The rear side of frame.Multiple actuator coordinate control systems to act on carrier frame, and the motion between different actuator be can
With independent control, each actuator can be indulged basket-hanging carrier frame in testing stand by the less realization that is used as power
To, it is vertical, horizontal, nod, reverse and sidewinder six degree of freedom exciting, so as to by being stepped in Walk Simulation wheel roller, directive wheel
Tread roller 21 is completed to single the longitudinal, vertical of straddle-type single shaft single rail bogie, transverse direction, point in surface roller 18, steady wheel
Head, reverse and sidewinder six degree of freedom exciting.It can realize by relatively low into the original mould for completing road pavement actual conditions
Intend, realize the simulation to monorail track travelling wheel orbital plane, steady wheel orbital plane and directive wheel orbital plane irregularity.
Counterweight car is placed with the top of bogie.The present invention is directed to six pot one of straddle-type single shaft single-track vehicle bogie
Drum-type entirety six degree of freedom exciting trolley coach bogie test chassis reloads problem, there is provided one kind simulation straddle-type single shaft
The counterweight car of single rail bogie car weight and moment of inertia.Four fillet welding for simulating half car experiment vehicle frame counterweight car have drawing pull bar
Mechanism car body fixed seat installing plate 29, middle two side bottoms are welded with counterweight car and hourglass upper bracket of the spring connecting plate 30, centre two
Weld a pair of ball bearing installation axles and bearing installing plate 31 in side.Cloud rail car bogie drawing pull bar mechanism 24 is bolted peace
On counterweight car drawing pull bar mechanism car body fixed seat installing plate 29.The hourglass spring of hourglass upper bracket of the spring and counterweight car
Upper bracket connecting plate is connected by screw bolts, so as to realize that half car of simulation experiment vehicle frame counterweight car and straddle-type single shaft single track turn to
The annexation of frame.Simulate half car experiment vehicle frame counterweight car and pass through four drawing pull bar mechanism car body fixed seats and hourglass spring
Upper bracket and straddle-type single shaft single rail bogie are connected, and straddle-type list is simulated by placing certain amount 25Kg counterweights
The actual body quality born of axle single rail bogie.Simulate be welded with all counterweight groove of half car experiment vehicle frame counterweight car it is some
Baffle plate, prevent that simulate half car experiment vehicle frame counterweight car produces relative displacement with counterweight in bogie motion process, causes inertia force
The fluctuation of square.A number of 25Kg counterweights are placed on different slots position, so as to simulate the quality of different vehicle bodies and inertia
Torque.
Because testing stand is to be directed to single single shaft straddle-type monorail bogie to do experiment, by simulation half car experiment vehicle frame weight
Code car is connected with bogie, therefore simulation half car experiment vehicle frame counterweight car can follow straddle-type single shaft list during experiment
Rail bogie makes a little first-class six-freedom motion.This motion can not possibly occur in actual vehicle running, therefore need
Design counterweight car longitudinally, laterally constrain truss assembly be arranged on counterweight car outside, guarantee test vehicle frame counterweight car have and
The identical free degree in the reality vehicle operation of border.There are two ball bearing installation axles up and down counterweight car both sides, side, and side has
Three ball bearing installation axles of upper, middle and lower.Four ball bearing installation axles are connected double with four SKG60ES welded types respectively by ball pivot
The longitudinally connected bar assembly of oscillating bearing is connected, the longitudinally connected equal position of bar assembly of four having a double meaning bearings of SKG60ES welded types
In longitudinal direction, on horizontal direction 32, the side of counterweight car is connected a SKG60ES welded type doublejointed by ball pivot
The longitudinally connected bar assembly of bearing is transversely mounted in the ball bearing installation axle and bearing installation board assembly 31 of counterweight car, 4
Longitudinal longitudinally connected bar assembly of the having a double meaning bearings of SKG60ES welded types and 1 horizontal having a double meaning bearings of SKG60ES welded types
The other end of longitudinally connected bar assembly is connected by ball pivot to be connected with ball-joint bearing 38, and SA60ES ball-joints bearing 38 is logical
Cross bolt connection longitudinally, laterally to constrain on the connecting cleat on truss assembly installed in counterweight car, SKG60ES welded types are double
The both ends of the longitudinally connected bar assembly of oscillating bearing are connected using ball pivot.Such layout constraints simulate half car experiment vehicle frame
The relative motion of counterweight car and straddle-type single shaft single rail bogie, it ensure that constraint simulation half car experiment vehicle frame counterweight car is relative
