“…Structural-acoustic optimization frequently takes the minimum structural weight as an objective function and the acoustic pressure at the design field points and either the total acoustic radiation pressure of the structures as or the minimum acoustic intervention as an objective while the structural weight as the constraint condition [22]. Zhang et al [46,47] executed the optimal geometric design of the structures to minimize the acoustic pressure at positions and frequencies of interest using the feasible direction method and the acoustic interference characteristics were utilized-based on the 3-D FEM model with the direct method. The aim of work by Wang et al [38] was to apply the robust design method to structural-acoustic systems to appraise the situation the uncertainties in the structural or acoustic parameters.…”

A survey on current design and optimization of coupled-structural acoustic systems (OCSAS) is presented. It reinforces different terminologies and methods in this field. General concepts are shortly defined, and literatures are reviewed for further investigation. Although surveys of optimization for coupled-structural acoustic systems are common, they are frequently incomplete in terms of extensive scope general applicability to engineering design. For instance, many surveys only target determined applications while others only mention the critical literature in the field. Outcomes are drawn that represent often-neglected ideas and applicability to engineering problems. It has been found that no single approach is outstanding. On the contrary, the selection of a determined method depends on the type of knowledge that is supplied in the problem, the user's preferences, the solution necessaries, etc. Also, new emerging research fields are introduced.

“…. It can be seen from this figure that the isolator is one type of wedge mount, whose stiffnesses in three principal axes can be adjusted by changing the dimension and the angle of the two adjacent rectangle rubber blocks (also named as rubber springs). It can also be seen from Fig.…”

“…Rubber isolators are widely used in vehicles to control the motion of the powertrain, to depress the vibration of the powertrain under road excitation and to isolate the engine vibration transmitted to car body or subframe . Rubbers offer the advantage of withstanding very large strains but without permanent deformation or fracture, which makes them ideal to be used in vibration control and isolation of a powertrain.…”

A method for modelling fatigue life of rubbers and rubber isolators is presented in this paper. Firstly, a fatigue experiment is carried out for a rubber dumbbell cylindrical specimen and a rubber isolator. Based on the finite element analysis, the damage parameters including the strain energy density, the maximum principal Green–Lagrange strain and the effective stress are calculated and discussed. Secondly, three fatigue life prediction models are established by using the three damage parameters and using the relation between the measured fatigue life of a dumbbell cylindrical specimen and the computed value of the damage parameters. Thirdly, three proposed prediction models are used to investigate which one can be best used to predicting fatigue life of rubber isolators, taking a typical powertrain rubber isolator as studying example. The fatigue lives of the rubber isolator predicted by the three models are compared with the experimental life. The results demonstrate that the predicted fatigue lives of the rubber isolator using the three fatigue models agree well with the experimental fatigue life within a factor of four, and the model using the effective stress as the damage parameter can predict the fatigue life within a factor of two, which has the best accuracy among the three models.

“…From the published papers, design methods for other different mounting systems are studied, which can be references for CRFM mounting system. In the powertrain mounting system (PMS), mount stiffness at linear section in three directions of its local coordinate system (LCS), mount locations and orientations can be obtained by optimisation of the natural frequencies, energy distributions of the powertrain rigid mode (Liu and Shangguan, 2014;Shangguan, 2009;Yu et al, 2001;Shangguan and Chen, 2012;El Hafidi et al, 2010). Mount stiffness at non-linear sections and its tuning points in the force vs. displacement curve are determined by powertrain motion control strategies (Shangguan and Hou, 2006).…”
