地质灾害应急抢险钻机的履带行走仿真

中国地质科学院探矿工艺研究所研制的地质灾害应急抢险快速成孔钻机的设计阶段采用虚拟样机技术:运用三维CAD软件Solidworks设计该钻机的机体三维数字模型;利用RecurDyn多体动力学仿真软件建立该钻机履带行走装置的虚拟样机模型;在RecurDyn环境中整合组装整机并对钻机履带行走进行动力学仿真,分析钻机的行走能力,论证所设计的钻机在进行抗滑桩、边坡加固、钻掘生命通道等地质灾害防治施工工况时的行走稳定性。达到缩短履带钻机研发周期、减少该产品开发成本的目的。

Dynamic Simulation of Tracked Vehicle Using the DADS Software

The track model used in the dynamic analysis and design system software is investigated. A home made tank is taken as an example to illustrate the method for modeling an integral tracked vehicle and perform the dynamic simulation. The obtained results have demonstrated that the simulation method has the advantage of high efficiency, more convenience and more insight into the dynamical behavior of the system.
