自卸汽车Y式举升机构优化设计

Optimum Design of Y-type Lifting Mechanism of Dump Trucks

应用优化理论提出了自卸汽车Y式举升机构铰点位置参数的优化设计方法。着重讨论了数学模型的建立及计算辅助设计原理，并以计算实例验证了本方法的先进性与有效性。

Using optimum theory,this paper proposes an optimum design method of Ytype lifting mechanism of dump trucks. The mathematical model and the principle of CAD arediscussed. A practical example shows the correctness and effectiveness of this process.
