Recently, customer's requirements for dimensional performance become more complex. Automakers are trying to introduce virtual engineering to meet time-to-market thorough validate their design as early as possible to meet market requirements. In the same way, automakers are performing simulation for not only vehicle performance but also vehicle appearance. This study addresses tolerance optimization method for DTS(Dimensional Technical Specifications) which is including typical sections with gap and flush targets using 3 DCS commercial software equipped with GM's in-house program called OPTOLS.

This paper presents enhanced virtual design review process to improve virtual engineering performance and reduce potential risk in physical build. To understand what we did not conduct virtual load case and what we need to improve, thousands of physical issues were analyzed by categories such as virtual available area or not, development phase, and etc. The proposed virtual design review is to integrate alternatives concerning potential risks based on expert’s experience, lessons learned from existing problem-solving database. About 28% potential issues could be reduced though enhanced virtual design review process.

This paper presents how to optimize engine room dynamic clearance. Current issue of engine room dynamic clearance is on the inaccuracy of the specification. The specification of dynamic clearance is set considering the maximum margin of part deformation and variation. The range of dynamic clearance specification is optimized by integrated variation analysis result. For realizing and verifying this method, commercial soft ware 3DCS is used for constructing variation simulation model with tolerance and assembly process.

This paper presents virtual build process to support product launch and the analysis result of virtual build effect in PPV (Production & Process Validation) build. Virtual build is one of virtual engineering process and the purpose is reducing potential physical issues with 3D math data, BOM and build sequence. Using virtual build processes such as BOM contents validation, BOM to VAS comparison and build sequence validation, potential physical issues caused by product engineering and manufacturing engineering can be reviewed at the same time. Through virtual build support, total physical issue and physical issues can be protected using virtual engineering was reduced significantly.
DFFA(Dimensional Fit, Function, Appearance)의 기하공차 해석

This paper presents a process of optimizing GD&T(Geometric Dimensioning and Tolerancing) to allocate tolerances for DFFA(Dimensional Fit, Function, Appearance). The Variation Simulation Model using 3DCS is developed to define the sensitivity of each tolerance input, and a Linear Programming Model is introduced to optimize geometric dimensioning & tolerancing. For verfication of the process, front-end area of vehicle is analyzed and improved 29.3% variation for DFFA requirement.
