落锤试验是模拟车辆之间的冲撞,用来研究缓冲器的性能和验收它的质量的一种方法,这也是目前世界各国普遍采用的方法。测量的主要性能指标是缓冲器的阻抗力、位移、容量等等。因落锤过程动能传递时间很短,缓冲器产生瞬态运动,阻抗力为瞬态量,同时数值很大,达几百吨力,准确测量它是 Drop hammer test is to simulate the collision between vehicles, used to study the buffer performance and acceptance of its quality as a method, which is currently widely used in countries around the world. The main performance indicators measured are the buffer resistance, displacement, capacity and so on. Due to the drop hammer process kinetic energy transfer time is very short, the buffer transient motion, the impedance is transient, while a large number, up to hundreds of tons of force, accurate measurement of it is
