| Abstract: | A certain pyrotechnic release device is mainly used to realize the connection and separation of large loads. To reduce the large release impact, theoretical researches are carried out and an improved design based on the cellular buffer principle is proposed. Through the verification test, the impact after the improvement is reduced from above 11 000g to below 1500g, showing that the impact reduction is remarkable. |
