求电动式激振器,要求30kHz
求电动式激振器,要求30kHz 国内哪家有? 看他们的网页,国内的厂商好像都没有。东菱好像也只到10k,进口的可能高一点要到25k,具体你得问厂商了。 进口的有哪些厂商啊! 推力要求多大!这种要求应该东西比较小吧!{:{13}:} 频率这么高的振动台推力肯定很小,最多也就几公斤吧 看你的推力和最大负载。 国内产品压电式的可以做到5万赫兹,2000g,但是只能做加速度计较准这样的小负载。国外的高频电动台也是做小负载的。
压电式的不想要,我想问下电动式的能到多少! 推力很小,几牛就好! 最高也就十几K,高不了。 本帖最后由 fridayxi 于 2010-10-9 20:56 编辑
德国TIRA有一种台子可以做到25k,不过实际上这么高的频率下,各种指标已经失真了。如果需要我把资料发给你。 LW126HF.138-13
The LW126HF.138-13 is a high performance system which incorporates the compact ET-126HF high frequency shaker. This system offers the maximum performance from the ET-126HF shaker without a cooling blower. Full system ratings are available up to 14,000 Hz with reduced operation up to 20,000 Hz. This system is used for both general purpose high frequency testing and transducer calibration requirements. A voltage-proportional-to-output-current output signal is provided for modal test and other applications requiring force monitoring. The larger mounting surface of the ET-126HF easily supports the calibration of most vibration transducers and smaller high frequency assemblies and components for general purpose testing not requiring high acceleration testing. The shaker can support relatively heavy loads and is perfectly matched to the amplifier, which makes this the most versatile system of its size.

能发份资料给我么,我的邮箱suwei8888@126.com 今天在网上查资料,看到有 LABWORKS公司的振动台,其实是激振器,工作频率到14K,

貌似Labworks可以做到20kHz
