This application relates to a simulation method and system for spring damping characteristics. The simulation method includes: establishing a damper simulation model, the simulation model containing variable preliminary performance parameters of internal components; monitoring and accumulating aging physical quantities of the internal components of the damper during the simulation model's operation; periodically correcting the preliminary performance parameters of the corresponding internal components in the simulation model based on the aging physical quantities, and recording these as corrected performance parameters; predicting the performance of the damper at different aging stages based on the corrected performance parameters, and outputting the state information of the internal components of the damper. This application, by incorporating physical quantities from the actual aging process into the simulation loop and dynamically adjusting the model parameters, provides a more realistic prediction of damper performance, enabling accurate assessment of the damper's performance consistency throughout its entire lifespan from the initial design stage.

This invention discloses a xenogeneic-free culture method for hiPSCs and its quality monitoring method. The xenogeneic-free culture method includes the following steps: hiPSC cells are seeded into the wells of a culture plate coated with VTN-N matrix gel, and cultured for the first stage using E8 complete medium containing 5-15 µM Y-27632. After 20-30 h of culture, the medium is replaced with conventional E8 complete medium without Y-27632 for the second stage of culture, until the cell confluence reaches 60%-80%. This xenogeneic-free culture method ensures efficient cell expansion under conditions with clearly defined chemical composition. This method further optimizes the seeding density and culture period of hiPSCs, controls cell passage at 60%-80% confluence, and significantly reduces the risk of spontaneous differentiation by limiting the maximum culture time and upper limit of confluence.
