Design Of Semi-Active Suspension For Aerotransport And Analysis About Comfort

Forest resources are renewable resources in the world today is widely used in and plays an extremely important role in our national economy, however, and the total amount of forest per capita consumption are far below the world average, forestry development still faces enormous pressures and challenges. Forest areas the level of efficiency in transport to some extent, restricted the progress of forestry research. So for high efficiency, high R & D ride transportation equipment is of great significance.This article is designed suspension system inter-forest track conveyor, enhanced transport ride. Mechanical model transport system and its core vibration parameters suspension: calculated static deflection, the elastic stiffness of the original shock absorber damping. And in order to meet the changing different terrain suspension response, designed to switch the semi-active suspension damping.3D model transport aircraft, and the model parameters and simulation analysis and calculation of the input system, using computer analysis of vibration system dynamics. It concluded:compared to rigid connection, the suspension system can greatly reduce vibration to verify the semi-active suspension reached ride requirements. Forest road at the tiny bumpy track conveyor there have flexible, stable characteristics of security operations.In this paper, theoretical analysis, computer simulation and experimental study of a combination of methods, the vibration characteristics of the conveyor system of forestry research. Independent design forestry transport aircraft prototype, analysis and research by transport vibration theory of its vibration characteristics. The establishment of a transport model based around test prototype suspension in different terrain, different vibration acceleration loads and different driving speeds. Condition factor for different conveyor vibration damping has different degrees of impact.Using Solidworks software for the forest skidding conveyor and self-help system solid modeling, assembly, the existence of forest skidder transports interference three-dimensional model of the assembly process by an interference detection module testing, in order to facilitate timely correction; on this basis, with multi-body dynamics analysis software ADAMS established four degrees of freedom of the vehicle body vibration model plane. The model can be used for simulation of transport suspension parameters and uneven pavement incentive effect on ride comfort. And a comparative study of the optimal suspension parameters with the existing suspension parameters of two typical operating conditions corresponding to the transport vibration. The results show that the parameters best match suspension can greatly improve the. condition of the vibration conveyor, the optimization results can be directly applied to improve the design guide conveyor suspension system.
