THE SIMULATION SYSTEM OF THE RAFT VIBRATION-ISOLATING UNIT

摘要

The raft vibration-isolating unit is a device that can reduce noise of the machinery effectively. Should it be designed perfectly, it can decline energy of vibration about 35 or 40 dB. The preliminary designing and structure selecting for the raft vibration-isolating unit are very complicated and over-elaborate. Should it not planned carefully enough; it cannot meet the requirement of the performance targets, wasting a lot of manpower and material resources. So, a simulation system of the raft vibration-isolating unit has been built. Given the technical design of the selected floating raft isolating unit, its structural parameters, the number of vibration isolators and their installation positions, the simulation system can calculate the natural frequencies, vibration modes, the attenuation result, modular state, stability and anti-shock performances, simulate the shock response, dynamic response of the unit. And also, the simulation system can display the design effect of the selected scheme vividly.
