Optimizing the design of engine actuation systems using system simulation

“Through model-based development with OEM, we [at Denso] contribute to more advanced powertrain development”

Masashi Hayashi – Digital engineering expert for powertrain components design and simulation at Denso Corporation.

 

Developing advanced and innovative powertrain is a complex challenge to meet increasing fuel economy and emission standards. Suppliers and OEM need to work together to accelerate the development of their new vehicle. Interaction and the use of a common methodology such as model-based development adopting a common system simulation platform can be a way to achieve in short lead-time development and innovation targets.

Siemens PLM with Simcenter Amesim enables the collaboration between suppliers and OEM, with IP protection and encryption. The advantage on both sides from model sharing is the reciprocal understanding of challenges and benefits. By joining the on-demand webinar “Optimizing the design of engine actuation systems using system simulation” learn how the supplier Denso and the expert Masashi Hayashi analyze an ICE actuation system performances based on OEM requirements using Simcenter Amesim, and assess the benefits from each side.

Application case:

A robot composed of three arms able to handle small objects at up to 300 movements per minute. This ensures excellent throughput for the manufacturer that requires packaging within industries such as pharmaceuticals or foods … 

How Denso optimize hydraulic Variable Camshaft Timing (VCT) design based on performance specification from OEM?

Masashi Hayashi focuses on the development of hydraulic Variable Camshaft Timing (VCT) using system simulation. The challenge in optimizing hydraulic VCT systems design is to improve engine performance, reduce emissions and increase fuel efficiency compared to engine with fixed camshaft.

There are 2 characteristics to be fulfilled and optimized: the VCT speed and stability, in various working conditions (low/high power generation) – based on OEMs requests. Using Simcenter Amesim, the Simcenter system simulation solution, allows validating the correct VCT architecture to satisfy both phase speed and stability.

The additional target for Denso as an engine actuator supplier is to use existing legacy/core design data in the simulation model for more design reliability. By watching the webinar discover how Denso simulation reaches the results accuracy allowing to confirm their VCT model design, based on OEM requirements.

You are eager to know more about other combustion engine actuation systems that you could optimize using Simcenter Amesim? Francesca Furno, our hydraulics expert shows how system simulation easily helps you to tune and improve fuel systems, valvetrains, engine mechanical systems and airpath and exhaust systems and finally the overall vehicle performance. Go deeper into details by watching the live demonstration about Variable Compression Ratio System optimization with Simcenter Amesim at the end of that webinar.
