摘　　要：根据履带板的结构和载荷特点,开展了轻量化高强度铝合金材料在履带板体上的应用研究.以降低危险截面应力为目标,通过局部结构强化达到了使用要求.样品试制采用半连续铸造和等温模锻相结合的工艺成型方法,保证了履带板的强度.理论计算和试验结果表明:同外形尺寸的铝合金板体经过优化后可以达到与钢制履带板相接近的极限拉力,重量减轻了30%,验证了铝合金材料及其工艺技术在履带板上应用的可行性.According to the structural characteristics of the track shoe,the application of lightweight and high strength aluminum alloy materials on the track shoe is carried out.With the aim of reducing the stress of the risk section,the local structural reinforcement is employed.This aluminum alloy track shoe adopts semi-continuous casting and isothermal die forging.Theoretical calculation and test results show that:the ultimate tensile strength can be reached with the steel track shoe after optimization,and the weight can be reduced by thirty percent.The feasibility of the application of aluminum alloy material and its process technology on the track shoe is verified.
