Technical Field

The invention belongs to the technical field of automobile crash tests, and particularly relates to a tool for batch positioning of mark points before a crash test.

Background

In the preparation process of the front collision and side collision test, point marks need to be drawn on key structure areas, three-dimensional coordinates of mark points are measured before and after the test, and deformation of the key structure is calculated according to coordinate difference. The number of measurement mark points before the test is large and certain interval requirements are met, and a large amount of time and manpower are consumed to finish the point drawing work in the test preparation process. In the process of preparing a pedestrian protection head collision test, all collision points need to be marked on the hood according to the test requirements for selection, and multiple tests need to prepare multiple hoods, and mark corresponding collision points on each hood.
