CAE support for vehicle development |
|
|
| CAE realizes virtual engineering environment, and is one of the most important capabilities of V-ENS for enhancing design and engineering process. |
| The effectiveness of well-established CAE procedures and standards of V-ENS have been approved after having been successfully applied in various vehicle development programs. With the utilization of mass storage high-speed supercomputer for CAE, the analysis of vehicle frontal crash can be done within a day which originally requires a lot of calculation time, and contributes to the reduction of the vehicle development period. |
| To systematically perform the entire engineering, including Crashworthiness, NVH, Ride & Handling, Strength & Durability, CFD, Formability, DMU, etc., various solution packages, such as LS-DYNA, NASTRAN, MARC, ADAMS, STAR-CD, VIS-MOCKUP, etc., and pre- and post-processing software of HYPERMESH, ANSA, etc. are used. |

Crashworthiness and Safety Analysis |
|
|
| Supporting the simulation relevant to Crashworthiness and Safety is the most important in the entire vehicle development stages from the concept development of platform to the final manufacturing. CAE technology leads the structural development that perfectly meets various regulations and requirements. From this perspective, V-ENS is thoroughly prepared. Its outstanding manpower, and hardware and software infrastructure enable all the above. |

CFD Analysis |
|
|
|
|
| Exterior aerodynamic analysis is performed to reduce drag coefficient- one of the most important factors in aerodynamics and in improving fuel efficiency- from the stage of style development. Moreover, systems are developed through CFD analysis on HVAC system for the improvement of passenger comfortability, and on engine room cooling and thermal analysis.

NVH Analysis |
|
|
|
|
| The development target is set by dynamic analysis for body and chassis systems which are transmission paths of vehicle noise and vibration, and analysis of the excitation force from engine and road surface. In the design stage, vehicle noise and vibration are predicted through forced response analysis and structure-borne noise analysis on the excitation force from engine and road. Sensitivity analysis and optimization method are applied to bring forth ideas for effective design improvement to enhance noise and vibration performance. |

Ride & Handling Analysis |
|
|
|
|
| As the first stage of chassis engineering work, Kinematics and Compliance data are generated by using commercial and in-house software to decide on the initial hard point. In addition, chassis system is developed to improve dynamic behavior of vehicles by carrying out engine mounting system analysis, Tip-in/out behavior analysis, load data generation for durability, and Ride and Handling simulation for vehicles. |

Durability Analysis
|
|
|
|
|
| Chassis components and system, and body structure should be designed safely in terms of structure, according to various vehicle operation conditions. Load conditions are specified according to various road and operation conditions, strength analysis is carried out, and durability characteristics of vehicles are evaluated. Recently, virtual testing method is applied for vehicle development, in which road load data measured from proving ground, or actual road condition are used directly in the analysis model.
