Embodiment Construction

[0028] figure 1 , 2 In , the collider, box and counterweight components are combined together, and can be suspended at the lifting point c by four steel wire ropes d to form a parallel pendulum. For the convenience of description, this paper sets the collision direction as the front, and the other left , Right, and Back are all based on this. The collision center point b is located in the middle of the protruding part of the front end, and this point is the initial contact point with the test vehicle during the test. The collision direction a is the movement direction of the collider, which is parallel to the horizontal plane and perpendicular to the front end of the collider. A straight line passing through the collision center point and parallel to the collision direction is called the collision centerline.

Abstract

The invention relates to a weight box with adjustable mass and maintenance of the position of a mass center. The weight box comprises a box body, the upper surface of the box body is open so that different balancing weights are conveniently replaced, balancing weight components are arranged in the box body, and comprise narrow supporting plates, eccentric balancing weights, hollow balancing weightgroups and/or solid balancing weights; the box body is formed by connecting a left side plate, a right side plate, a bottom plate and a rear baffle through screws, the front surface of the box body is connected with a collision device, the rear baffle of the box body is provided with a threaded rod for compressing the balancing weight components in the box body, and the upper portions of the leftside plate and the right side plate of the box body are respectively provided with hanging plates. The box body structure is used as the counterweight, and the counterweight mass is adjusted by adopting a mode of replacing the hollow counterweight and the solid counterweight. Compared to a traditional mode, the weight box with the adjustable mass and maintenance of the position of the mass centerhas the following advantages in that: 1. the mass is adjustable, and can ensure the adjusting precision, 2, when the mass is adjusted, the position of the mass center is kept unchanged in the up-downdirection and the left-right direction, 3, the structure is firm and fast, and the rigidity can be ensured, 4, the counterweight adjustment is convenient and fast to operate, and 5, the weight box has expansibility.

Description

technical field [0001] The invention is applied in the field of passive safety of automobiles. As a counterweight box, it is applied to impact tests of front and rear end protection devices of automobiles, and can also be used in other impact tests. Background technique [0002] GB17354_1998 "Automobile Front and Rear End Protection Devices" and ECE R42 "Unified Regulations on the Approval of Vehicle Front and Rear End Protection Devices (Bumpers, etc.)" stipulate a test method. Collide with the front and rear end protection devices (i.e. bumpers) of the test vehicle at 4km / h. The effective mass of the collision is equal to the "vehicle curb weight" of the test vehicle. The collider can be fixed on a small car (movable barrier). It can also be fixed on the pendulum as part of the pendulum. [0003] The effective mass of the collision is equal to the "whole vehicle curb weight" of the test vehicle. For test vehicles of different qualities, the collider should be weighted wit...
