The invention relates to a design method for a front landing gear of a full-maneuverable mechanical model. The design method comprises the following steps: I, acquiring a design size of the front landing gear of the full-maneuverable mechanical model according to the size of a real front landing gear and a predetermined shrink ratio; II, acquiring a force transfer structure of the front landing gear of the model according to a force transfer structure of the real front landing gear, and calculating the mechanical property of the force transfer structure of the simplified front landing gear in a simulation way; III, performing fitting according to the performance parameters of a hydraulic buffer and a tire in the real front landing gear to obtain a spring rigidity coefficient and a tire performance parameter in the simplified structure of the front landing gear; IV, recalculating the spring size and the tire size according to the mechanical property obtained in the step II and the spring rigidity coefficient and the tire performance parameter obtained in the step III; V, performing iterative optimization to obtain an optimal size of the front landing gear of the full-maneuverable mechanical model. Adopting the design method for the front landing gear of the full-maneuverable mechanical model ensures completely that the force transfer structure and the force transfer characteristic can meet the dynamic test requirement.
