Abstract

The work aims to reduce the use of materials and production cost on the basis of ensuring mechanical properties by studying the law of influence of corrugated parameters of corrugated board on mechanical properties. In the range of national standard, the experimental values of the width, height and radius of the corrugated board were selected uniformly. The single factor experiment was designed to deduce the compression ratio coefficient of the core paper. The finite element method was used for quasi-static compression test to obtain the edge crush resistance of corrugated board and the ratio of edge crush resistance to compression ratio coefficient. The compression ratio coefficient gradually decreased with the increase of the width of the corrugated unit and the radius of the corrugated peak, and increased with the increase of the height of the corrugated unit. The width of the corrugated unit had the largest influence, followed by the height of the corrugated unit and then the radius of the corrugated peak. The edge crush resistance gradually decreased with the increase of the width of the corrugated unit, and increased with the increase of the height of the corrugated unit. The edge crush resistance fluctuated greatly with the increase of the radius of the corrugated peak. The edge crush resistance was the largest at 1.3 mm. Under the condition of single factor variation, the ratio of edge crush resistance to compression ratio coefficient was the largest when the width of the corrugated unit was 3.4 mm, the height of the corrugated unit was 3.75 mm, and the radius of the corrugated peak was 1.3 mm. The corrugated geometric parameters have obvious influence on the edge crush resistance and compression ratio coefficient of corrugated board; therefore, choosing the appropriate combination of geometric parameters can reduce the use of materials on the basis of ensuring the edge crush resistance.
