Background technology
Damper test stand is one of key equipment in the delivery vehicle vibration damper production runes such as automobile, rolling stock.Up to now, the damper test stand of domestic research and development all is to adopt (referring to Chinese patent 95226272.X, 200820160048.9) of toggle as the sine excitation motion generator.In theory, toggle does not produce sinusoidal motion.
Toggle is owing to it is realized simply, load-bearing capacity is widely used in using as exciting agency in the damper test stand by force and than the characteristics of motion near sine mechanism.But the mechanism kinematic error of its generation is perplexing the measuring accuracy of damper test stand always, causes the load-position diagram distortion, has usually covered the defective of tested vibration damper." the damper test stand mechanism error is analyzed and indemnifying measure " literary composition that last Wang Tian profit of 2003 the 1st phases of LiaoNing technical faculty journal etc. is delivered, attempt to solve the mechanism kinematic error problem by the raw data of test macro collection is proofreaied and correct, it has not only increased software development cost because of computation process is complicated, more crucial is, and it can only reduce and can not eliminate described mechanism kinematic error.Also had some papers published and graduate degree paper studies in recent years in addition and solved the mechanism kinematic error problem by the raw data of test macro collection is proofreaied and correct.
Summary of the invention
The incredible problem of test result that causes in order to overcome can not the eliminating the mechanism kinematic error of existing damper test stand, the utility model provide a kind of can eliminate fully that aforesaid mechanism kinematic error, mechanism's life-span are long, the damper test stand of manufacturing and employing single-rail formula sine transmission device easy to maintenance.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind ofly adopt the vehicle shock absorber test-bed of single-rail formula sine transmission device, comprise support, on the described support guide pillar is installed, on the described guide pillar crossbeam is installed, described crossbeam is provided with anchor clamps, crank disc is installed in the described support, crank axle, gearing and motor, the rotating shaft of described crank disc is connected with gearing, described gearing is connected with motor, described crank axle is installed on the crank disc, the axle center of described crank axle is positioned at the eccentric position of described crank disc, the described vehicle shock absorber test-bed sine transmission device that also comprises, described sine transmission device comprises master slider and secondary slide block, an end of described secondary slide block has bearing saddle bore, be provided with bearing between described bearing saddle bore and the crank axle, the other end of described secondary slide block can be connected slidingly with master slider;
Described master slider is provided with longitudinal rail, and described support is provided with the longitudinal sliding block group, and described longitudinal rail can slide up and down to be sleeved in the longitudinal sliding block group;
Described master slider is provided with last anchor clamps on the crossbeam and cooperates in order to the lower clamp of piece fixture to be installed.
Further, described secondary slide block is fixedlyed connected with transverse slider, and described cross slide way is fixedlyed connected with master slider, and described transverse slider can be sleeved on the cross slide way slidingly.
Or: described secondary slide block is fixedlyed connected with cross slide way, and described transverse slider is fixedlyed connected with master slider, and described cross slide way can be sleeved on the transverse slider slidingly.
Technical conceive of the present utility model is: the driving crank disc that rotatablely moves of motor output is done uniform rotation, offset crank shoft on the crank disc drives secondary slide block by bearing and does translation, secondary slide block drives master slider by cross rail and does straight reciprocating motion up and down, the final end of the drive of the anchor clamps on master slider vibration damper of realizing is done straight reciprocating motion up and down, and the straight reciprocating motion up and down of described vibration damper one end launches to be a sinusoidal curve on time coordinate.
Technical conceive of the present invention also comprises: the master slider of sine transmission device is extended a sufficiently high position by a pillar and be connected with last anchor clamps, lower position at support is provided with lower clamp, sine excitation motion by last anchor clamps also can realize the test of ride-control; In addition, sine transmission device can be arranged on the top of a sufficiently high support, the lower end of master slider is provided with anchor clamps, at the lower position of support lower clamp is set, and the sine excitation motion by last anchor clamps also can realize the test of ride-control; In addition, upper and lower two cover sine transmission devices can also be set in a sufficiently high support, by the sine excitation motion of upper and lower anchor clamps, realize the two moving torture test of ride-control respectively.
Designed and a kind ofly can satisfy the single-rail formula sine transmission device that damper test stand sine excitation motion requires, can eliminate the mechanism kinematic error of prior art fully, and had mechanism's life-span length, low cost of manufacture, advantage easy to maintenance.
The beneficial effects of the utility model mainly show: the mechanism kinematic error that can eliminate existing damper test stand exciting agency fully, can produce high-precision sine excitation motion, properties of product quality testing and the experimental technique level that promotes China's ride-control industry is significant.
