Revolution Fuel-Cell Vehicle（body part）
1. Introduction
1.1 Revolution Fuel-Cell Vehicle profile
In recent years,the rapid development and commercialization of fuel-cell vehicle propulsion swept the whole word,and its energy efficient and zero emission or near-zero emissions,good environmental performance,making the development of hot spots of today's word energy and transport ctors. With rhe active participation of major international car manufacturers and oil giant,from the capital to technology,has invested heavily, fuel cell vehicles have been out of the lab,began commercial journey.Many experts are optimistic that fuel-cell vehicles will lead to a revolution in the automotive industry,and eventually replace the traditional diel locomotive into the mainstream.
The Revolution fuel-cell concept vehicle (Figure1.1)was developed internally by Hypercar
to demonstrate the technicalfeasibility and societal, consumer, and competitive benefits of holistic vehicle design focud on efficiencyand lightweighting. It was designed to have breakthrough fuel economy and emissions, meet U.S. andEuropean Motor Vehicle Safety Standards, and meet a rigorous and complete t of product requirements fora sporty five-pasnger SUV crossover vehicle market gment with technologies that could be in volumeproduction at competitive cost within five years (Figure1.2).

1.2 Revolution Fuel-Cell Vehicle advanced technology
The Revolution combines lightweight, aerodynamic, and electrically and thermally efficient design with a hybridized fuel-cell propulsion system to deliver an unprecedented combination of features:
? Seats five adults with a package similar to the Lexus RX-300 ? 1.95-m3 cargo space with the rear ats folded flat
? 2.38 L/100 km (42 km/L, 99 mpg) using compresd 345-bar gaous hydrogen fuel ? 530-km range on 3.4 kg of hydrogen ? Zero tailpipe emissions
? Accelerates 0�C100 km/h in 8.3 conds ? No damage in impacts up to 10 km/h
? All-wheel drive with digital traction and vehicle stability control
? Ground clearance adjustable from 13�C20 cm through a mi-active suspension that adapts to

? Potential for the sticker price to be competitive with the Lexus RX300, Mercedes M320, and the BMW X5 3.0, with significantly lower lifecycle cost.
How is this achieved? Through careful whole-system design that integrates veral advanced technologies at once in synergistic ways. An overview of some of the technologies in the Revolution can be found in Figure1.3 and background information is available in [1.4, 2.1, 2.2, 2.3].

1.3 Lightweight design
sumo Every system in the Revolution is significantly lighter than conventional systems (Table 1.1 and Figure1.4).Different techniques were ud for each system to achieve such weight savings. The body structure achieved nearly 60% mass reduction versus steel by using a combination of carbon-fiber composites, aluminum, and unreinforced thermoplastic.瘾君子是什么

Carbon-fiber composites were ud in the pasnger safety cell and in dedicated composite energy absorbing members. Aluminum was ud primarily in a front-end sub-frame, and unreinforced composite panels form the vehicle’s skin (Figure 2.1). The aluminum subframe and plastic skin are made with standard production techniques and
will thus not be discusd in detail here.

2. Composite Safety Cell Structural Design
The overarching challenge to using lightweight materials is cost-effectiveness. As carbon fiber composites cost significantly more per kilogram and per unit stiffness than steel, cost savings must be found in the structural design and manufacturing methods in order to make
