Chair vertical impact test device and test method

Abstract

The invention discloses a chair vertical impact test device and a test method. The test device comprises a test board, a mounting support, an impact part and a lifting mechanism, wherein the test board includes a base and a supporting seat fixed on the base, and the supporting seat bears a test seat. The mounting support comprises a left vertical column, a right vertical column and a beam which is arranged at the top end of the left and the right vertical columns. The left and the right vertical columns are fixed on the base. The impact part is lifted to the prearranged suspension height of the beam by the lifting mechanism in a first condition and is freely released to impact the part to be tested of the test chair in a second condition. By means of the test method, the impact part is repeatedly lifted to the prearranged height to drop freely and impact the part to be tested of the test chair. If the test chair deforms or is fractured within the prearranged impact times, the chair is determined to pass the test; otherwise, the chair fails the test. According to the test device and the test method, the impact part drops freely from the suspension state, accordingly an impact load vertical to the part to be tested of the test chair is imposed, and the strength of the test chair in a vertical direction can be tested after repeating a plurality of tests.

Description

technical field [0001] The invention relates to the field of seat performance testing, in particular to a seat vertical impact test device and a test method for strength testing of plastic seats. Background technique [0002] Currently, there is a lack of standardized performance testing methods for plastic seats fixed on steps in sports venues. The European region has proposed to establish a unified parameter standard and corresponding measurement method, but it has not been able to reach a unified consensus. Some countries in other regions have experience in establishing corresponding standards, but it is difficult to form a unified standard, which in turn affects the import and export trade of such products. However, due to the non-uniformity of test standards and test methods, the development of corresponding test equipment is also backward. At present, there is no vertical impact test device for this type of seat. Contents of the invention [0003] In view of this, ...
