Abstract
The invention discloses a cutting type energy absorption method for a rail locomotive vehicle. An energy absorption element arranged on a protected object is adopted in the method, and the energy absorption element comprises a cutting knife and a cut piece; and when an impact source is contacted with the energy absorption element, the acting force of the impact source pushes the cutting knife to cut a cutting layer arranged on the cut piece, the energy of the impact source is converted at the same time of cutting work, the strength of the impact source is decelerated and buffered, the energy of the impact source is gradually consumed, and the damage effect of the impact force on the protected object is relieved and reduced. The cutting speed of the cutting force in the cutting work and impact source energy consumption processes is first quick and then slow in the whole impact process, the approaching speed of the impact source and the protected object is gradually reduced, the approaching time of the impact source and the protected object is prolonged, and the actual acting force of the impact source on the protected object is reduced. The method is applicable to the rail locomotive vehicle, an automobile or other equipment object.
Description
Technical field
The present invention relates to a kind of method of rail locomotive vehicle cutting type energy-absorbing.
Background technology
At present, being used for the vehicle, as the energy absorption device that uses on guideway vehicle, the automobile, is the element that adopts energy-absorbing basically.Its absorption cell mainly contains hydraulic part or crushable element.Its weak point, the easy of hydraulic part leaked, and energy-absorbing was lost efficacy, and the energy-absorbing stroke of crushable element is limited.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide that a kind of volume is little, the method for the rail locomotive vehicle cutting type energy-absorbing of reliable operation.
Purpose of the present invention is achieved by following technical proposals: described method comprises the employing power-absorbing, and power-absorbing is installed on the protected object, and when protected object was subjected to extraneous bump source strong impaction, what at first contact with the bump source was power-absorbing; Described power-absorbing comprises bite and is cut part; When the bump source touches power-absorbing; the application force promotion bite in bump source will be set in the cutting lay that is cut on the part and cut; in above-mentioned cutting acting; energy to the bump source is changed; intensity to the bump source is carried out deceleration buffer; progressively consume the energy in bump source, mitigation also reduces the destructive effect of impact to protected object.
The cutting rate of described bite in cutting acting, consumption bump source energy process; in whole knockout process, be first quick and back slow; progressively reduce the close velocity of bump source and protected object; prolong bump source and protected object near the time, reduce the actual force of bump source to protected object.
Described cutting rate be to realize first quick and back slow by size, shape, knife number and the arrangement thereof of setting bite.
Described cutting rate be to form by the combination of materials that setting is cut the shape of part or cross section or different mechanical specialitiess to realize first quick and back slow.
Described cutting rate be to realize first quick and back slow by changing cutting output.
Compared with prior art, the present invention has the following advantages: little, the reliable operation of volume, energy-absorbing effect is good.Be suitable on the automobile of the large-scale vehicle such as rail locomotive vehicle, various models or other equipment objects, using.
The specific embodiment
The invention will be further described below in conjunction with embodiment:
Method of the present invention: described method comprises the employing power-absorbing, and power-absorbing is installed on the protected object, and when protected object was subjected to extraneous bump source strong impaction, what at first contact with the bump source was power-absorbing; Described power-absorbing comprises bite and is cut part; When the bump source touches power-absorbing; the application force promotion bite in bump source will be set in the cutting lay that is cut on the part and cut; in above-mentioned cutting acting; energy to the bump source is changed; intensity to the bump source is carried out deceleration buffer; progressively consume the energy in bump source, mitigation also reduces the destructive effect of impact to protected object.
The cutting rate of described bite in cutting acting, consumption bump source energy process; in whole knockout process, be first quick and back slow; progressively reduce the close velocity of bump source and protected object; prolong bump source and protected object near the time, reduce the actual force of bump source to protected object.
Described cutting rate be to realize first quick and back slow by size, shape, knife number and the arrangement thereof of setting bite.
Described cutting rate be to form by the combination of materials that setting is cut the shape of part or cross section or different mechanical specialitiess to realize first quick and back slow.
Described cutting rate be to realize first quick and back slow by changing cutting output.
The inventive method is the cutting type energy-absorbing method, and its cardinal principle is:
1, the cutting type endergonic process is the process of a transformation of energy, is interior can being consumed that the kinetic energy that the source is clashed in the external world is changed into heat energy and cutting acting, has reduced the extent of injury of extraneous impact to protected object, has realized the purpose of cutting energy-absorbing.
2, the cutting type endergonic process is the process of impact buffering to external world; cutting rate design first quick and back slow; be equivalent between protected object and extraneous bump source, be provided with a deformable body; this deformable body can progressively reduce the close velocity of bump source and protected object; prolong bump source and protected object near the time, reduce the application force of bump source to protected object.
