In this research, we tried to construct a technology that can efficiently create a model for thermal fluid analysis based on the mesh used for structural analysis. In this paper, we introduce the constructed technology and report on the accuracy of the analysis and the reduction of the analysis lead time when the constructed technology is applied to a temperature prediction analysis of motorcycle exhaust system that takes into account the internal gas flow.

The Development of The Testing Method by the Connection between Driving Simulator and Powertrain Test Bench for Multi-function Synchronous Vehicle Development

We've developed the testing method to realize the synchronous development of the vehicle functions for steering stability, drivability, fuel consumption, noise harshness (NVH) by the connection between a driving simulator and a powertrain test bench. By replacing the actual powertrain and ECU from the part of the model for the driving simulator as a high accurate model, the simultaneous evaluation can be achieved to calibrate both the driver's sensation with the driving simulator and the driving control with the powertrain test bench.

Introduction of Agile Development Technique using New Segmented Mock-up Model with Aerodynamic Noise as Example

Takahiro Nakajima (Honda Motor)･Takuya Iso (Auto Technic Japan)･Sanu Kimu (Persol Cross Technology)

In automotive development, parts such as A-PLR and door mirrors need to balance design and performance, and it is necessary to quickly provide performance insights into the design.
To address this issue, the authors carried out agile development by making part of the car body mock split into pieces, allowing for recombination with parts created using stereolithography.
In this lecture, we will introduce this development method.

The use of test robots is increasing in automobile tests using chassis dynamometer such as driving tests of electric vehicles. Automotive test robots on the market are known to have problems such as inconvenience in use, installation time, and calibration time due to changes in vehicle type. This study conducted research to develop an automobile test robot with improved ease of use. In order to develop a test robot with pedal movements similar to human driving movements, a pedal robot capable of manipulating the brake pedal and accelerator pedal with a three-degree-of-freedom structure was developed and its performance was evaluated.
