Specific embodiment
Specific embodiments of the present invention will be described in detail with reference to the accompanying drawing.
In one embodiment of the present of invention, as shown in Figs. 1-5, a kind of suspension type single track car body strength test dress is provided It sets, including door frame 2, door frame 2 includes several columns 21 and crossbeam 22, and column 21 is fixedly installed on the ground, and 22 activity of crossbeam is set It sets between column 21, crossbeam 22 can move up and down between column 21, and single track car body 1, single track car body are provided with below door frame 2 1 top is connected by several vertical actuator 3 and crossbeam 22, is symmetrical arranged at the top of single track car body 1 there are four vertical actuator 3, 1 two sides of single track car body are symmetrically arranged with several lateral actuator 4, are symmetrically arranged with totally four transverse directions at left and right sides of single track car body 1 Actuator 4, lateral 4 other end of actuator and column 21 connect, and 1 top rear and front end of single track car body is provided with hitch attachment base 7, It is provided with longitudinal actuator 5 on hitch attachment base 7, is provided in vertical actuator 3, lateral actuator 4 and longitudinal actuator 5 Force snesor, force snesor are PG205-B type tensile stress sensor, are provided with several counterweights 6 in single track car body 1.
Suspension type single track car body strength test device provided by the invention can effectively guarantee suspension type single track car body 1 Freedom degree, at the same it is as much as possible simulate installation and operation mode and route operating condition, can not only carry out the quiet strong of single track car body 1 Degree test, can be with analog line to the vibrational state of single track car body 1.This experimental rig is directed to suspension type single track car body for the first time 1 establishes dedicated strength test scheme, and for experimental rig before, test is convenient and efficient, and specific aim is stronger, test It is more efficient, and special item can be carried out for suspension type car body;The way of restraint is consistent with actual installation situation simultaneously, obtains The test data arrived is truer, provides relatively reliable test data for the design and maintenance of suspension type car body and track girder; When test of static strength, the present apparatus can measure the 6 weight number of weight and counterweight of vehicle by the force snesor in vertical actuator 3 According to, the load data under the conditions of various counterweights has really been obtained, it is more true, reliable;When fatigue test, vertical actuator 3, lateral actuator 4 and longitudinal actuator 5 provide the oscillating load of 1 all directions of single track car body, can apply not closing at position Same load can carry out the fatigue test of car body in relatively simple frame, and experimental rig is easy to be reliable, preferable to simulate 1 freedom degree of single track car body, and cost is relatively low, can carry out multiplicating test.
When test, single track car body 1 is hung on the crossbeam 22 of door frame 2 by four vertical actuator 3 first, in door frame Connection is connected on the hitch attachment base 7 at car body both ends there are four lateral actuator 4 between 2 column 21 and single track car body 1 Two longitudinal actuator 5;When test of static strength, by increasing counterweight 6 in single track car body 1, to simulate multiplying in single track car body 1 Objective weight, then 7 position of hitch attachment base to single track car body 1 carry out longitudinal loading application, come simulate single track car body 1 by Longitudinal force, while stress when single track car body 1 is tested can be read by the force snesor of each actuator, it is track girder Design with single track car body 1 provides the load data under working condition;When Stromeyer test, mould is configured in single track car body 1 Then the counterweight 6 of quasi- passenger weight provides Fatigue Vibration load by vertical actuator 3, lateral actuator 4 and longitudinal actuator 5, The application of dynamic load is carried out according to the loading spectrum of car body, to simulate the vibration that single track car body 1 is subject to, after certain number, is led to Cross whether detection car body cracks result to judge car body fatigue test.During the test, by increasing and decreasing single track car body 1 In counterweight 6 carry out passenger in simulating vehicle operational process bring weight increase and decrease up and down, while crossbeam 22 can be It is moved up and down between column 21, adjusts its height to adapt to the car body of different height, single track car body 1 in a variety of situations can be simulated Operating condition, it is easy to adjust, for single track car body 1 design strong foundation is provided.The present invention is from vertical, horizontal and vertical for single track Car body 1 provides oscillating load, simulates the real conditions of single track car body 1 in operation, efficiently solving single track car body 1 can not be true The freedom degree of real reaction car body, the load that key position can not be applied and cannot simulation test operating condition as much as possible.
Although being described in detail in conjunction with attached drawing to a specific embodiment of the invention, should not be construed as special to this The restriction of the protection scope of benefit.In range described by claims, those skilled in the art are without creative work The various modifications and deformation that can make still belong to the protection scope of this patent.
