硬质聚氨酯泡沫塑料在压力负荷下能显著的吸收能量,这种硬质泡沫已被制成圆筒形结构装在外柱管内,应用到汽车转向器上。新型结构的转向器柱管具有良好的吸收冲击的能力,完全满足美国FMVSS203汽车安全标准所提出的要求。
Rigid polyurethane foam absorbs energy significantly under pressure load. This rigid foam has been made into a cylindrical structure mounted on the outer column and applied to the steering of a car. The new structure of the steering column tube has a good ability to absorb the impact, fully meet the United States FMVSS203 car safety standards made by the requirements.
