing pounding examples, the poundings of steel-to-steel and concrete-to-concrete, are recalculated by utilizing the proposed method.
Afterwards, the calculation results are compared with other pounding force models.
The results show certain accuracy in proposed model.
The relative normalized errors of steel-to-steel and concrete-to-concrete experiments are 19.8% and 12.5%, respectively.
Furthermore, a steel-to-polymer pounding example is calculated, and the application of the proposed method in vibration control analysis for pounding tuned mass damper (TMD) is simulated consequently.
However, due to insufficient experiment details, the proposed model can only give a rough trend for both single pounding process and vibration control process.
Regardless of the cheerful prospect, the study in this paper is only the first step of pounding force calculation.
It still needs a more careful assessment of the model performance, especially in the presence of inelastic response.
