An Analysis Of The Safety Of A Driver Of A Thunderstorm

With continuous development and innovation of the global military technologies, and the constant update of the mines’ types, the mines’ explosion’s effect brisance and the destruction gain a large improvement and development. Therefore the modern anti-mine vehicle should be advanced with the times, and have a continuous improvement. It will make its anti-vibration be improved and the car’s safety has also been increased, in order to protect the drivers and passengers’ safety perfectly. Although, the key skills’ improvements are the vehicles’restrains system (safety airbag, safety belt and so on) and the anti-vibration system. Presently, car’s vibration system consists of three main parts in the world. They are tire, suspension, seats system and so on.Seat’s anti-vibration system is an important part of the car’s anti-vibration system. It affects the drivers’ safety directly. Although, the cost of traditional linear passive anti-vibration element (such as spring) is low, the anti-vibration frequency range is too small. What’s more, the autonomic adaption is too poor. The effect of new anti-vibration element which is controlled by active and semi-active controlling means is good, but the consumed energy is too high and the control of the system is inconvenient. While, the new nonlinear passive anti-vibration elements overcome the shortcomings of two anti-vibration elements which are described above. It is the positive and negative stiffness parallel spring element. Nevertheless, for vehicle restraint system, the safety airbag is an integral part to protect the drivers’safety. Thus, the research and analysis in this paper contains the cab’s dynamic response of the anti-mine military, the parameters optimization about positive and negative stiffness springs of the anti-mine military car’s seat, the simulation of the car’s semi-active seat suspension using Sky-hook control method, the simulation of the car’s semi-active seat suspension using PID-Sky-hook control method and the dynamics simulation of the car’s safety airbag. The result of simulation indicates that it can reduce the drivers’ hurts which are produced by the shock wave of the mine’s explosion. And the driver’s safety of the anti-mine military vehicle is improved.
