Изобретение относитс к испытательной технике, а именно к копрам дл ударных испытаний материалов.The invention relates to a testing technique, namely, frames for impact testing of materials.
Известен копер дл ударных испытаний , содер ха1дий основание,подвешенный к основанию ма тник и приспособление дл установки испытуемого образЦа II .A well-known impact test head, containing a base suspended from a base, and a device for mounting the test specimen II.
Недостатком данного копра вл етс то, что испытани на нем могут прово- ,Q дитьс только при низких скорост х ударного нагружени .The disadvantage of this copra is that tests on it can be conducted, Q, only at low rates of shock loading.
Наиболее близким к предлагаемому по технической сущности вл етс копер is дл ударных испытаний, содерхащий основание , подвешенный к основанию ма тник , приспособление дл установки испытуемого образца, ротор с приводом его пра1 ени и муфту сцеплени дл 20 св зи ротора с ма тником. Ротор выполнен в виде массивного уравновешенного маховика. Копер работает следующим образом. Перед испытанием ма тник фик;The closest to the proposed technical entity is a pile driver for shock testing, containing a base, a holder suspended from the base, a device for mounting the test specimen, a rotor with its drive and a coupling for connecting the rotor with the dial. The rotor is designed as a massive, balanced flywheel. Koper works as follows. Before the test of a tomb;
сируетс в верхнем поло)хении. Ротор разгон етс до требуемой скорости, а освобождаемый ма тник с помощью муфг ты сцеплени подключаетс к ротору, кото1)ый осуществл ет дополнительный разгон ма тника до удара. Непосредственно перед ударом ротор отключаетс 2 .It is located in the upper cavity. The rotor is accelerated to the required speed, and the freed tee is connected to the rotor by means of the clutch, which carries out additional acceleration of the tee before impact. Immediately before impact, the rotor is shut off 2.
Недостатком указанного копра вл етс наличие больших ударных нагрузок при включении муЛты сцеплени , что обуславливает большую металлоемкость конструкции. Если же разгон ть ротор вместе с ма тником, то на всю конструкцию действует центробежна сила от неуравновешенного ма тника.The disadvantage of this copra is the presence of large shock loads when the coupling clutch is engaged, which causes a large metal intensity of the structure. If, however, the rotor is accelerated along with the tambour, then the centrifugal force from the unbalanced tiller acts on the whole structure.
Цель изобретени - уменьшение металлоемкости конструкции путем снижени величины ударных нагрузок.The purpose of the invention is to reduce the metal structure by reducing the magnitude of the shock loads.
