A method for vehicle–track–soil interaction analysis considering soil deformation

In this work, an engineering practical method is put forward to characterize the static and dynamic mapping relationship between soil deformation and its induced system performance. The main novelty lies in the achievement of mapping relationship analysis subject to arbitrary soil deformation-induced vehicle–track–soil (VTS) static geometric deformation and dynamic behavior. In this practical model, the increment and iteration methods are introduced and integrated into the static mapping analysis to solve the nonlinear interlayered contact and separation, and subsequently, to achieve dynamic mapping analysis under a VTS dynamics framework, besides, the Wavelet transform is applied to obtain the more distinct observation signal in the time domain. Apart from the discussion on the time domain, the analysis on the frequency domain is implemented in the numerical studies to further illustrate the influence of soil additional deformation from the dynamic mapping perspective. Moreover, the difference between the dynamic responses of the unit base plate and longitudinal connected base plate subject to different combination of wavelength and amplitude of soil deformation is analyzed.
