目前 ,我国的减振器试验台多数采用单动式结构 ,虽然可同时对 4支减振器做疲劳试验 ,但是如果有 1支减振器在试验过程中出现损坏 ,将影响试验台的正常试验 ,并且试验周期长、耗时、耗电 ,以减振器试验 50万次计 ,约需 1 3小时。由于双动台与单动台结构形式不同 ,当 4支减振器中 At present, most of the shock absorber test rigs in China use a single-acting structure. Although fatigue tests can be performed on four shock absorbers at the same time, if one shock absorber is damaged during the test, it will affect the normal test bed Test, and the test cycle length, time-consuming, power consumption, shock absorber test 500,000 counts, about 13 hours. Due to the double-action platform and single-action platform structure in different forms, when the four shock absorbers
