模态测试需要

zhouchao

现在我们需要对一个几吨重的东西做模态测试实验，得出相关参数。需要一套模态测试设备。大家给点意见，包括数据采集，加速度传感器，模态测试软件等选着哪个公司的什么类型的比较好。给出相关设备的参数和报价。最好能给出一个大体上的项目建议书报价等 谢谢了

B&K的，LMS的都可以，看你用多少通道了，通道越多价格越贵。

m+p Coda Utilized to Save Lives

m+p international’s partner All Temp Engineering recently fabricated and installed three coolers and three freezers at BloodSource, a not for profit company located in Northern California. BloodSource collects blood from volunteer blood donors, tests, processes and delivers blood to patients around the world at a moment’s notice. Regulated by both the FDA and International standards, BloodSource required both the coolers and freezers be accepted per their specifications and then certified before being put to use.


Coda utilized at BloodSource 

Utilizing m+p international’s Coda (Continuous Data Acquisition) system, air and product temperatures had to be monitored and recorded to document this critical environment. The coolers (can vary only +/- 1 degree Celsius throughout) and freezers (can vary only +/- 2 degrees Celsius throughout) range in size from 400 to 3200 cubic feet. The m+p Coda system was configured with the new VTI EX1032 LXIbus hardware to acquire temperatures at 12 points within each freezer/cooler. The user was able to accomplish multiple data acquisitions at the same time and did not have to wait to start the validation process on the next available cooler or freezer. This flexibility of acquisition cut the multiple 12 day testing time by 24 days. In turn the validations were finished a head of time. The EX1032 has 32 temperature channels and 10 voltage input channels for both local and remote data acquisition.

Since 1985 All Temp Engineering continues to maintain a successful engineering and service group, with high-level competencies in cascade refrigeration, liquid nitrogen based cooling and freezing systems, laboratory ovens, walk-in rooms, energy efficiency retrofits & system upgrades, control upgrades, thermal shock, altitude, HALT-HASS, humidity, vacuum and pressure systems, all aspects of designing and controlling environmental simulation and ultra-low/cryogenic cooling/freezing technology. 

Since 1948 BloodSource has been collecting blood donations and providing life-saving blood products to the people of Northern and Central California and beyond. BloodSource is committed to doing what’s right, a simple philosophy that has helped the organization grow from a single blood bank beneath a water tower in Sacramento to one of the premier blood centers in the world.
