    *Crank Web Bending

  • Original language description

    *Optimization of crankshaft mass using Design Assistance System (DASY) software is possible if modifying crankshaft design is carried out in order to obtain minimal possible mass while keeping stresses at acceptable level. Response surface creation basedon ABAQUS/Python parametric FEM model is represented by the current software. Engine-design decisive crankshaft dimensions are not changed to allow usage of optimized crankshaft in the engine where original crankshaft was used. Parametric models are changed using script written in Python language. Optimization process is done and supervised by DASY using regression model according to Crank Web Bending results. DASY is used to define optimization parameters and targets, to automate model modification and solution, and to run the optimization process. Due to the limitations in the computational power, simplified model Crank Stress can be initially optimized. - WP01R2
