Body Engineering

Body Engineering R&D can be divided into two stages: design and development
  • Body Design
  • Body Development

Body design played a very prominent role in HAITEC’s engineering. The body panels (including the Body In White and doors), exterior trims and interior finishing (including trims and seats) are all in the perimeter of body engineering. The stakeholder must be outstanding in organization, communication, aesthetics and attention to details.

Body Design

The body engineering process includes styling feasibility studies in the concept stage, QCD (quality cost delivery) analyses for decision matrixes, typical section analysis, structure reviews, engineering plan drawing design review, 3D model design reviews and Design feedback based on design reviews. And parts level, system level and vehicle level design verification plan to meet the specified targets; Cross-functions communications are also conducted among engineering units and clients to ensure the products meet consumer demands and quality targets.

Body Part Design

A. Body and door parts design

Structural strength, durability, NVH, driving safety, pedestrian protection and NCAP requirements and mechanical smoothness were all taken into considerations during the design process. Body and door parts are all designed in-house by HAITEC through detailed engineering analysis and verification to ensure superior quality.


B. Exterior styling design

Exterior lamp system always being emphasizes on the compromise in between minor details and related regulations requirements. Another key is the bumper design that meets pedestrian protection and low-speed impact.


C. Interior and seats design

Great attention to details is needed to provide drivers and passengers with a comfortable space; and the restraint system for passengers to have afive-star safety vehicle as well.

Thanks to its in-house database and the digital CATIA tools, HAITEC’s core design capability has been strengthened significantly. The database contains past design verification results and body design experience from the past thirty years, while the CATIA tools provide a virtual space to support body design tasks such as ergonomics analyses, cross-section analyses, engineering requirements and package planning.

The body development process involves prototyping and volume production activities for body parts such as paneling, rubber/plastic parts and special components to facilitate the introduction of future models.

In addition to quality, cost and schedule management, body development also involves new materials and techniques. Injection molding of interior parts (see Fig. 1) as well as quality improvements for surface treatment techniques such as curved surface printing, coating, framing and electro-plating are also taken into account. Computer modeling is also used for analyzing the mold flow of panel forming, large plastic components and electro-mechanical integration during the initial design and development phases.

During the prototyping stage, techniques and technologies are tested in order to develop parts that meet quality requirements, reduce costs and shorten the time needed for developing new vehicles. On the new prototypes, new techniques are tested in experiments and the results are accumulated for more experience and better prototyping capabilities.

During the volume production stage, the focus was on part quality and verifying suppliers' volume production capability. Production management techniques were also applied to produce a high quality product.
