Abstract
Provided is a bicycle front fork bending fatigue testing machine composed of a controller, a linear motor, a force transducer, a front fork standpipe clamp, a force application clamp and a frame. According to the testing machine, since a linear motor force application system is adopted, dynamic response performance is substantially improved, test frequency is improved, and at the same time, the testing machine is simple in structure and convenient for maintenance, and improves reliability of a control system while satisfying the test frequency.
Description
Affiliated technical field
The utility model relates to a kind of bicycle front fork fatigue bending machine, especially can in warranty test machine application of force precision, improve the frequency of imposed load.
Background technology
Among GB3565-2005 " bicycle safe " 27.3 " front fork torture test ", EN14764:2005 " the City and trekking Bicycles-Safety requirements and test methods " 4.9.6 " front fork-repeated bend test " to the front fork torture test except the alternate load of having stipulated to apply, stipulated that also maximum test frequency should be 25HZ.But at present the force application system of known front fork fatigue tester generally consists of by application of force cylinder or hydraulic cylinder, control system, power sensor; Because pneumatic or hydraulic pressing system is stressed and the restriction of cylinder diameter, its movement velocity is lower, generally the highlyest can only reach 3-5HZ, can't satisfy the requirement that maximum test frequency should be 25HZ.
Summary of the invention
In order to overcome the low problem of existing front fork fatigue bending machine force application system frequency, the utility model provides a kind of testing machine that satisfies maximum test frequency.This testing machine has improved the frequency of test when having guaranteed application of force precision.
The technical scheme that the utility model adopts is: consist of the bicycle front fork fatigue bending machine by controller, linear electric motors, power sensor, vertical tube of front fork anchor clamps, application of force anchor clamps, frame.Described linear electric motors are installed on frame, and the mover of linear electric motors is connected with a terminal tool of power sensor, and the other end of power sensor connects application of force anchor clamps; Described vertical tube of front fork anchor clamps are fixed on the frame, are used for installing tested front fork; Described controller is connected with linear electric motors, power sensor electrical respectively.
When controller drives the linear electric motors motion, the mover of linear electric motors by power sensor and application of force anchor clamps to being installed in the front fork test specimen imposed load between application of force anchor clamps and the vertical tube of front fork anchor clamps; Then the variation that the power sensor is exerted oneself according to the size detection of imposed load thrust converts electric signal to and is sent to controller, and controller is according to this signal and the predetermined load that applies, the motion of control linear electric motors; When reaching predetermined imposed load, controller drives the linear electric motors drawback movement, and the front fork test specimen is carried out reverse imposed load; When reaching predetermined reverse imposed load, controller drives again drawback movement of linear electric motors, and so forth, realizes that applying alternate load carries out the bicycle front fork repeated bend test.
The beneficial effects of the utility model are owing to adopted the linear electric motors force application system that the dynamic response performance of this testing machine is improved greatly, to have improved the frequency of imposed load; Native system is simple in structure simultaneously, has improved the reliability of control system.
