Stability parameter test board for automobile

Abstract

The invention discloses a stability parameter test board for an automobile and belongs to the technical field of measurement. The test board is used for integrally testing a quality parameter, a mass center position parameter and an anti-rollover angle parameter of the automobile. The stability parameter test board consists of a measuring table board, four platform scales, a table board pillar, a foundation, three hydraulic cylinders, an inclination angle measuring device, hydraulic sensors, a pumping station and a computer, wherein the platform scales are arranged on the measuring table board and supported by a weighing sensor; supporting points of the table board pillar are distributed in a form of rectangular top points; the foundation is used for supporting the pillar and the table board; the three hydraulic cylinders are arranged between the table board and the foundation and can make the table board incline longitudinally or laterally; the inclination angle measuring device is fixed on the table board; the hydraulic sensors are arranged at upper and lower cavity positions of two hydraulic cylinders which make the table board incline longitudinally; the pumping station is connected with the hydraulic cylinders; and the computer is used for acquiring data of the weighing sensor, oil pressures of the hydraulic cylinders and the inclination angle of the table board and performing an operation. The table board has the advantage that: compared with a conventional test device, the device can complete tests on the total mass, the axle load, the wheel load, the mass center position, the anti-overturn angle and the like of the automobile, so the test workload and the test cost of the parameter test are lowered.

Description

technical field [0001] The invention belongs to the technical field of measurement in physics, and in particular relates to test equipment and a test method for automobile axle load, wheel load, total vehicle mass, centroid height, anti-rollover angle. Background technique [0002] The axle load, wheel load, total vehicle mass, center of mass height, anti-rollover angle and other parameters of the vehicle are important parameters for evaluating the overall performance of the vehicle, and are also important basic data for chassis control systems such as automotive electronic stability control. Therefore, parameters such as automobile axle load, wheel load, total vehicle mass, height of center of mass, and anti-rollover angle have always been important fields of automobile parameter testing technology, but at present, the measurement of these parameters is mostly completed by a single special test bench, resulting in test A lot of work and a lot of cost. Developing an all-in-...
