Life Analysis

According to the fatigue and fracture reliability theory, the criterion of piston fatigue crack growth rate da / dN is induced using set-value theory of fatigue and fracture mechanics on the basis of actual safety and life of the marine diesel engine piston. Life analysis and security evaluation of large marine diesel engine piston was implemented with this criterion, which affords an important reference for the application of large marine diesel engine.

Hierarchy Process

Facing to the problem of hierarchical structure decision analysis which is made of scheme level + factor level + target level, the analytic hierarchy process gives a whole set of solution and process. This method is used to evaluate diesel engine simulation model. Evaluate original mean value model of large-scale low-speed marine diesel engine and the new one by this method. Calculated results prove this method is applicable.

Marine Diesel

For matching various working condition of ship propulsion system, a modified mean value model of a large-scale low-speed directly reversible marine diesel engine is put forward. A starting and braking torque module is added to the conventional model. A new friction model which considers static friction is adopted. So, the new model can run smoothly across all propulsion working condition, such as starting, running, braking, reversing, etc. The dynamic simulation models of propeller running across four quadrants and ship longitudinal motion are given too. The 5S60MC marine diesel engine equipped on a 76000DWT bulk carrier is taken as an example. The simulation results show that steady data of diesel are in good accordance with test-bed data, and dynamic data match to ship sea trial data in crash stop condition. The best is to read these instructions and follow the outline of this text.
