Aircraft might travel faster, and cars might be more flexible, but neither of these are capable of the mass transportation needs that a robust economy requires.
From freight hauling across the United States to the most advanced bullet trains in Europe and Japan traveling over 200 miles per hour (320 km/h), STAR-CCM+ can handle all your simulation and design needs, such as:
Though aircraft, or even cars are most associated with aerodynamic simulation, it is easy to argue that trains benefit greatly from optimization of drag. Even when considering a slow moving freight train with over one hundred cars, aerodynamic simulations can help, but by far the most important application within the Rail sub-industry is for new bullet trains across the world. With drag being a function of velocity squared, a 200 MPH train needs to be perfectly aerodynamically streamlined to be able to maintain that speed. STAR-CCM+ is well validated to perform all external aerodynamic simulations.
The massive diesel engines used to pull modern day trains are complex machines. Enormously powerful, they produce Megawatts of electricity to power every aspect of the train. STAR-CCM+ is proven in the design of such engines, from the complex pumps and pistons to fuel injection. It can even model the exhaust, allowing designers to better manage the train’s pollutants within stations where hundreds or thousands of people congregate.
The Electric Motors that drive modern trains require enormous power from the engine to turn all of the hundreds of wheels. Losses from the conversion process between the engine, through the converter, and to the wheels is a major concern for all parties involved in the train’s operation, and the most efficient process carries great benefits. CD-adapco provides all the solutions needed for the entire power train,
Trains are loud. Anybody can attest to this fact. Modern advances in Aeroacoustics, lead by STAR-CCM+, can simulate the decibel level from trains as they pass by, whether they are slower freight trains or state of the art bullet trains. Optimate+ by CD-adapco and Red Cedar Technologies will automatically find the optimized design state, such as the lowest noise level, quickly and easily.
Trains have a unique environmental factor to consider, in that as they pass through tunnels, their pressure dynamics alter significantly. Such pressure changes can have adverse effects on moving rail cars. STAR-CCM+ is fully capable of simulation of such pressure dynamics, giving peace of mind.
Not only does a rail car need to be fully analyzed on the outside, but the interior needs equal measure. Passengers need environmental control as does specialized cargo such as livestock, and refrigerated or special temperature goods. STAR-CCM+ is fully validated for all environmental control needs that may be encountered across the full range of imaginable applications.
