[ Objective] To design a electric micro-farming machine which is proper for the operating mode and tunetional requirements. [ Meth- od ] ANSYS software was used to conduct finite-element analysis. According to proper structure size and actual working condition, three-dimen- sional model was established. Through force analysis and frame finite-element analysis, working capacity and structure parameters were deter- mined. The machine entity was nmnufactured and relevant verification was conducted. [ Result] Through finite-element analysis, effective data for the machine frame was obtained. According to optimal design parameters, machine entily was manufactured. After verification, new designed machine slructure coud satisfy various operating demands. [Conclusion] The study can provide a theoretical basis fur optimal design of electric micro-farming machines lrame based on the in-wheel motor.
