| Abstract: | Solid Works software and ADAMS simulation software were used to build the virtual prototype and simulate the dynam-ics of the auxiliary operation arm module of modular seedling tending machine.The fact of the application of software to es-tablish 3-D model and dynamic simulation, to verify the auxiliary operation arm module turning, lifting, recovery process showed that the virtual prototype was running well.With ADAMS software, the dynamic simulation of the auxiliary opera-tion arm module was carried out under positive load and partial load, respectively, and obtained stress curve of lift cylinder and turning cylinder in different working conditions, and the stress curve of the key hinge point in different working condi-tions;the force change coincided with the actual force condition of the auxiliary operation arm module.The virtual proto-type technology was used to perform dynamic simulation of the auxiliary manipulator of the tending machine with the char-acteristics of high efficiency, low cost, visual output, and good simulation effect. |
