某专用车辆架设装置的虚拟优化设计

Virtual Optimization of Erection Device of Certain Special-Purpose Vehicle

为对某专用车辆架设机构结构进行优化设计,依靠虚拟样机技术建立专用车辆架设装置的虚拟仿真模型,对最危险状态下的基本臂和伸缩臂进行结构有限元分析,在满足其强度和刚度的前提下对吊臂的结构进行优化设计,进而降低整个吊臂的质量。经分析,该方法优化了架设机构结构,减轻质量,合理可行,可用于物理样机设计、改进或新产品的开发。

To optimize the erection device of certain special-purpose vehicle,the paper applies virtual prototyping technology to establish a simulation model,and perform finite element analysis(FEA)of basic arm and telescopic arm under the most dangerous operating situation,resulting in optimization of lift arm structure on the premise of meeting strength and rigidity requirements,and reasonable reduction in weight.This method can provide reference for design and modification of physical prototypes or other new products.
