Embodiment Construction

[0028] The body rigidity test bench consists of two parts:

[0029] The first part of the twisting device, see Figure 1

[0030] 1) Install a pair of bearing housings 2 on the upper end of the rotating beam pillar 1, and the rotating shaft and bearing of the rotating beam 8 are respectively installed in the bearing housing 2. At this time, the rotating mechanism is composed of the rotating beam pillar 1, bearing housing 2 and rotating beam 8. The beam can rotate with the bearing seat 2 as the fulcrum when it is subjected to an external force.

[0031] 2) Three slider mechanisms are installed on the rotating beam, and the slider mechanism is composed of a slider 11 and a slider locking block 12 . When the locking mechanism is in the unlocked state, the locking mechanism can move freely along the axis of the rotating beam, otherwise it is fixed and locked.

[0032] 3) The four-bar hinge mechanism consists of a gapless joint bearing seat 3, a joint bearing 4, a connecting rod 5...

Abstract

A rigidity test bed of automobile body consists of torsional unit formed by rotary mechanism, sliding block mechanism and four-rod hinge mechanism; and fixing unit formed by fixing beam, fixing beam support, sliding block mechanism, fixed support base, link, oscillating bearing and seamless connection clamp.

Description

technical field [0001] The invention relates to a test device used for the bending rigidity and torsional rigidity test of the vehicle body in the development of automobile products. Background technique [0002] With the demand for localization of automobile development, whether the rigid technical indicators of body structure design can meet the design requirements, the only way to judge it is to draw conclusions through rigidity tests. The body rigidity test bench is an indispensable test equipment in the development of automobile products. The results of the test data can reflect the defects or weak points in the design in time, and provide a basis for design modification to ensure the design quality of the product. Shorten product development cycles. [0003] Due to the relatively specific scope of application of the body rigidity test bench, the body rigidity test bench of each user unit is a non-standard test bench designed and manufactured by itself. In the torsion ...
