Abstract

Noise emission from axial piston machines has been studied for several decades by many researchers and pump manufacturers. Different design methods for reducing the sources of pump noise have been proposed and are in use. The authors have studied and compared the effectiveness of several passive design methods. This paper presents a short overview of the existing design methods. The challenges in reducing both fluid borne noise sources (FBNS) and structure borne noise sources (SBNS) in a unified way are discussed. A computer aided multi-objective optimization procedure, which helps minimize the pump noise sources in a broad operating range, has been proposed by the authors. The optimization procedure is described in detail along with the mathematical model of the pump in this paper. An important contribution of the multi-objective parameterized approach is that the compression and the expansion region of the valve plate are simultaneously optimized unlike most previous works which consider compression and expansion separately. The parameterization of the valve plate is also explained. A case study and noise level measurements to prove the effectiveness of the optimization procedure are included.
