Test device and test method for horizontal impact of chair

Abstract

The invention discloses a test device and a test method for horizontal impact of a chair. The test device comprises a testing platform, a mounting bracket and a hammer swing component, wherein the testing platform is used for bearing the tested chair; the mounting bracket is fixed on the testing platform; the hammer swing component comprises a rotating shaft and an impact hammer; the rotating shaft is pivoted on the mounting bracket; the impact hammer is fixed on the rotating shaft and can swing in a preset angle range; the impact surface of the impact hammer is coated by a soft material; and the impact hammer is flush with a part to be tested of the tested chair when swinging to the lowest position. The test method comprises the following steps of: fixing the tested chair and adjusting the height of the impact hammer properly; repeatedly pulling up the impact hammer to a certain height and then freely swinging the impact hammer; impacting the part to be tested of the tested chair; if the tested chair deforms or cracks within a preset impact frequency, judging that the test is passed; and otherwise, judging that the test is not passed. By swinging the impact hammer within a certain angle, impact load in horizontal direction is applied to the part to be tested of the chair when the impact hammer is swung to the lowest position, and the strength in the horizontal direction of the chair can be checked after repeating the operation for many times.

Description

technical field [0001] The invention relates to the field of seat performance testing, in particular to a seat horizontal 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 research and development of corresponding test equipment is also backward. At present, there is no horizontal impact test device for this type of seat. Contents of the invention [0003] ...
