英文摘要: The trafficability of oilfield special vehicles in beach shallow is the bottleneck of restricting oil and gas resources development.The project intends to establish the soil parameters → grip force→driving force perfect logical model with the wheel force transducer and nonlinear regression modeling methods, to provide technical support for the beach shallow water oilfield special vehicles development. The main contents include: 1) Design of indoor and outdoor test program and confidence level assessment; 2) the principle optimization of the wheel force transducer elastomer and research of nonlinear decoupling method with the structure and software technique; 3) Building the soil - grip force model with the support vector regression method based on domain knowledge and the identification and stability analysis of the model; 4) Construct the trafficability evaluation system with the soil - grip force model and considering the vehicle configuration and driving conditions. The research on soil - grip force model will provide science and quantitative methodologies for the vehicle trafficabilty on shallow water beach estimating.
