Abstract A parametric feature-based modeling was used to model the parts of a combine harvester. The digital virtual prototyping of the harvester was completed by virtual assembly. The finite element analysis of the vehicle frame was made and the result satisfied the requirements. The vibration sieve, which is a key part of the combine harvester, was simulated and optimized. The excellent parameters of the vibration were gained by optimization. The grain passed through the sieve easily after the optimization and reduced the loss rate and impurity rate in theory.
