Applying CAE technology to the medium-speed four-stroke engine development methodology at Niigata
Heavy-Duty-, On- und Off-Highway-Motoren 2016
11. Internationale MTZ-Fachtagung
Referent(in): Toshiyuki Saito, Dr. Satoru Goto
In recent years, applying Computer Aided Engineering (CAE) technologies have become common in
the engine development. Especially in recent engine development, it is necessary to utilize these
technologies for achieving sophisticated design owing to meet enhanced environmental regulation and
keen competition at the market. Niigata Power Systems has developed and manufactured a lot of
diesel engines for marine, power plant and rail car application for long years. Based on these experiences
and applying CAE technologies for engine development, modernly high efficiency engine has
been developed and marketed, namely 28AHX, 17AHX, 28AGS, 28AHX-DF.
Various CAE technologies such as Finite Element Analysis (FEA), Computational Fluid Dynamics
(CFD), and performance simulation have been applied to development term throughout from the concept
design phase till detailed design phase. According to utilize CAE technologies in a development
phase, light-weight and compact design with sufficient strength and stiffness in main components are
achieved from the aspect of structural design. Also combustion calculation and performance simulation
are applying to improvement of engine performance and cooling ability. These CAE technologies
are also applying to another products development in Niigata such as gas turbine and ship propulsion
system, contribute to short development term, improvement of product performance and clarification
physical phenomena. This paper describes examples of applying these CAE technologies in development.
