Problems solved by technology
However, in this measurement technique, only the torsion angle of the longitudinal beam itself can be measured, and a longer torsion bar is required to ensure the measurement accuracy. In this way, it cannot be implemented due to the limitation of the arrangement of the longitudinal beam in actual measurement. Not strong

Embodiment Construction
[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0034] Such as Figure 1 to Figure 4 As shown, the present invention provides a system and method for measuring the torsion angle of a vehicle frame, which is different from the way in the prior art that only uses straight rods to measure the torsion angle of the longitudinal beam. As the concept of the present invention, the measurement method provided by the present invention It includes: first installing the torsion bar 1 with an L-shaped bar on the vehicle frame, so that the two bar sections of the L-shaped bar extend along the longitudinal beam and the cross beam of the vehicle frame respectively, that is, the two bar sections are basically vertical, and T...

The invention discloses a measuring system and method of a vehicle frame torsion angle. The measuring system comprises a torsion rod (1) and an angle detection system (2). The torsion rod is L-shaped. Two rod segments of the L-shaped rod are respectively installed on a longitudinal beam and a cross beam of a vehicle frame. The torsion rod is provided with a displacement end and a measuring end. The rod segment provided with the displacement end can at least installed on the vehicle frame in an axial moving manner. The rod segment provided with the measuring end can at least installed on the vehicle frame in a rotatable manner. The angle detection system is used for detecting a relative rotation angle of the measuring end. According to the invention, the structure of the vehicle frame itself is ingeniously utilized, and the L-shaped rod is used as the torsion rod, so that the torsion rod can be conveniently arranged in the region in need of torsion angle measurement, the measurement of the torsion angles of various vehicles is realized, and the measurement precision is ensured; in addition, the obtained vehicle torsion angle can also be compared with a CAE analysis result, and the vehicle torsion angle is evaluated scientifically and objectively, so that the practicality and the popularization value are relatively high.
Description
technical field [0001] The invention relates to the field of vehicle frame torsion angle measurement in vehicle performance testing, in particular to a system and method for measuring the torsion angle of a vehicle frame. Background technique [0002] In the field of automobile performance testing, it is necessary to measure the torsion angle of the frame and evaluate the influence of the road on the overall structural deformation of the frame according to the variation of the torsion angle and compare the influence of the local structure change of the frame on the overall torsion angle. Among them, the frame is the core component of the car, and its quality and performance directly affect all performance indicators of the vehicle. The torsion angle of the frame is a key indicator of the assessment. The rigidity required by the frame is actually built on the deformation resistance of the frame, that is, the frame’s resistance to bending or twisting due to external forces. O...
