When needing to carry out wheel load detection, wheel passes through four contact points of weighing sensor to the active force of weighing unit 2
It is changed into electric signal, after the processing that electric signal passes through hardware system, the weighing data of vehicle is transferred to display screen, completes logarithm
According to acquisition.
When needing to carry out centroid detection, each weighing unit 2 can be recorded by inputting direction of traffic and wheelbase information, weighing sensor
Normal load and full payload signal and signal is fed back into system, network analysis judge the load condition of weighing unit 2, mass center away from
With a distance from first axle and mass center deviates central axis and determines that mass center in the position of X, Y plane, is tested into height of center of mass after
When interface, controller control hydraulic system makes one or more weighing unit 2 rise to setting stroke, automated system operation mass center
High measure program, to obtain the position of mass center in z-direction.
When needing to carry out chassis torsion test, controller, which can control hydraulic system according to test requirements document, makes front and rear
At least two weighing units 2 in weighing unit 2 complete lifting, and move to setting stroke, utilize weighing sensor and displacement detecting
Device acquire respectively wheel by force information and displacement information, then by the way that after the processing of hardware system, data are shown external
On display screen, the measurement to vehicle frame torque is completed.
In short, vehicle centroid detection platform 100 according to an embodiment of the present invention, by be arranged multiple weighing units 2 and
Corresponding multiple elevating rams 3, and lifted or combined artificial lift using the independent of each weighing unit 2, to can be achieved at the same time pair
The measurement of vehicle wheel load, mass center and vehicle frame torque.
