Simulating a drive cycle can have many benefits. Several hot topics right now include improving fuel economy and emissions measures, but there's another way simulating a drive cycle can help you optimize a new vehicle design. A drive cycle simulation can help you predict transient thermal behavior and maximize the capabilities of powertrain and exhaust components. To do this, you need to simulate the thermal activity of these components over a drive cycle—which isn't easy to do....
A Brief Overview of Exhaust Simulation A proper model of your exhaust system provides a critical boundary condition for your underhood/underbody thermal management. Many different simulation methods are chosen today based on the level of fidelity that is required and the boundary conditions that are available. There are four widely recognized methods for simulating exhaust systems....
Packaging constrictions in new vehicles dominate the positioning and organization of components within the engine compartment. With less space and more temperature sensitive components, (plastics for lightweighting, infotainment, and electrical components) thermal management becomes an increasingly critical aspect of vehicle design. Component hot spots can lead to safety, durability, and warranty issues. Careful consideration of component placement and heat shields is mandatory to avoid costly late-stage fixes....
As an automotive designer, cabin comfort is the foundation of customer satisfaction and ultimately, product sales. The rising tide of battery-powered electric vehicles brought a new design challenge to automakers, pushing them to find a way to optimize the sub-systems in the vehicle while avoiding enormous draws on battery power at the same time. This problem is addressed by running transient human thermal and battery tests to optimize for HVAC and battery systems. In this blog, we will understand how an automated coupling process can provide an optimized solution while avoiding the long solve times of highly transient problems. ...
Coupling a thermal modeling tool with your CFD code can provide accurate simulation results, giving you beneficial thermal feedback for your project. Over the past few years, the most effective process to implement these results has moved from writing custom scripts to coupling using an automated coupling program as the methods have become more robust. ...
