The Mathematical Model

The grounding pressure of tracked vehicles is closely related to the overall structure of the vehicles and the ground conditions, and its distribution is more complex and changes in the different center of gravity. So in this paper, under certain assumptions, we derive the mathematical model of the grounding pressure distribution through analysis and research, which can predict the ground pressure distribution of tracked vehicles at any moment. By analyzing the tracked grounding pressure distribution, we put forward the concept of core region of track connecting with the ground, and some meaningful conclusions and formulas for the overall design of tracked vehicles.

Pressure Characteristics

Air-pressure characteristics of air supported fixed floating structures are described in this paper. The theoretical prediction method of responses of the aircushion type floating structure in waves has been proposed. The adiabatic compression is assumed to the prediction method. In this study, model experiments using two aircushion type models are carried out in the wave tank. Then, pressures in the aircushion and the wave exciting force of heave are measured. It is verified to assume spatially uniformly distribution to pressure distribution from explorations by using the experimental results of the pressure and the phase difference. In addition, effects of the initial pressure of the aircushion and the draft of the skirt bounding the aircushion and/or water are little.

Basic Features

In the past decade, a computer aided method for design evaluation of high-speed tracked vehicles with flexible tracks (or tracks with relatively short track pitch commonly in use in tracked transport vehicles and military vehicles) has been developed. It has been successfully used in assisting vehicle manufacturers in the development of new products and governmental agencies in the selection of vehicle candidates. For low-speed tracked vehicles commonly in use in agriculture, construction and logging, rigid tracks with relatively long track pitch are employed to achieve a more uniform ground pressure distribution. To assist manufacturers of this type of vehicle to expedite the development of new products in a cost effective manner, a computer aided method for design evaluation of tracked vehicles with rigid links has recently been developed. It treats the track as a system of interconnected rigid links and takes into account the characteristics of the interaction between track links and deformable terrain. The basic features of the method have been verified by field test data. The method can be an extremely useful tool for the engineer to optimize vehicle design and for the procurement manager to select appropriate vehicle candidates to meet specific operating requirements.
