摘要:: 为实现高速运动设备在阻尼器作用下以低阻抗力、短距快速制动缓冲的目的，降低高速冲击对设备的损伤，该文设计了一种耐高速冲击阻尼器，通过对阻尼器内部结构进行优化设计，并采用缓冲垫加气液阻尼器的多级缓冲方式消除高速冲击瞬间产生的高峰值力，从而降低对运动装置的瞬时冲击值。首先基于气液阻尼器设计了耐高速冲击阻尼器的基本结构，然后通过对阻尼器进行静态压缩试验和超高速冲击试验，测得了冲击过程中阻尼力和缓冲位移，并根据试验结果对阻尼器设计参数进行修正，优化了内部结构，最后在使用现场进行了实际测试，获得测试结果并进行分析。结果表明，该耐高速冲击阻尼器可满足重量为30 kg高速运动装置以30 m/s速度短距快速制动缓冲、且最大阻尼力值不超过40 kN要求。

Abstract:: In order to achieve the purpose of low-impedance force and short-distance rapid braking buffering of high-speed motion equipment under the action of the damper, and to reduce the damage to the equipment caused by high-speed shock. In this paper, a high-speed shock-resistant damper is designed. By optimizing the design of the internal structure of the damper, and adopting the multi-stage buffering method of cushion pad and gas-liquid damper, the high peak force generated at the moment of high-speed shock is eliminated, thereby reducing the instantaneous shock on the moving device. Firstly, the basic structure of the high-speed shock-resistant damper was designed based on the gas-liquid damper. Then, the static compression test and the ultra-high-speed shock test were performed on the damper to measure the damping force and buffer displacement during the shock. The design parameters were revised, and the internal structure was optimized. Finally, the actual test was carried out on site, and the test results were obtained and analyzed. The results show that the high-speed shock-resistant damper can meet the requirement of a high-speed motion device with a weight of 30 kg and a rapid braking buffer at a speed of 30 m/s for a short distance, and the maximum damping force value does not exceed 40 kN.
