The design of the dry-dock falling gate"s structure is researched, and integrates the disquisitions and analysis on the dynamic characteristics about dock gate, in order to make the cabin design more visualizing.(2) The emphasis of this paper is the influence of the water hole and gas hole in the tidal cabin and the influence of the drain of the air-operated cabin.(3) In this paper, the building method of the dry-dock falling gate"s parametric model is studied and the dynamic analysis is accomplished in ADAMS, furthermore, the rising-and-falling angle curve is drawn while the dry dock gate is rising and falling.(4) The paper is based on the apprehension of the past theories and researches about air-operated dry-dock falling gate, and is explicated by hydraulic rationales and rising-and-falling mechanical principles. This software is developed by inner programming language in ADAMS and VC. This design could shorten design cycle.
