Abstract: Hydraulic engine mount is basically used to damp the vibrations so that the applications, for which it is used, can run safely. For Agricultural applications such as power weeder, grass trimmer Hand Arm Vibrations (HAV) are experienced by the operator continuously. It is also observed that some agricultural equipment has no any vibration isolation device to damp these excessive vibrations. Conventional mounts such as rubber mounts fail to provide better performance during damping vibrations due to some limitations. These troubles are overcome by hydraulic engine mount. In this work, a new configuration of hydraulic engine mount is designed for vibration isolation. The incorporation of solenoid actuator makes the passive mount to active engine mount. The experimentation of hydraulic engine mount is done on designed test rig by using FFT analyzer. The performance of neoprene rubber mount as compared to hydraulic mount is not adequate. The results of passive and solenoid actuated mount are compared by measuring vibration parameters. All values of acceleration are safe when compared with maximum theoretical value of acceleration. The result shows that designed hydraulic engine mount is beneficial for vibration isolation. The developed model can be used for designing the vibration control system for agricultural applications.
