摘要：Manufacturing and machining property are the most important features of structures. The product with good processing property is not only to decrease its costs but also to increase its efficiency. It is very difficult to design and machine because of the complicated results of topology optimization. This study introduces a heuristic approach using an engi?neering constraint in topology optimization sensitivity process. With this special method, the result of topology optimi?zation can meet the structural design requirement. Several numerical examples were provided to show that the positive influence of new engineering constraint method on the reasonable results of topology optimization was significant. It was a good way to control the material distribution of continuum structural topology optimization using this method.
