The invention discloses a suspension control method for equipment under a railway vehicle. The suspension control method comprises the steps that the root-mean-square value and the maximum vibration frequency of vehicle body vibration are obtained in real time; a relationship between the root-mean-square value and a preset threshold value is judged; and when the root-mean-square value is larger than a preset threshold value, suspension parameters of suspension equipment used for suspending the under-vehicle equipment are determined according to the maximum vibration frequency, the mass of thevehicle body and the mass of the under-vehicle equipment, wherein the suspension equipment is suspension parameter adjustable equipment. By reasonably utilizing the under-vehicle equipment, the under-vehicle equipment and the suspension equipment serve as a dynamic vibration absorption system for vehicle body vibration, when the vehicle body vibrates, the under-vehicle equipment and the suspensionequipment can absorb part of vibration energy of the vehicle body, the purpose of reducing vehicle body vibration is achieved, and the riding comfort of passengers is improved. In addition, the invention further provides a control device and system with the advantages.
Description
technical field [0001] The present application relates to the field of rail transit vehicles, in particular to a suspension control method, device and system for under-vehicle equipment of rail vehicles. Background technique [0002] When rail transit vehicles are running, the wheel-rail vibration generated by track irregularities will be transmitted to the vehicle body, affecting the comfort of passengers in the vehicle. On the other hand, the vibration generated by the large under-vehicle equipment (such as transformers and converters) suspended on the side beams of the rail transit vehicle body will also be transmitted to the car body, further affecting the ride comfort of the passengers in the vehicle. [0003] At present, rubber gaskets are set between the under-vehicle equipment and the vehicle body, so that the under-vehicle equipment is directly suspended on the side beams of the vehicle body in an elastic suspension manner, and the elasticity of the rubber gaskets i...
