NEW STORAGE SYSTEM FOR ENGINE DURING TRANSPORTATION

Abstract

The existing system of protection of a machine group, engines in military vehicles TATRA 815, from corrosion effects is only applicable to vehicles parked indoors; in sea, air, railway and road transportation, individual machine components constituting functional parts of the engine cannot be protected adequately from relative air humidity possibly inducing degradation processes in a material leading to the occurrence of corrosion. In the paper, a scientific method of multicriteria evaluation of variants is employed, using Saaty’s method to determine criteria weights and Metfessel’s method of allocation of 100 points, to make a comparison of the existing method of storage of T3-930-50 type engine and a newly designed system of engine storage that is applicable indoors as well as outdoors, or possibly during transportation. The goal of the research was to provide a qualitative evaluation of the impact of degradation on the life cycle of a military vehicle, and an economic evaluation of a newly designed system of short-term military vehicle storage, applied to TATRA 815 military vehicle, as opposed to the existing storage method.

Key words: Corrosion inhibitor, degradation process, storage, life cycle relative air humidity
