    Abstract: A structural topology optimization design method is provided. A structural topology optimization question is defined to determine at least one set of load and restriction condition and a parameter of lower limit of volume capacity related to a design space model. This model is divided into mesh grids for performing finite element analysis (FEA). Strain energy of each element after FEA is obtained according to the established load and restriction condition and used as a basis for calculating sensitivity of each element. A part of elements is removed or retained according to the degree of sensitivity of each element, and the structural profile and the total volume capacity and total strain energy of residual elements of the structural profile are recorded after each loop was completed. A display interface is used to sequentially show the structural profile and a relationship diagram of structural volume capacity vs structural strain energy.

    Abstract: A method of load characteristic identification and acceleration adjustment for a machine tool is provided. A first acceleration of a transmission system is set according to the weight of a workpiece, and the working platform and the workpiece are driven at the first acceleration. A first elastic deformation of the transmission system and an amount of first position error of the transmission system are calculated when transmission system is moved at the first acceleration. A dynamic error is calculated according to the first elastic deformation and the first position error. When the dynamic error is less than or greater than a target error, a second acceleration is set to the transmission system, and a second elastic deformation and a second position error are calculated when the transmission system moves at the second acceleration unit the dynamic error is converged to the target error.
