Abstract

For several decades now, NVH (noise, vibration, and harshness) have benefited from the implementation of hydraulic mounts (Flower, I 985). Hydraulic bushings and a variation of a hydraulic mount are widely used in industry. However,the development of cost effective semi-active or active isolation solutions is the next frontier. Moreover, the introduction of cylinder-on-demand technology has intensified the pursuit of a controllable isolator due to the affect it has on engine vibration isolation. Achieving better NVH (noise, vibration, and harshness) comfort necessitates the use of active technologies when product targets are beyond the scope of traditional passive insulators, absorbers, and dampers. Therefore, a lot of efforts are now being put in order to develop various active solutions for vibration control, where the development of actuator is one part. The goal of this thesis is to investigate the optimization of isolators to comply with the transferred force criteria and displacement constraint with the intent to apply this optimization to the design of semi-active isolators. The semi-active bushing is design to isolate a cylinder-on demand engine.
