下面结合附图举例对本发明做更详细地描述：The present invention is described in more detail below in conjunction with accompanying drawing example:
结合图1～3，金属底座1、金属连杆2、金属扣环3、橡胶块4组成受冲击装置。1-3, the metal base 1, the metal connecting rod 2, the metal buckle 3, and the rubber block 4 form the impact device.
铝块5、密封圈6、金属底座7、空腔8、气流通道9、阀门10和弹簧11组成吸能装置。Aluminum block 5, sealing ring 6, metal base 7, cavity 8, air flow channel 9, valve 10 and spring 11 form an energy absorbing device.
受冲击芯体橡胶块4装配在金属底座1空腔2内。利用金属扣环3限制芯体橡胶块4反弹时冲出金属底座1而发生危险。The impacted core rubber block 4 is assembled in the cavity 2 of the metal base 1 . The metal buckle 3 is used to limit the core rubber block 4 from rushing out of the metal base 1 and causing danger when rebounding.
受冲击芯体橡胶块4通过金属连杆与吸能装置中铝块5相连，通过连杆将冲击能量传递到吸能装置。The impacted core rubber block 4 is connected with the aluminum block 5 in the energy-absorbing device through a metal connecting rod, and the impact energy is transmitted to the energy-absorbing device through the connecting rod.
吸能装置中的芯体装配在在金属底座7空腔内，芯体包括铝块5、两个密封圈6和金属弹簧11。金属底座7上装有控制气流大小的阀门10，通过调节气流出口量的大小，从而实现该装置的阻尼大小，阀门10通过通气孔9与金属空腔8连通。The core body in the energy-absorbing device is assembled in the cavity of the metal base 7 , and the core body includes an aluminum block 5 , two sealing rings 6 and a metal spring 11 . The metal base 7 is equipped with a valve 10 to control the size of the air flow. By adjusting the size of the air outlet, the damping of the device is realized. The valve 10 communicates with the metal cavity 8 through the air hole 9 .
当霍普金森压杆动态测试系统的透射杆冲击到橡胶块4上时，通过连杆2带动吸能装置的铝块5，在铝块5上嵌有两个密封圈6来保证吸能装置的气密性要求，通过金属底座上的阀门4控制出气孔的气流量从而控制该阻尼器的能力释放率，从而达到吸收透射杆能量的目的。When the transmission rod of the Hopkinson pressure rod dynamic test system hits the rubber block 4, the aluminum block 5 of the energy-absorbing device is driven by the connecting rod 2, and two sealing rings 6 are embedded on the aluminum block 5 to ensure that the energy-absorbing device According to the airtightness requirements of the damper, the air flow of the air outlet is controlled by the valve 4 on the metal base to control the capacity release rate of the damper, so as to achieve the purpose of absorbing the energy of the transmission rod.
通过芯体上的金属弹簧11反弹芯体使其复位，为下一次测试做好准备。The metal spring 11 on the core rebounds the core to make it reset, ready for the next test.
