| Zusammenfassung: | The utility model relates to a speed-adjustable ejection device used in crash tests (see the attached figure), which belongs to the fields of strength dynamic tests, collision simulation experiments and other relative technology. The ejection device mainly comprises two parts, namely a high-speed ejection drive part and an ejection recovery drive part, wherein the high-speed ejection drive part is formed by connecting a gas storage tank (1), a control valve group (2) and an ejection cylinder (3) serially in series; the ejection recovery drive part consists of a control valve (5) and a recovery cylinder (4); and the ejection cylinder and the recovery cylinder are conveniently and flexibly connected through magnetic attraction. The ejection device has the advantages of simple operation, simple and compact structure, higher simulation, and better testing and adjusting performances. |
