摘要
针对传统测试缓冲材料振动传递率所用振动台价格昂贵、试验周期长的缺点,提出了利用冲击试验通过测量冲击激励和缓冲材料在给定静应力情况下的冲击响应来得到缓冲材料的瞬态振动传递率的方法。本文论述了这一方法的理论依据以及该试验方法的可行性。
Because of the fault that the cost of traditional vibration test-bed used to obtain the vibration transmissibility of cushioning materials is high, and the period of test is long, a method to obtain the vibration transmissibility of cushioning materials through measuring the impact power and the impact response under the static stress on the impact test-bed was put forward. The theoretical foundation and the feasibility of this testing method were discussed.
