摘　　要：针对某公司开发的一种新型直臂式高空作业车的稳定性问题,对整机进行了稳定性分析和优化设计。首先,运用SolidWorks软件建立了三维模型,经过简化将模型导入ADAMS中,并运用ADAMS软件建立了整车的动力学模型;然后,根据国家标准把作业车稳定性分为水平面上、斜面上和作业稳定性试验3种情况,分别进行了检验,发现该作业车稳定性不符合要求;最后,为了提高稳定性,适当增加了配重,仍有局部失稳的现象存在;利用了有限元分析方法,采用了Abaqus软件对作业车的伸缩臂进行了轻量化设计。研究结果表明:通过适当增加配重质量和对伸缩臂的拓扑优化,伸缩臂体积减少到原来的70%,且伸缩臂的应力和变形在可接受的范围内,地面对4个轮胎的支撑力最小也可达到1300 N;既有效地提高了作业车的稳定性,又降低了生产成本。Aiming at the stability problem of a new type of straight-arm aerial vehicle developed by a company,the stability analysis and optimization design of the whole machine were carried out.First of all,the SolidWorks software was used to establish 3D model,the model was introduced into the ADAMS,and the dynamic model of the whole vehicle was established by using ADAMS software.Then,according to the national standard,the stability of the working vehicle was divided into three conditions:horizontal plane,inclined plane and operation stability test,and it was found that the stability of the working vehicle did not meet the requirements.Finally,in order to improve the stability,the counterweight was appropriately increased,but there was still local instability phenomenon.The finite element analysis method and the Abaqus software were used to design the telescopic arm of the working vehicle.The experiment results show that the volume of the telescopic arm is reduced to 70%,the stress and deformation of the telescopic arm are within an acceptable range,and the ground support to the four tires can reach 1300 N.It does not only improves the stability of the working vehicle,but also reduces the production cost.
