Abstract
A fatigue testing machine of a bicycle handlebar is composed of a controller, a linear motor, a force sensor, a linear motor support, a handlebar horizontal pipe clamp, a handlebar stand pipe clamp and a rack. The controller, the linear motor, the force sensor and the handlebar horizontal pipe clamp form a force application system, and the two force application systems are arranged on the rack parallelly. Because the linear motor is employed as the force application system, the dynamic response performance of the testing machine is improved substantially, and the frequency of an applied alternating load is improved. Meanwhile, the fatigue testing machine of the bicycle handlebar is simple in structure and convenient in maintenance, and enables the reliability of a control system to be improved while satisfying a test frequency.
Description
Affiliated technical field
The utility model relates to a kind of bicycle handle bar fatigue tester, especially can, in warranty test machine application of force precision, improve the frequency that applies alternate load.
Background technology
At present in the standards such as GB3565-2005 " bicycle safe requirement ", EN14764:2005 " City and trekking Bicycles-Safety requirements and test methods " to the torture test of handlebar strength of parts except the power value of having stipulated imposed load and test number (TN), also stipulated that maximum test frequency should be 25HZ.But the force application system of at present known testing machine generally forms by application of force cylinder or hydraulic cylinder, control system and power sensor, because the power value of the required imposed load of test is larger, pneumatic or hydraulic pressing system is stressed and the restriction of cylinder diameter, its back and forth movement frequency is lower, generally the highlyest 3-5HZ can only be reached, the requirement that maximum test frequency should be 25HZ can't be met.
Summary of the invention
In order to overcome the low problem of existing bicycle handle bar's fatigue tester test frequency, the utility model provides a kind of testing machine that meets the maximum test frequency of handlebar strength of parts torture test.This testing machine, when guaranteeing application of force precision, has improved the frequency of test.
The technical scheme that the utility model adopts is: by controller, linear electric motors, power sensor, linear electric motors support, transverse tube fixture, handle riser fixture, frame are formed to bicycle handle bar's fatigue tester.Described linear electric motors are arranged on frame by the linear electric motors support; One end of described power sensor is connected with the mover of linear electric motors, the other end with the transverse tube fixture is connected; Described handle riser fixture is arranged on frame; Described controller is electrically connected to linear electric motors, and the power sensor is electrically connected to controller; Described linear electric motors, power sensor, the transverse tube fixture is formed to force application system, two parallel being arranged on frame of force application systems.
When controller drives the linear electric motors motion, linear electric motors by dynamometer and the transverse tube fixture to being arranged on the test specimen imposed load between transverse tube fixture and handle riser fixture, the variation that the 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 the power value signal of this signal and predetermined imposed load, is controlled the motion of linear electric motors; When imposed load reaches the predetermined load value applied, controller drives the linear electric motors drawback movement, carries out reverse imposed load, when reaching the predetermined load value oppositely applied, controller drives linear electric motors drawback movement again, and so forth, realizes bicycle handle bar's torture test.
The beneficial effects of the utility model are, owing to having adopted linear electric motors as force application system, the dynamic response performance of this testing machine are improved greatly, have greatly improved the frequency that applies alternate load; Native system is simple in structure, easy to maintenance simultaneously, when meeting test frequency, has improved the reliability of control system.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural drawing of the present utility model.
1. controllers in figure, 2. linear electric motors support, 3. linear electric motors, 4. power sensor, 5 the transverse tube fixture, 6. handle riser fixture, 7. frame, 8. handlebar test specimen
Embodiment
In Fig. 1, linear electric motors (3) are arranged on frame (7) by linear electric motors support (2); One end of described power sensor (4) is connected with the mover of linear electric motors (3), the other end with transverse tube fixture (5) is connected; Described handle riser fixture (6) is arranged on frame (7); Described controller (1) is electrically connected to linear electric motors (3), and power sensor (4) is electrically connected to controller (1); Described linear electric motors (3), power sensor (4), transverse tube fixture (5) is formed to force application system, two parallel being arranged on frame (7) of force application systems.
When experiment starts, controller (1) drives linear electric motors (3) motion, linear electric motors (3) by power sensor (4) and the transverse tube fixture to being arranged on handlebar test specimen (8) imposed load of (6) between a transverse tube fixture (5) and handle riser fixture; The variation that power sensor (4) is exerted oneself according to the size detection of imposed load thrust, then convert electric signal to and be sent to controller (1); Controller (1), according to the signal of this signal and predetermined imposed load, is controlled the motion of linear electric motors (3); When imposed load reaches predetermined imposed load, controller (1) drives linear electric motors (3) drawback movement, carries out reverse imposed load; When reaching predetermined reverse imposed load, controller (1) drives linear electric motors (3) drawback movement again, carries out and so forth the handlebar torture test.
