Abstract: The use of a new material is a hopeful strategy for breaking through the barrier of improving the product performance and/or the lowering of the product manufacturing cost. However, if the ...

Abstract: This paper proposes a method for evaluating forced and self-excited vibrations at the design stage of machine-tool structural systems. Cross modal flexibilities between the forced excited and the ...

Abstract: Design sensitivity analysis of frequency response is required to improve and optimize dynamic characteristics of machine-tool and other machine structures. This paper presents design sensitivity ...

Abstract: This paper proposes a design optimization method using the concept of group technology in order to reduce production cost of products. The design optimization procedures consisting of three ...

Abstract: This paper proposes a multiphase design optimization method using simplified structural models in order to minimize manufacturing cost of machine-tool structures under constraints of machining ...

Abstract: Generally, two types of priorities are considered among multiple objectives in the design of machine structures. One of these objectives is named the “hard objective” and is the absolutely ...

Abstract: This paper proposes a design optimization method in which simplified structural models and standard mathematical programming methods are employed in order to optimize the dynamic characteristics ...
