Problems solved by technology

The center of mass and mass distribution of the sandbags are very different from those of the human body, the test results have large errors, and a large number of sandbags are not easy to carry, which increases the workload of the test personnel
Using real people as a vehicle performance test has certain risks, and it increases the number of testers and increases the cost of the test. At the same time, due to the influence of the tester's own weight, when multiple testers are used for the test, the consistency of the test results is poor

Embodiment Construction

[0028] Such as figure 1 As shown, a water-based human body model includes a head water bag 3, a trunk water bag 6, a thigh water bag 7, and a calf water bag 8 made of PVC material, and the head water bag 3 and the trunk water bag 6 are , the thigh water bag 7 and the calf water bag 8 are split structures, and between the head water bag 3 and the trunk water bag 6, between the trunk water bag 6 and the thigh water bag 7, and between the thigh water bag 7 and the calf water bag 8 There are multiple groups of combined valves 5 respectively, and two groups are taken as an example in this embodiment. Such as figure 2 As shown, the combined valve 5 is composed of a valve I501 and a valve II502 connected by flanges, and a gasket is provided between the valve I501 and the valve II502. On the head water bag 3, the trunk water bag 6, the thigh water bag 7, and the calf water bag 8, there are respectively center-of-mass adjustment clips 4, and the center-of-mass adjustment clip 4 cons...

Abstract

The invention relates to a water-base manikin which comprises a head water bag, a trunk water bag, a thigh water bag and a shank water bag, wherein all the water bags are provided with split structures and are made of soft transparent materials; multiple sets of combined valves are respectively arranged between the water bags; a mass center adjusting clamp is arranged on each of the water bag. An adjusting method for mass and gravity center of the water-base manikin comprises the steps of: confirming sizes of the water bags; manufacturing the water bags; adjusting the weight of the water bags; adjusting the mass center; and dewatering. A true person is replaced by the water-base manikin, so that the number of test personnel is reduced, the test risk is reduced, and the test cost is saved. After the mass and the mass center position are adjusted, signs are marked on the water bags and the mass center adjusting clamps, so that a water injection rate and a distance between loops of the mass center adjusting clamps are confirmed according to the signs during the test process and the consistency of the test data is excellent. The water bags are split, thereby being convenient and labor-saving in carrying.

Description

technical field [0001] The invention relates to a counterweight used in an automobile performance test, in particular to a water-based human body model and a method for adjusting its mass and center of gravity. Background technique [0002] Automobile performance test is a means of judging various technical parameters of automobiles. Some car performance tests need to be carried out when the car is half-loaded or fully loaded, which requires the use of counterweights. The counterweight used in the current automobile performance test is generally a sandbag or a real person. The center of mass and mass distribution of the sandbags are very different from those of the human body, the test results have large errors, and a large number of sandbags are not easy to carry, which increases the workload of the test personnel. Using real people as a vehicle performance test has certain risks, and it increases the number of testers and increases the cost of the test. At the same time,...
