Digital Activity

Infiniti JX was NNA’s first V3-P project which is a shortened development schedule, key reductions are:

Enhanced Digital phase activity by CAD data quality and CAE

Physical phase schedule 19.5 month (6.5 month compressed)

JX35 Torsion Targets

JX35 Competitor #3

Rear Torsion requires a higher target to make up for reductions in other systems:

Tire width decrease for fuel economy improvement

Mass reduction


JX35 Torsion Targets

Orange = Secondary

Red = Primary

Several iterations of CAE were

run to fine tune stiffness and

increase mass reduction.

Critical parts for Body

stiffness are:


Design Challenges


Design Challenges

40mm of headroom

improvement

Blue – Pathfinder RR Roof Section

Orange – JX35 Section

Hinge was moved to improve head room

JX35 Design Conventional Design


Design Challenges

Deep clearance pocket was required to eliminate

Styling bump at Hinge area. This reduced section caused

larger stress issues than expected in the digital phase

Design Challenges

Hinge Loading

UPR D-PLR HAS THICKER PARTS AND LESS REINFORCMENTS.

Material Usage BIW

Upper Body Utilization

35% UHSS by mass

Platform

39% UHSS by mass

Material Utilization High strength performance

Roof Crush

Front Crash

Side Impact

UHSS utilization: High strength with reduced weight


Safety – Roof Crush


IMPACT SAFETY (Roof Crush)

The upper body construction minimizes the

intrusion into the occupant compartment

through the application of high strength

steels. - Roof strength achievement with smaller section sizes to

meet visibility and roominess targets.



Baseline Final

UHSS application and optimization:

- 8.8kg mass savings in upper body

- Approx. 20% performance improvement


Safety – Rear Impact


IMPACT SAFETY (Rear Impact)


Safety – Side Impact


<The Merit to Users> Safety Zone Body structure and efficient restraint systems allow for improved Safety

performance.

IMPACT SAFETY (Side Impact)

<Key points for side impact>

<Body Structure> Designed to maintain integrity of the cabin in the event of a side collision by use of

Multi-Load Path impact force dispersion structure and use of high strength steel.

<Restraints> Side airbag

Energy absorption airbags with separate chambers for chest/abdomen and pelvis areas

allows for occupant injury reduction.

Inflatable Curtain

Occupants of all 3 rows are protected by the inflatable curtain airbags.


Side SILL reinforcement for dispersion to front and rear cabin

<Impact Force Dispersive Side Body Structure>

Multi-Load Path Structure



Safety – Front Impact


IMPACT SAFETY (Front Impact)

<Key points for frontal crash>

<Body Structure> Crushable zone

Efficient Energy absorption side member structure was achieved with the use of

high strength steel.

Safety zone

Designed to maintain its integrity in the event of a front collision by use of Multi-

Load Path impact force dispersion and use of high strength steel.

<Restraints> Seatbelts

Pre-tensioner & load limiter are equipped for driver & passenger as Standard.

Front Airbags

SRS airbags are equipped for driver & passenger as Standard.

<The Merit to Users> Body structure crushable zone & safety zone with efficient restraint systems allow

for improved Safety performance.


Front pillar Multi-Load Path for Impact Force Dispersion

Front Side Member

Side Sill

Crushable Zone: Crash energy management zone

designed to absorb the energy

generated upon impact.

Safety Zone: Rigid zone designed to maintain its

integrity with minimal deformation to

protect the occupants and the fuel

tank.
