摘要
建立拆楼机械臂的模型,确定机械臂的危险工况,并针对此工况进行静力学分析。根据分析结果,以轻量化为目标对机械臂进行拓扑优化;基于拓扑优化结果,结合实际制造工艺,对机械臂结构进行优化。优化结果表明:机械臂的质量减少了31.9%;与此同时,机械臂的强度刚度均满足要求,为拆楼机的研发提供了参考。
The model of the mechanical arm for demolition was established,and the dangerous working condition of the robot arm was determined,and statics analysis was conducted for this condition.According to the analysis results,the machine arm was topologically optimized with the aim of light weight.Based on the results of topology optimization,combining with actual manufacturing technology,the structure of the mechanical arm was optimized.The optimization results indicate that the mass of the mechanical arm is reduced by 31.9%.At the same time,both the intensity and rigidity of the mechanical arm meet the requirements.It provides reference for the research and development of the machine for demolishing buildings.
