Abstract

The invention discloses a measurement system for a quality mass center of an instrument panel assembly and a measurement method. The measurement system for the quality mass center of the instrument panel assembly consists of a measurement device and a data collection control assembly. The measurement device is constituted by measurement units. The measurement unit consists of an instrument panel support mechanism, an elevating mechanism and a bottom support mechanism. A sliding block on the top of the support mechanism can perform two-direction sliding with two free degrees. The elevating mechanism can be vertically adjusted. The bottom support mechanism can perform two-direction sliding. An instrument panel to be measured is installed on the instrument support mechanism, the elevating mechanism and the bottom support mechanism are adjusted, measurement and collection are performed through the data collection control assembly, and the mass center of the instrument panel is obtained bycalculation. The measurement method adopts four point method, and can realize one time clamping to realize measurement on quality and mass center of the instrument panel to be measured. The measurement system and measurement method not only realize measurement on three-dimensional instrument, but realize real-time monitoring and calculate a verification testing result and an effective measurementaccuracy.

Description

technical field [0001] The invention belongs to the technical field of auto parts testing, in particular to an instrument panel assembly mass centroid measurement system and a measurement method thereof. Background technique [0002] The center of mass is the center of mass of an object, which coincides with the center of gravity in a uniform gravitational field. Mass and centroid are important basic characteristic parameters in the field of automotive engineering, and are indispensable input boundary conditions in CAE simulation analysis, which have important influences in actual use. [0003] The automobile instrument panel assembly has the characteristics of large size, irregular shape, and relatively small mass. There is a large error between the mass centroid parameters obtained through theoretical calculations and practical applications. The existing mass and center of mass measurement technology for automobile dashboards is only completed by a fixed weighing device, ...
