摘要
为了降低燃油消耗和污染排放,汽车零部件开始选用轻质高强的复合材料替代钢材。板簧是汽车悬架系统的关键性零部件,也是汽车减重的重要组成部分。相对于钢板弹簧,复合材料板簧在至少减重50%的同时还具有更高的疲劳寿命、更佳的阻尼效果以及更良好的耐腐蚀性等性能。介绍了复合材料板簧在国内外的应用和研究现状,分析了复合材料板簧的主要成型工艺及性能特点,并对今后的发展方向进行了思考:应从复合材料板簧的目标应用角度出发,建立从原材料制备、结构设计、工艺优化、自动化生产及性能检测为一体复合材料板簧生产流程,只有生产出兼具高性能和低成本的复合材料板簧才能推动其在汽车行业更普遍的应用。
To reduce fuel consumption and pollution emissions, auto parts begin to select lightweight and high-strength composite materials to replace steel. The leaf spring is a key component of automobile suspension system, and an important part of weight reduction of vehicles. Compared with steel leaf springs, composite leaf springs not only can reduce the weight by 50%, but also have higher fatigue life, better damping effect, and better corrosion resistance, etc. This paper presents an overview of the application and research status of composite leaf springs, analyzes the main forming process and properties of composite leaf springs and reflects on the future development trend: we should set up a production process of composite leaf springs that integrate raw material preparation, structure design, process optimization, automatic production and performance test into one, from the target application of composite leaf springs. Only by producing composite leaf springs with both high performance and low cost can they have more widespread use in the automobile industry.
