Embodiment
Please common reference Fig. 1 and Fig. 2, the better embodiment of vibration-testing apparatus of the present invention comprises a control volume 10, one connecting link 20, one pillar 30, one sliding bar 310, one support bar 40 and two suspenders 50, described control volume 10 is a box body, its inside is provided with a motor 110, one power supply 120 and a rotor 130, its outer setting has a switch 140, one speed regulator 150 and a counter 160, fix a slide rail 312 on the described pillar 30, the one side of one slide block 314 is slidingly installed on the described slide rail 312, another side is fixed on the described sliding bar 310, and each suspender 50 includes a neck 52.
Described pillar 30 is fixed in the top of described control volume 10, described slide rail 312 is used to make described sliding bar 310 to slide up and down along the direction of described slide rail 312, the top of described sliding bar 310 is connected in the midpoint of described support bar 40, one end of bottom and described connecting link 20 is rotationally connected, the edge of the other end of described connecting link 20 and described rotor 130 is rotationally connected, the rotating shaft of described motor 110 links to each other with the center of described rotor 130, be used to rotate described rotor 130, described two suspenders 50 are individually fixed in the both sides of described support bar 40, described neck 52 is designed to human body neck shape, be used to hang a Devices to test as a MP3, the duty of described Devices to test during with the real simulated human motion.Wherein, the quantity of described suspender 50 be one or two all can, when described vibration-testing apparatus comprises a suspender 50, can test a Devices to test, when described vibration-testing apparatus comprises two suspenders 50, can test two Devices to tests simultaneously.
Wherein, described sliding bar 310 is by being installed on the described pillar 30 that described slide rail 312 and slide block 314 slide up and down, it also can be slidingly installed on the described pillar 30 by other modes, such as: a groove (figure does not show) is set on described pillar 30, the one side of described slide block 314 is fixed in the middle part of described sliding bar 310, another side slides and is embedded in the described groove, can realize that described sliding bar 310 can slide by described relatively pillar 30.
Described motor 110 is controlled by described switch 140, speed regulator 150 and counter 160, and described power supply 120 links to each other with described motor 120, speed regulator 150 and counter 160 by described switch 140, is used to it that voltage is provided.The control end of described speed regulator 150 and counter 160 all links to each other with described motor 110, and described speed regulator 150 is used to regulate the rotating speed of described motor 110, and described counter 160 is used to set and write down the rotation number of turns of described motor 110.
Principle of work to described vibration-testing apparatus describes below.When opening described switch 140, after promptly connecting described power supply 120, described motor 110 promptly can drive described rotor 130 and rotate, described rotor 130 will slide up and down by the direction of the described sliding bar 316 of described connecting link 20 drives along described slide rail 312, thereby driving described support bar 40 moves up and down, two suspenders 50 that lay respectively at described support bar 40 both sides also move up and down thereupon together, described Devices to test is hung on the neck 52 of described suspender 50, can simulate described Devices to test and work in vibration environment, thereby detect its vibration resistance.
