The commercial vehicle frame based on the composite material comprises a left longitudinal beam and a right longitudinal beam, and a first cross beam, a second cross beam, a third cross beam, a fourth cross beam and a fifth cross beam are fixedly arranged between the left longitudinal beam and the right longitudinal beam. Reinforcing plates are arranged in the positions, between the first cross beam and the second cross beam, of the left longitudinal beam and the right longitudinal beam, and first supports are installed on the sides, opposite to each other, of the left longitudinal beam and the right longitudinal beam and directly face the front portion of the second cross beam. Compared with the prior art, the weight is obviously reduced, the number of layers, the angle of the layers and the sequence of the layers are elaborately optimized by utilizing the characteristics of high specific strength and high specific modulus of the carbon fibers and the excellent impact absorption capacity of the glass fiber layers, and it is ensured that the frame can show the optimal mechanical property and durability under different working conditions.
本发明公开了一种基于复合材料的商用车车架,包括左纵梁、右纵梁,所述左纵梁与所述右纵梁之间固定设置有第一横梁、第二横梁、第三横梁、第四横梁、第五横梁,所述第一横梁和所述第二横梁之间的所述左纵梁内和所述右纵梁内皆设有加固板,所述左纵梁和所述右纵梁相背的一侧且与所述第二横梁前正对的位置安装有第一支架,通过采用高性能碳纤维和玻璃纤维的多层交替铺设策略,实现了显著的重量减轻,利用碳纤维的高比强度和高比模量特性和玻璃纤维层卓越的冲击吸收能力,对铺层层数、铺层角度以及铺层顺序进行了精心优化,确保了车架在不同工况下均能展现最优的力学性能和耐久性。
