以图 1所示的铝合金型材部件为例,其横截面积 S=0. 00043m2, 铝 合金 6082T6 的抗拉强度 Rm=31幌 Pa, 可得抗拉力 F=Rm χ S=l 33300 (牛),其 1米长的重量为 G=2. 7g/cm3 χ 430cm3=l . 16 kg。
与现有技术相比, ^ 设钢骨架纵梁为 40 X 50 X 1. 75矩形钢管, 则其 1米长的重量为 2. 378kg ,其到屈服极限时的抗拉力为 F=Rm x S, 其中 Rm是抗拉强度, 单位是 MPa, S为矩形钢管横截面积, 单位是 m2 , 矩形钢管 Q2 35的抗拉强度 Rm是 415MPa , 计算知矩形钢管横截面 积 S=0. 0003 m2, 可得抗拉力 F=Rm x S=124500 (牛) , 因而图 1所示 的铝合金纵梁到屈服极限时的抗拉力高于矩形钢管纵梁,而重量却不 到矩形钢管纵梁的一半。
因此我们可以看出使用本发明的车架部件其在大大减轻重量的 同时, 能够达到现有骨架为矩形钢管结构的客车的强度,使客车的承 载能力提高, 减少能耗, 并且不会生锈, 延长使用寿命。
以上所述仅为本发明的较佳实施例, 并不用以限制本发明, 凡在 本发明的精神和原则之内, 所作的任何修改、 等同替换、 改进等, 均 应包含在本发明的保护范围之内。
