Digital Twin Technology (DWT) is a new type of computer software and hardware used in measuring the position and orientation of rotating and non-rotating parts on an object. This system is similar to conventional rotational positioning systems,but is far more robust and reliable.
Digital twin (DWT) is basically the application of two separate techniques that have never before been thought compatible,namely two separate virtual measurement entities (analog components) and two separate virtual digital representation (digital components). The digital representation is then combined to provide a unique and exact result.
The analog components are normally known as velocity reference units or VREFs. These units allow precise measurement of velocity,acceleration,displacement and position. A DSTT system will provide an absolute value of velocity along with the corresponding acceleration and displacement data.
The digital representation is then combined with the virtual measurement components to give the final product. The result is then converted back into an absolute value. The relative values of the VREFs and digital representation are determined by DSTT software.
Because analog components are directly measured and converted to a digital value,DSTT has significantly less overhead than conventional systems. As the result,the system is extremely reliable,with low maintenance costs. Digital twin technology can be integrated into existing rotational measurement software such as Rotomatrix or RotorVista.
The advantage of digital representation is that it provides an accurate value in real time without the need for manual measurement. A DSTT system is also able to be automatically integrated with the other rotating parts of the system. This allows the entire system to provide precise information at once. It can even be integrated with an existing position measurement system for automatic measurement results.
DSTT systems have also shown a lot of promise as a tool for robotic manipulation,including autonomous robots,precision robotic tools and motion planning. The system is able to measure and analyze the positions and orientations of a wide range of moving objects.
Although digital twin technology is still in its early stages,the advantages of its use are well documented. With continued development and improvements,the systems may soon become a major component of many modern-day robotics systems.
Digital twin technology is used in several applications in the aerospace industry,as well as in various industrial applications. It is especially useful in the robotics field because of its high level of reliability and accuracy. Other applications include the military,aerospace,biomedical,automobile and marine applications.
The main disadvantage of digital twin technology is that it only works with one type of measurement. For example,velocity and displacement measurements cannot be accurately converted to an absolute value. Digital representation requires a different type of measuring device.
Other disadvantages of DSTT include the requirement for complex measuring equipment,expensive equipment and software. There is also the need to provide a large number of digital measurement points,and more space for storing measurement results.
However,DSTT products can also be used for analog products,such as velocity and displacement measurements. In the analog world,a single measurement can be converted into an exact value,depending on the method used.
Analog twin is capable of producing the same absolute value and result as velocity and displacement measurements using two different methods – the integral form of the method,or as a direct representation. In addition to this,DSTT can also generate multiple outputs,such as absolute value,relative value and speed range.
A digital representation has many advantages over analog twin. The main advantage is that digital representations can be used for a wide range of measurements with a single system and are less sensitive to errors.
Analog twin can only produce an absolute value and may produce multiple outputs if more than one method is used. Digital representation may also fail to generate the desired output,if more than one measurement is required.
Some drawbacks of digital representation also exist. One limitation of the DSTT method is that it cannot produce a velocity or displacement measurement at the same time,in the same area. This means that there may be two or more measurements to be taken,and they will not be converted correctly into an accurate value.
