摘　　要：为实现某泵送系统Φ260型号砼活塞轻量化,对其压板和连接杆分别进行优化设计。压板采用ZG45铸造成型代替45圆钢机加工成型,并拓扑优化结构,质量从8.3 kg下降至6.0 kg。连接杆根据受力情况进行合理拆分,受力较小部位采用铝合金替代40Cr实现减轻质量。优化后的砼活塞总质量为20.02 kg,相比优化前减轻质量27.8%,材料安全系数更高,拆装操作性更好,且总成本保持不变。To realize lightweighting of the 260 concrete piston of a pumping system,its pressure plate and connecting rod are optimized and designed respectively.The pressure plate is casted by ZG45 instead of machined by 45 round steel,and a topology optimization structure is used,which reduce the mass from 8.3 kg to 6.0 kg.The connecting rod is reasonably disassembled according to the stress situation,and aluminum alloy is used instead of 40Cr to reduce the mass of the less-stressed parts.The total mass of the optimized concrete piston is 20.02 kg,which is 27.8%less than that before optimization,with higher material safety coefficient,better disassembling and assembling operability and unchanged total cost.
