The invention discloses a heavy vehicle mass and mass center detection device. The existing devices mainly use side weighing methods, the number of sensors is small, and the devices have certain limitations. The detection device comprises a foundation pit, a four-degree-of-freedom (4DOF) platform, pressure sensors, a vehicle to be detected and a horizontal table board; the 4DOF platform is arranged in a foundation, and a plurality of pressure sensors are arranged on the upper surface of an upper cylindrical portion of an upper platform of the 4DOF platform from center to periphery along an Archimedes spiral; and the horizontal table board is covered on the pressure sensors, and the vehicle to be detected is arranged on the horizontal table board. The 4DOF platform can rotate along an X axis, a Y axis and a Z axis, and the pressure sensors in the device work out the mass and the position of the mass center of the vehicle rapidly according to different positions and pressure gained in the detection during rotating movement. According to the detection device, the measurement accuracy of the sensors is guaranteed by arrangement optimization of the sensors, and the measured mass and the position of the mass center are more accurate and reliable.
Description
technical field [0001] The invention belongs to the technical field of mechanical device detection, and in particular relates to a heavy-duty vehicle mass centroid detection device. Background technique [0002] For heavy-duty vehicles operating under special road conditions and working conditions, their roll stability and handling stability are directly affected by the height of the vehicle's center of mass. Therefore, the coordinate position of the center of mass has a great influence on the handling stability and safety of the heavy-duty vehicle. Therefore, the coordinate position of the center of mass of the heavy-duty vehicle has high requirements. [0003] Although in the design of the vehicle, through computer software simulation and calculation of mechanical properties, the mass of the vehicle and the position of the center of mass can be calculated. However, compared with heavy-duty vehicles, the large number of parts and complex shapes, coupled with the inhomogene...
