Contact model of the soft-solid interactions plays an important role for robotic and mechatronic systems design. We present a new model of the soft-solid contact that integrates the LuGre dynamic friction model with the beam network model. The LuGre dynamic friction model uses the bristle deformation to capture the friction characteristics and dynamics while the beam network model represents the elastic contact interactions. The new model is applied to a fingertip-like stick-slip interaction application. We present the model prediction and validation results with the experiments. The comparison results demonstrate the effectiveness of the modeling development.
