This release brings new features in the Acquisition for generating a Once Per Rev signal from the probe signals with both hardware and software solutions. We still recommend a physical OPR but these new features provide options where either fitting an OPR is not possible or the existing one has failed. We also have the ability to generate an OPR after the test from the recorded probe data. There is a YouTube video covering this functionality so please check it out. If you have an update subscription then download the software here.
We have added the ability to calculate the best axial position for the probes into the Editor. If you have a design sublicense for probe placement then this is included for free. The file format for the mode shape data is published in the Editor manual and a demo file is available in the downloads section. There is a YouTube video covering this new functionality so please check it out.
Bug fixes and enhancements.
YouTube Channel Update
We have also released some tutorial videos onto our YouTube Channel. Due to the current situation we will not be travelling for training sessions so the aim is to cover the basic operation of the software, pointing out features and functionality that even existing users may have missed. Feel free to head over and take a look.
Update – The demo files used in the videos are available from the downloads section.
The Injector mode of MultiTool allows the user to adjust one or more blades in a dataset, either real or simulated. This can be done either by injecting a permanent DC shift to the blades position, injecting an impact condition or propagating a crack that moves the DC position of the blade with speed.
The user is also able to write their own crack growth algorithm as part of a Plug-In architecture. Please see the manual for more information.
EMTD held its second BTT technology conference In Lingang China in July 2017, it was attended by many people from both Academia and Industry between Monday 24th July – Wednesday 26th July. The event began with a Keynote speech from Prof A.J. Wang of SJTU talking about the problems of reviewing vibration analysis data and the huge potential and opportunities for BTT methods. A number of future research topics were discussed along with new and novel applications.
The days also included small group tutorials where a wide variety of topics including EHM, probe technology and cost of ownership were discussed.
Feel free to contact us to find out more information or the date and content of our next training courses.
At the School of Mechanical Engineering, Shanghai Jiao Tong University, Chengwei Fan is providing technical assistance for EMTD BTT systems. He is currently researching new analysis methods which we hope to incorporate in future systems.
EMTD are pleased to announce a partnership arrangement with TALENT based in Shanghai, China. TALENT will provide all of the installation, operation and training services for the EMTD suite of Blade Tip Timing technology in China.
We are also continuing our work with Shanghai Jiao Tong University to develop the use of BTT for a number of aerospace applications including Cross Wind testing and core compressor testing at the new Turbine test facility in Linggang.
EMTD made a number of presentations covering BTT technology awareness , in depth analysis techniques and the potential use of BTT in component certification testing to the Civil Aviation Administration of China (CAAC).
We hope to return to Shanghai in the near future to continue building internal measurement capability for Chinese companies.
EMTD attended the EVI-GTI meeting in Berlin at the end of September. Here we gave an update on the problems of developing Blade Health Monitoring (BHM) for aerospace applications. We are seeing great interest for this form of technology especially from the power generation industry.
EMTD launched a call for partners for a proposal under the Horizon 2020 programme and we now have had sufficient interest to begin the process of submission. We have tied up with a major power generation business in Europe in creating the proposal.
Our links with University of Manchester PhD programme is beginning to show signs of progress and we are now participating in a second round of measurement research. Further afield we are forging links in South Africa for the future development of the Blade Tip Timing technology.
One of our strengths is in providing a measurement consultancy service to help companies new to the advances in measurement choose the correct technology for the task and to manage their expectations. Unlike many turn-key suppliers EMTD intend to equip end users with the knowledge to apply and develop instrumentation with their own resource if required.
We have now begun shipping our networked BTT data acquisition system and MultiTool software to selected customers. Our next training course will take place in Shanghai week commencing 26th November 2016
