Description
Technical field
The present invention relates to a kind of method and apparatus of the connection element for monitor vehicle.
Background technology
The connection element of vehicle, easily there are wearing and tearing or aging in such as spring element or Connection Element.Use current prior art, the wearing and tearing of connection element and aging during vehicle operating cannot be prevented.Therefore, in maintenance range, every regular time or after vehicle travels how many kilometers, these connection elements must be changed.The wearing and tearing of these connection elements or agingly can affect its material properties.Three major causes of the change of these material properties are: running time, environment be impact and mechanical strees initiatively.These three major causes can cause overall damage to connection element, and the damage rate of each connection element is different again.
The connection element of vehicle can be subject to large-scale mechanical strees.These mechanical streess depend on that corresponding operating pattern and vehicle travel road conditions.In addition, these three major causes that material properties changes show non-linear damage behavior, thus make to expect that overall damage is unpredictable.
According to prior art, therefore maintenance time point is not limit on the basis that the actual entirety of connection element is damaged, but on certain milimeter number basis of vehicle, since upper once maintenance process a concrete time span after, or to limit with its array mode.
Therefore, the vehicle connection element that still can use inside vehicle may be replaced in maintenance range.
Although also likely the connection element of vehicle, also in use, no longer meets the demands with regard to its overall damage.
Summary of the invention
Technical purpose
The object that the present invention is basic is to provide a kind of connection element for monitor vehicle should the method and apparatus of the property used to limit it.
Technical scheme
According to the present invention, can be achieved this end by a kind of method, in this approach, for connection element determination main phase to be monitored is to moving direction, measure and store connection element to be monitored along the relative movement of described main phase to moving direction, and assessment is performed to the relative movement stored.
Connection element can be specifically embodied as diversified design.According to the design of connection element and the power that operatively acts on connection element to determine that main phase is to moving direction.For connection element to be monitored, may only a relative movement direction be defined as being main, but, also can determine that multiple main phase is to moving direction for each connection element.
Measure and store connection element to be monitored along at least one main phase described to the relative movement of moving direction.Then the relative movement stored is assessed.
Connection element performs relative movement because of mechanical strees, and described relative movement causes damage to connection element.
The advantage of method of the present invention is as follows: by measuring and assess these relative movements, can determine whether connection element still meets the demands, or determine the damage rate of connection element.Therefore, except during maintenance, also can determine at any time connection element in vehicle should the property use, and, in maintenance range, necessary, can rapidly to the connection element implementation replacing damaged.
Another advantage of method of the present invention is, in maintenance range, those can in fact be determined the connection element be damaged by method of the present invention in a replacing vehicle.
In the preferred embodiment of method of the present invention, in each case by the sensor arranged moving direction along main phase and the relative movement measuring and store connection element to be monitored from equipment.
Sensor and can changing along this main phase the distance of moving direction between equipment.Therefore, main phase can be measured and be stored in all relative movements on moving direction.
In another preferred embodiment of method of the present invention, store the number of connection element to be monitored relative movement more than the threshold value limited in advance.
The each relative movement of connection element more than threshold value is all counted a standard unit equivalently.The relative movement of connection element below threshold value is then disregarded interior.Such counting provides the information relevant with the number of the relative movement being greater than threshold value.
Therefore, the sensitivity of method of the present invention can be set, and if the relative movement of connection element does not obviously cause damage to connection element, then can filter out such relative movement.
The feature of the preferred embodiment of method of the present invention is, is compared, perform assessment to the relative movement of the storage of connection element to be monitored by the number of the relative movement by storage with at least one limit value limited in advance.
If the number of the relative movement stored exceedes at least one in the limit value limited in advance, then this shows, connection element no longer meets the requirements because receive damage.
When not contacting receiving element, transmit the relative movement stored.
Therefore, in vehicle operating process, or in vehicle travel process, also can transmit to receiving element the relative movement stored.
Preferably, in each case after the time gap of substantially the same length, or after substantially the same car kilometer number, assessment is performed to the relative movement of the storage of connection element to be monitored.
Suppose in the time gap of this equal length, or in each case after identical car kilometer number, the size acting on the power in the device on connection element is identical.
By comparing in corresponding time point place or the relative movement stored after corresponding milimeter number and the relative movement stored before these corresponding time points or before this corresponding milimeter number, the damage to connection element can be determined.
Preferably, on the basis measuring running data or on the basis of vehicle emulation, this threshold value and/or this limit value is limited.
Can traveling data analysis measured in conjunction with the threshold value and/or the limit value (limit value or multiple limit value) that the basis of damage model produce the different damage rates corresponding to connection element to be tested.
Also the measurement running data of vehicle can be emulated virtually therefore to produce limit value virtually.
At vehicle testing run duration, assess the relative movement of connection element to be monitored, and limit threshold value, thus only store those connection element relative movements connection element being caused to larger damage.Limit value corresponding to different damage rate is defined as, if the number of the relative movement of connection element exceedes these limit values, then relative to parts should with the state classification of property to these parts.Therefore, each connection element represents maybe should use sexual state a kind of service life, as a result, can plan accurately maintenance intervals, and therefore can use parts in an optimal manner.
Limit a last limit value, if make the number of the relative movement of connection element exceed this limit value, then owing to being damaged, so connection element no longer meets the requirement between power actuated vehicle used life.
Connection element to be monitored is preferably embodied as spring element, Connection Element or its combination.Such as, this term of connection element should be understood to the combination of two spring elements, two Connection Elements, spring element and Connection Elements, or also has and anyly comprise multiple spring element, Connection Element or the combination of both.
Vehicle is preferably embodied as guideway vehicle.Can prevent from carrying out unnecessary maintenance to guideway vehicle by method of the present invention.Therefore, this point is especially favourable, because guideway vehicle repairs must need relatively high technical expense.And during the maintenance period, corresponding guideway vehicle can not be used for normal running.
By performing assessment to the relative movement stored of connection element to be monitored, preferably maintenance time can be limited.
Therefore, can with accurately determining that the mode of time limits maintenance date.
By assessing the relative movement stored of connection element to be monitored, particularly can analyze relative to the stress of the operational orientation on connection element operation mode.
By limit limit value or threshold value time in conjunction with this analyze result, the accuracy rate of method of the present invention can be improved constantly.Therefore a learning process can be produced.In addition, these results also can affect the new development of connection element.
