多轴振动试验台
航空航天:长条状或横梁类的试件,例如导弹,当单台试验达到设定的较大试验量级时,试件局部和夹具接触面应力过大从而导致局部失效损坏。 土木及结构抗震:土木领域的抗震模拟试验,其振动不能通过轴向分解,必须同时进行两点或多点的激振。 汽车及道路谱模拟:汽车领域的系统级试验,例如道路谱模拟,多次单方向模拟的试验方法与实际多维振动环境差异越来越大,影响受试产品可靠性的定量评定。 机械装备:机械装备的大型试件,单点激励无法保证振动激励的均匀性,试件上不同位置响应有较大差异,应力和位移分布不合理。

产品用途:
研发了多款多轴向多自由度试验系统,如双轴振动试验系统、三轴振动试验系统、三轴振动教学模拟试验系统等,相比较传统的单轴振动试验系统更加真实复现振动条件。在复杂的过程中,可以大大降低试验过度或试验不足的几率。
此外,与传统的单轴振动试验系统相比,多轴振动试验结果更加可靠,试验时间大大缩短。
