摘　　要：为提高拉臂式垃圾车工作装置的整体性能,利用机械系统动力学软件ADAMS,对工作装置中各主要设计点进行参数化,建立工作装置机械子系统、液压子系统模型。在ADAMS环境中利用参数关联技术,将两个子系统模型集成,建立拉臂式垃圾车工作装置液压与机械一体化的虚拟样机模型。采用OPTDES非线性二次规划计算方法,以工作装置液压缸作用力最小为优化目标,对机构中各铰接点位置进行优化计算。优化结果表明,工作装置在装箱和卸料过程所需的液压油缸最大作用力显著降低,装箱时拉臂钩作用力也相应减少。与传统设计方法相比,采用虚拟样机优化设计方法,可提高拉臂式垃圾车工作装置的整体性能,降低制造成本。The main design points of the hooklift were parameterized and its mechanical system and the hydrostatic system were built using the mechanical system dynamics software of ADAMS for the improved performance. The hydrostatic-mechanical virtual prototype was established by the integration of the two systems through parameter correlation technology under ADAMS environment. The locations of revolute joints were optimized with the minimum of the maximal cylinder forces as the optimization goal, by using the non-linear sequential quadratic programming method of OPTDES. The optimization results showed that the maximal cylinder forces had reduced greatly as well as the maximal hook forces, in the container-loading case and garbage-dumping case. By contrast with traditional optimization methods, the introduction of the virtual prototype technology had sharply improved the capability and reduced the cost of the hooklift working device.
