This paper describes numerical simulation and analysis of interaction between the parts of rack-and-pinion lock under operational external load, so as to develop design criteria and recommendations for its joints, as well as for more accurate determination of clearances between coamings and hatch covers, required to develop water-tight rubber sealings. These tasks are accomplished by means of detailed three-dimensional finite-element models representing two variants of rack-and-pinion lock, with their further verification. The study included numerical simulation of contact interaction between the parts of the lock, as well as analysis of design solutions for its main joints. As a result, coaming-cover clearances have been determined and manufacturing requirements to rubber sealings of the lock variants under investigation have been successfully formulated.
