Description

Most of the domestic urban railways are concrete tracks, and track support stiffness (usually TSS), which directly affects track performance, is negligible because it is a rail pad (which is extremely small compared to a vibration pad) (Hereinafter referred to as " elastic pad ") and the like. Therefore, the aged elastic material increases impact load and vibration transmitted to the structure including the rail, resulting in deterioration of ride quality, causing civilization and orbital failure.

Since the elastic pad is aged (deteriorated) due to the accumulation of the period of use, the function is lost, and maintenance such as timely condition evaluation and replacement is very important. However, the maintenance of the current elastic material is the vertical spring stiffness test which is carried out in the outside laboratory by collecting the elastic pads attached to the field. For this experiment, remove the rail fastening at the site and remove the elastic pad But also the construction of expensive, dangerous and complicated processes.

Therefore, for economical and efficient maintenance of elastic materials, introduction of a new concept device or system that can easily evaluate the performance and condition of the elastic material at a desired position during nightly inspection time and monitor performance change (deterioration) need.

Hereinafter, the operation of the load generator controller 300, which can be implemented differently according to the embodiments, will be described in detail with reference to the accompanying drawings.

6 is a flowchart illustrating an operation control of the load generator controller 300 according to the embodiment of the present invention. When the load generator controller 300 determines that the operation program installed in the manager computer 400 The load generator 200 is controlled according to the control of the program.

A person who wants to measure and evaluate the performance of the railway track elastic material using the portable performance test evaluating apparatus according to the embodiment of the present invention moves to a desired measurement position (point) and fixes the load generator 200 to the rail rail 100. That is, the rail fixing portions 210 and 220 are positioned at both ends of the arched body frame 205, and the arched body frame 205 is formed in a state in which the rotary type fixing pieces 212 positioned in the diagonal direction are unlocked. The rail fixing portions 210 and 220 of the rail type rail assembly 100 are coupled to the head portion 110 of the rail rail 100 to rotate the rotary type fixing pieces 212 to the locking position. The load generator 200 is fixedly coupled to the head 110 of the railway rail 110.

Thereafter, the operator electrically connects the load generator 200 and the load generator controller 300, and manually operates the actuator 230 to move the resilient jig 240, which is coupled to the lower end of the actuator 230, (Not shown). The movement of the actuator 230 may be controlled so that the load generator controller 300 contacts the upper surface of the head 110 of the rail rail 100 with the force jig 240.

When the precondition for measuring and evaluating the performance of the railway track elastic material is completed, the manager operating the manager computer 400 issues an initialization command through the UI screen provided by the operation program. The initialization command is transmitted to the load generator controller 300 through short-range wireless communication.

When the initialization command is received (S10), the controller 320 of the load generator controller 300 sets the current position of the actuator 230 to the initial (reference) position (S20) through the actuator displacement detection unit Step).

The control unit 320 controls the actuator 230 of the load generator 200 to apply a load to the rail 100 in step S30. The applied load can be gradually increased within the range of 0 kN to 70 kN.

In this manner, while the load is applied to the railway rail 100, the control unit 320 obtains the amount of displacement of the actuator by the applied load through the actuator displacement detection unit (step S40). That is, the position value (mm) of the actuator 230 moved from the initial position is obtained according to the application of the load.

The controller computer 400 acquires the amount of displacement of the actuator according to the load applied to the actuator 230 and transmits the displacement to the manager computer 400 in step S50. It is possible to evaluate the orbital support stiffness of the locally placed railway orbital elastic material and to evaluate the aging level of the elastic material. This performance evaluation will be described in more detail with reference to FIGS. 7 to 9. FIG.

The control unit 320 receives the programmed load from one point to the railway rail 100 and obtains the amount of displacement of the actuator 230. The control unit 320 then controls the actuator 300 to separate the load generator 200 from the railway rail 100 230 to the standby position (S60). Of course, if the program is programmed to perform two or three repetitive evaluations for more accurate performance evaluation, the actuator 230 may be controlled to move to the initial position (return to the initial position while decompressing).

For reference, since the structure of the railway track to be managed differs according to the railway operating organization before the initialization command, it is possible to further include a step of making a representative template for the predefined track structure and allowing the manager to select from the elastic material performance evaluation program have. It is also possible to input the specification of the selected line and the specification of the line according to the format of the selected orbit structure.

And further selecting a type of test. The type of test is divided into static test and dynamic test. When static test is selected, the size of test load, speed of penetration, number of tests and so on can be set. If dynamic test is selected, Frequency, and number of repetition of the load.

The load model of the dynamic test can be implemented with a sine wave or triangle wave type load and the program can be implemented so that the load data and the sampling frequency of the measurement signal can be set by the administrator.
