... moving on different terrains are carried out, with the digging force of the head and the resistance of the flexible pipe acting on the prototype. A great number of kinetic and dynamic characteristics of the virtual prototype on bumpiness terrain are analyzed in detail. The motion performances...

... in vertical pipelines grains of solids flow mainly in the core of the stream, often an assumption is accepted that flow resistance of a mixture is equal to the flow resistance of homogenous liquid. By these simplifications, a number of authors present following equation for calculation of necessary pressure...

... and the soil properties are essential. For this reason a method is presented to deduct soil mechanical parameters from the actual operation data of the vehicle. A brief introduction of the calculation of the vehicles' traction force and driving resistances is given. Furthermore, an overview is presented about...
