Abstract

The invention discloses a device and method for calibrating a stay wire displacement sensor. The calibration device includes a bottom plate and gauge blocks. A sensor setting position used for placing the stay wire displacement sensor is arranged on the bottom plate, and the gauge blocks are arranged on the bottom plate and are located at one side of the sensor setting position. The device for calibrating the stay wire displacement sensor is simple in structure and convenient to install, and can be used repeatedly, thereby improving calibration efficiency.

Description

technical field [0001] The invention belongs to the technical field of automobile product testing, in particular, the invention relates to a calibration device and a calibration method for a cable displacement sensor. Background technique [0002] In the process of automobile crash safety development test, the effective collapse of the pipe string can reduce the damage value of the chest and abdomen of the dummy. In order to check the collapse and energy absorption of the pipe string, it is necessary to use the cable displacement sensor to detect the dynamic collapse displacement of the pipe string. Quantity, to provide effective test data as a reference for later design. At the same time, in the seat belt dynamic test, both ECER16 and GB14166 require the measurement of the displacement of the dummy's chest and pelvis. It is necessary to use the cable displacement sensor to detect whether the displacement of the dummy's chest and pelvis meet the standard requirements during ...
