A kind of dynamic measuring device and measuring method of mass and centroid position of multi-axle vehicle

Abstract

The invention relates to a device and a method for dynamically measuring the mass and mass center locations of multi-axis vehicles, and belongs to the field of technologies for dynamically measuring the mass and mass center locations of vehicles. The device comprises load sensors, wheel speed sensors, an acceleration sensor, a vehicle body attitude sensor and a computation processor. The load sensors, the wheel speed sensors, the acceleration sensor and the vehicle body attitude sensor are respectively connected with the computation processor; the computation processor comprises a single chip microcomputer, a signal acquisition module, an output module, an alarm module, a program uploading / downloading module, a power supply module and communication interfaces, and the communication interfaces are respectively connected with the various sensors. The device and the method have the advantages that the vehicle mass and mass center location measurement ranges of the device are not only limited on two-axis four-wheel vehicles, and the device and the method can be applied to the multi-axis vehicles; the mass and the mass center locations of the vehicles can be dynamically measured by the device, accurate dynamic data can be provided for controlling the vehicles, and accordingly active control effects of the vehicles can be obviously improved.

Description

technical field [0001] The invention relates to a dynamic measurement device and method for measuring the mass and centroid position of a multi-axis vehicle, belonging to the technical field of dynamic measurement of the mass and centroid position of vehicles. Background technique [0002] At present, the methods for measuring the position of the center of mass of automobiles at home and abroad mainly include: weight response method, swing method, suspension method, platform support reaction force method and zero position method. However, all of the above are measurement methods when the vehicle is in a static state. When the vehicle is in motion, there is a certain deviation between the actual position of the center of mass and the measured value, and these measurement methods are mostly aimed at small two-axle (four-wheel) vehicles. For vehicles with spring suspension systems, especially for large multi-axle vehicles with fluid loads, such as fire trucks, concrete mixer tr...
