Tiivistelmä
The focus of this paper is the modeling, structural analysis and verification of different parallel mechanisms. Static and transient simulation analyses of the representative KOHL and STAR platforms were carried out using ANSYS. By adopting specific grid partitioning strategies and constraint Settings, the simulation accuracy and efficiency have been improved.
The results show that complex structures have better stiffness and accuracy. The maximum static deformation of the KOHL platform is 0.95mm, the maximum transient deformation is 0.5043mm, and the maximum equivalent stresses are 55.69MPa and 68.86MPa respectively, all within the allowable range of S235JR steel. The STAR mechanism has also received similar verification.
Studies have confirmed that combining simulation, modeling and experiments can enhance the reliability of the design. The research results provide practical guidance for the mechanical selection in industries such as manufacturing, medical robots and aerospace applications.
