AN APPROACH TO ANALYSIS OF NON LINEAR CHARACTERISTICS OF MARINE ENGINE\u27S SPEED REGULATORS

Marine engine speed regulators have been observed as non-linear dynamics models, those mathematical characteristics are similar to system of differential equations. Theoretical and experimental analysis of such has been done, to comprise behaviours of regulator models. Mathematical approach to equation solutions is determined by well known methods of numeric integration, but approach to Runge-Kutta method was preferred to reach reliable values of unknown system variables. Computer simulation and computer-aided design is the best tool for system modelling representation. Therefore, an acceptable software algorithm has been presented to enable understanding of software simulated analysis, and to get numerical solutions of system equations

SYSTEM DYNAMICS MODELLING AND SIMULATION AS PART OF EDUCATION IN MARINE SCIENCE COLLOQUIUMS

By showing a characteristic theme of an educational unit, which is presented with the aid of a computerised simulation based on a mathematical model, a statement is illustrated claiming that utilisation of computers can shorten the time needed for presenting expert knowledge. At the same time, the quality and the clarity of the lecture is improved. A positive and a favourable boost to the student\u27s creative capabilities should be added

TEČAJEVI - BITNI ELEMENT STALNOG OBRAZOVANJA POMORACA

Na osnovi prikaza tečajeva za stalno obrazovanje pomoraca u svijetu i kod nas te provedene analize, uočene su široke mogućnosti da se poboljšaju postojeći te otvore novi tečajevi na Pomorskom fakultetu, Dubrovnik. Posebno je istaknuta perspektiva da se prošire obrazovni programi opremanjem fakulteta strojarskim simulatorom

KOMPJUTORI U NASTAVI BRODSKIH DIZELSKIH MOTORA

Prikazom karakteristične tematske nastavne jedinice u kojoj je izložena jedna mogućnost uporabe kompjutora u nastavi predmeta "Brodski dizelski motori", ilustrira se tvrdnja: Nastava s kompjutorima omogućuje da se skrati vrijeme potrebno za izlaganje stručnog predmeta; uz povećanje kvalitete učenja i povoljan utjecaj na odgoj kreativnih sposobnosti studenata

SYSTEM DYNAMICS SIMULATION MODEL OF THE MARINE DIESEL ENGINE

Dynamic research of the marine Diesel engine is relatively a big problem, because it is a "complex system" where particular elements and system as a whole should be analysed. In the paper, this problem is elaborated with system dynamics and by forming simulation models: System dynamics mathematical model of marine Diesel engine; System dynamics structural model of marine Diesel engine; System dynamics computer model of marine Diesel engine. Authors suggest using the represented models in education process, and when designing new constructions

JEDAN PRISTUP ANALIZI SILA KOJE DJELUJU NA STAPNI MEHANIZAM DIZELSKIH MOTORA

Analiza sila stapnog mehanizma pri konstrukciji dizelskih motora svakako je od prvorazrednog značenja za uspješno rješavanje cijelog niza elemenata i za kvalitetan rad, kako motora tako i stroja koji motor pogoni. U radu se analiziraju sile koje djeluju na stapni mehanizam s posebnom pozornošću na sile od tlaka plinova i sile inercije. Uporabom kompjutora u analizi moguće je uzeti u obzir utjecaj velikog broja parametara i izbor njihovih optimalnih vrijednosti, što rezultira pouzdanom konstrukcijom, mirnim i dugotrajnim radom motora
