【Abstract】 On the basis of the overall scheme design, the problems of the forces beared by the pushing pulling mechanism of an air cushion platform vehicle were discussed in this paper. Under given hypothetical conditions, mathematical models describing the relationships between working load and technical specifications of a vehicle were established. According to the design criterion, the equilibrium conditions coordinating the mechanistic system of the pushing pulling mechanism were given in order to find the definite solution. The formulas for three typical cases were derived and the design and calculation of the pushing pulling air cushion vehicle model, as an example, was introduced.更多还原
