摘要：Poly(dibutyl itaconate-co-isoprene-co-methacrylic acid)(PDIM) elastomer was designed and synthesized by redox emulsion polymerization under mild conditions. PDIM has high molecular weight, relatively high yield, and low glass transition temperature(Tg). The structure of PDIM was determined by FTIR and NMR, and the carboxyl content was obtained by titration in a non-proton solvent. Tensile strength and elongation at break increased with increasing carboxyl content. In addition, the interaction between PDIM and silica was elucidated by rubber process analyzer(RPA) and TEM, and the results showed that the silica-PDIM interaction was strong, but the silica-silica interaction was weak.

摘要：在满足大赛规则^([1])要求的前提下,针对FSAE方程式赛车的整体性能及赛道状况,提出一种较为先进可靠的传动系统的优化设计方案。首先利用MATLAB建立数学模型,对赛车进行动力性能仿真,得到最优主减速比。再利用CATIA建模,ANSYS分析,进行机械结构的优化设计。最后,在实车调试中,针对赛车的实际状况,不断对LSD(限滑差速器)进行调教,使赛车性能达到最优。
