通过VB控制SolidWorks中液压挖掘机各液压缸长度参数,实现液压挖掘机姿态的参数化控制,并对模型的建立、系统的设定以及关键技术进行阐述。通过参数化姿态控制系统,在SolidWorks中自动装配出用户指定姿态的液压挖掘机几何模型,用户可以将该几何模型导入有限元软件Ansys中进行有限元分析,解决了有限元分析时挖掘机姿态难以调节的问题。
Through the control of the hydraulic cylinder length parameters of hydraulic excavator in SolidWorks by VB, the parametric control of the hydraulic excavator attitude is realized. The establishment of the model, the setting of the system and the key technologies are also described. Through the parametric attitude control system, the geometry model of the hydraulic excavator with user-specified attitude is automatically assembled in SolidWorks, and the user can import the geometric model into the finite element software Ansys for finite element analysis to solve the problem that the excavator is difficult to handle in finite element analysis Adjustment problem.
