TAILIEUCHUNG - A procedure for optimal design of a dynamic vibration absorber installed in the damped primary system based on taguchi’s method
The dynamic vibration absorber (DVA) has been widely applied in various technical fields. Using the Taguchi’s method, this paper presents a procedure for designing the optimal parameters of a dynamic vibration absorber attached to a damped primary system. The values of the optimal parameters of the DVA obtained by the Taguchi’s method are compared by the results obtained by other methods. | Vietnam Journal of Science and Technology 56 (5) (2018) 649-661 DOI: A PROCEDURE FOR OPTIMAL DESIGN OF A DYNAMIC VIBRATION ABSORBER INSTALLED IN THE DAMPED PRIMARY SYSTEM BASED ON TAGUCHI’S METHOD Nguyen Van Khang1, *, Vu Duc Phuc2, Do The Duong1, Nguyen Thi Van Huong1, 1 Hanoi University of Science and Technology, 1 Dai Co Viet, Ha Noi Hung Yen University of Technology and Education, Khoai Chau District, Hung Yen Province 2 * Email: Received: 1 February 2018; Accepted for publication: 25 July 2018 Abstract.

INTRODUCTION Taguchi’s method for the product design process may be divided into three stages: system design, parameter design, and tolerance design [1-7]. Taguchi’s method of parameter design is successfully applied to many mechanical systems: an acoustic muffler, a gear/pinion system, a spring, an electro-hydraulic servo system, a dynamic vibration absorber. In each system, the design parameters to be optimized are identified, along with the desired response. The dynamic vibration absorber (DVA) or tuned-mass damper (TMD) is a widely used passive vibration control device. When a mass-spring system, referred to as primary system, is subjected to a harmonic excitation at a constant frequency, its steady-state response can be suppressed by attaching a secondary mass-spring system or DVA. Design of DVA is a classical topic [8-12]. The first analysis was reported by Den Hartog .
