在分析了半履带式气垫车垂向受力和行驶阻力的基础上，得出了功率消耗和地面土壤参数的关系，求得了风机最佳转速。在不同土壤条件下，控制风机工作在最佳转速，可使半履带式气垫车功率消耗最小。提出了一种在气垫车行驶过程中测算土壤参数近似值的方法，该近似值经修正后可为功率控制提供土壤信息。
Based on the analysis of vertical force and running resistance of half-track air-cushioned vehicle, the relationship between power consumption and soil parameters is obtained and the optimal speed of fan is obtained. In different soil conditions, the control of fan work at the best speed, the half-track air-cushion car can minimize power consumption. A method of estimating the approximate soil parameters during the driving of the air-cushion vehicle is proposed. The modified approximation can provide soil information for power control.
