Abstract

A portable type car outer cover component deforming stiffness test device which includes a carline and a beam of the first slid fixed on the cowl carline and it can drive the first slid moving up and down by the first screw stem so further drive the beam moving up and down and the second screw stem drives the second slid moving left and right; the load-on measuring mechanism connects with the second slid by the driving adjustment mechanism which includes the body, the electric engine set in it, the gear driving equipment, lead screw component, load-on light bar, and the displacement sensor, the pressure sensor. The test device of invention adopts the assemblage frame mechanism and it can adjust randomly for the experimental point of different cover component in the three-dimension space and it can measure the stiffness of cover component through applying the normal load to the experimental point also gives the load-displacement curve of the experimental point according it to judge the ability of outer cover component deforming stiffness, stability, and portable selection material of the car outer cover component.

Description

technical field [0001] The invention relates to a mechanical property tester, in particular to a test device for deformation stiffness of an automobile outer cover. Background technique [0002] With the development of the car industry, users have higher and higher requirements for the manufacture of car bodies, and the performance of parts after stamping has attracted increasing attention. One of them is the rigidity of car panels. The deformation stiffness test is specially designed for the formed car parts. A special test method for stiffness evaluation (body outer cover), the test results can reflect the ability of body parts to resist deformation and maintain shape stability when subjected to external loads (or external energy). A new model abroad is in the process of development and trial production , It often needs to go through a lot of tests to evaluate the rigidity of the cover. For example, the design department of the French Renault Motor Company requires that th...
