摘要
针对移动连体式和移动分体式垃圾压缩站的典型举升机构,A、B型举升机构,分别以其液压缸的驱动载荷和驱动功率为研究对象,以其最大值的最小化为目标函数进行机构动力学优化设计。研究结果表明,以举升机构的液压缸驱动功率最大值的最小化为目标的优化设计,可使A型举升机构的最大驱动载荷和最大驱动功率分别降低47.9%和15.3%,而B型举升机构的最大驱动载荷和最大驱动功率分别降低25.5%和8.34%。总体上均优于以举升机构液压缸驱动载荷最大值的最小化为目标的优化结果。意味着,在垃圾压缩站的举升机构设计过程中,以驱动功率为目标的优化设计方法更有成效。
In this paper, the dynamic optimal design of two typical lifting mechanisms of mobile garbage compression stations, named A-type and B-type lifting mechanisms, are conducted based on minimizing the maximum values of the motive force and driving power of the hydraulic cylinder. Results show that the maximum values of the motive force and driving power of the A-type lifting mechanism reduced by 47.9% and 15.3%, respectively, according with the optimization method of driving power, meanwhile, those of the B-type lifting mechanism decreased by 25.5% and 8.34%. Compared with the optimization method based on the motive force, the optimization method based on the driving power can reach a superior result for the dynamic optimal design of the lifting mechanism of the mobile garbage compression station.
