Abstract
A bicycle damping front fork vertical fatigue testing machine is composed of a controller, a linear motor, a force sensor, a front fork clamp, a force application clamp and a frame. The linear motor is installed on the frame, and a mover of the linear motor is equipped with the force sensor and is connected with the force application clamp through the force sensor; the front fork clamp is installed on the frame and used for installing a bicycle damping front fork test piece; and the controller is electrically connected with the linear motor and the force sensor respectively. The bicycle damping front fork vertical fatigue testing machine of the invention can satisfy the requirements of 'bicycle damping front fork vertical fatigue test' in a QB1881--2008 'bicycle front fork' standard, and especially, the frequency for load applying is satisfied while the force application precision of the testing machine is ensured.
Description
Affiliated technical field
The present invention relates to a kind of " front suspension fork of bicycle is vertically to the fatigue tester " that can meet " front suspension fork of bicycle is vertically to torture test " requirement in QB1881--2008 < < bicycle front fork > > standard, especially can, in warranty test machine application of force precision, improve the frequency of imposed load.
Background technology
In QB1881--2008 < < bicycle front fork > > standard to " front suspension fork of bicycle is vertically to torture test ", except the load of having stipulated to apply, also stipulated that maximum test frequency should be 25HZ.But still there is no special-purpose front suspension fork of bicycle vertically to fatigue tester at present, in the time of need testing, generally can only replace with cycle frame fatigue tester operation inconvenience; Simultaneously at present the force application system of known various bicycle assembly parts fatigue testers generally forms by application of force cylinder or hydraulic cylinder, control system, power sensor; Because pneumatic or hydraulic pressing system are stressed and the restriction of cylinder diameter, its movement velocity is lower, generally the highlyest can only reach 3-5HZ, cannot meet the requirement that maximum test frequency should be 25HZ.
Summary of the invention
In order to make up, there is no at present special-purpose front suspension fork of bicycle vertically to the shortcoming of fatigue tester, overcome the low problem of existing bicycle assembly parts fatigue tester force application system frequency, the front suspension fork of bicycle that the invention provides the requirement of " front suspension fork of bicycle is vertically to torture test " in a kind of QB1881--2008 of meeting < < bicycle front fork > > standard, simultaneously also can meet maximum test frequency is vertically to fatigue tester simultaneously.
The technical solution adopted in the present invention is: by controller, linear electric motors, power sensor, front fork fixture, application of force fixture, frame, form front suspension fork of bicycle vertically to fatigue tester.Described linear electric motors are arranged in frame, and on the mover of linear electric motors, installing force sensor also connects application of force fixture by power sensor; Described front fork fixture is arranged in frame for front suspension fork of bicycle test specimen is installed; Described controller is electrically connected to linear electric motors, and power sensor is electrically connected to controller.
When controller drives linear electric motors motion, the mover of linear electric motors by power sensor and application of force fixture to being arranged on the front suspension fork of bicycle test specimen imposed load between application of force fixture and vertical tube of front fork fixture, the variation that power sensor is exerted oneself according to the size detection of imposed load thrust, then convert electric signal to and be sent to controller, controller, according to this signal and the predetermined load applying, is controlled the motion of linear electric motors; When reaching predetermined imposed load, controller drives linear electric motors to return.And so forth, realize front suspension fork of bicycle vertically to torture test.
The invention has the beneficial effects as follows, owing to having adopted linear electric motors force application system that the dynamic response performance of this testing machine is improved, thereby improved the frequency of imposed load; And native system is simple in structure, easy to maintenance, when meeting test frequency, improved the reliability of control system.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. controllers in figure, 2. linear electric motors, 3. power sensor, 4. application of force fixture, 5. vertical tube of front fork fixture, 6 frames; 7. front suspension fork of bicycle test specimen
Embodiment
In Fig. 1, controller (1) is electrically connected to straight-line electric dynamo-electric (2), and power sensor (3) is electrically connected to controller (1); Linear electric motors (2) are arranged in frame (6), the mover push rod of linear electric motors (2) and power sensor (3) mechanical connection, and connect application of force fixture (4) by power sensor, it is upper that vertical tube of front fork fixture (5) is arranged on frame (6), for front suspension fork of bicycle test specimen (7) is installed.
Before test starts, the standpipe of front suspension fork of bicycle test specimen (7) is installed on to vertical tube of front fork fixture (5).While starting to test, controller (1) drives linear electric motors motion, the mover of linear electric motors (2) by power sensor (3) and application of force fixture (4) to being arranged on front suspension fork of bicycle test specimen (7) imposed load between application of force fixture (4) and vertical tube of front fork fixture (5); The variation that power sensor (3) is exerted oneself according to the size detection of imposed load thrust, then converts electric signal to and is sent to controller (1), and controller (1), according to this signal and the predetermined load applying, is controlled the motion of linear electric motors (2); When reaching predetermined imposed load, controller (1) drives linear electric motors (2) to return.And so forth, realize front suspension fork of bicycle vertically to torture test.
Claims (1)
1. the front suspension fork of bicycle based on linear electric motors, vertically to a fatigue tester, is characterized in that comprising controller, linear electric motors, power sensor, front fork fixture, application of force fixture, frame; Described linear electric motors are arranged in frame, and on the mover of linear electric motors, installing force sensor also connects application of force fixture by power sensor; Described front fork fixture is arranged in frame; Described controller is electrically connected to linear electric motors, and power sensor is electrically connected to controller.
