Real-time simulation models based on multibody system dynamics can replicate reality with high accuracy. As real-time models typically describe machines that interact with a complicated environment, it is important to have an accurate environment model in which the simulation model operates. Photogrammetry provides a set of tools that can be used to create a three-dimensional environment from planar images. A created environment and a multibody-based simulation model can be combined in a Unity environment. This paper introduces a procedure to generate an accurate spatial working environment based on an existing real environment. As a numerical example, a detailed environment model is created from a University campus area.

The paper introduced a real time simulation model of 450 t/h circulating fluidized bed boiler (CFBB) combustion system and its development method in detail. It is an important part model of operator training purpose simulator, which is for Baoding Thermal Power Plant, Hebei, China. The simulation model is created with the support of STAR-90™ Simulation software, and developed by way of engineering modular modeling (EMM) method. It is mainly composed by 4 model blocks, i.e. PRECMBST, FBC2, CYCLONE and JVLV, which stand for gas duct combustor under the bed, furnace combustor, cyclone gas separator, and loop seal valve in the CFBB respectively. The simulation results indicated that the model could properly reflect the dynamic and static characteristics of the combustion system of the CFBB. It not only can be used for training simulators, but also for system optimum design and control system analysis.

The surgical skills required to successfully maintain hemostasis, the control of operative blood, requires considerable deliberate practice. Hemostasis requires the deft orchestration of bi-dexterous tool manipulation. We present our approach to computationally emulate both irrigation and bleeding associated with neurotologic surgical technique. The overall objective is to provide a visually plausible, three dimensional, real-time simulation of bleeding and irrigation in a virtual otologic simulator system. The results present a unique simulation environment for deliberate study and practice.

<span lang="EN-US">This paper presents the modeling and real-time simulation of an induction motor. The RT- LAB simulation software enables the parallel simulation of power drives and electric circuits on clusters of a PC running QNX or RT- Linux operating systems at sample time below 10 µs. Using standard Simulink models including SimPowerSystems models, RT-LAB build computation and communication tasks are necessary to make parallel simulation of electrical systems. The code generated by the Real-Time Workshop of RT- LAB is linked to the OP5600 digital real-time simulator. A case study example of real-time simulation of an induction motor system is presented.This paper discusses methods to overcome the challenges of real-time simulation of an induction motor system synchronizing with a real-time clock.</span>

Yield Monitoring

To solve the problem that yield monitoring cannot be done in real time during tomato harvesting in existing technology, a real-time yield monitor device on tomato harvester is designed by an three-dimensional software which is named Solidworks. This article describes the all structural characteristics and working principle of the device. Weighing belt, rollers and three kinds of sensors of the device are mainly designed and selected based on the working environment and technical requirements. The design of yield monitor device promotes popularization of the technology of tomato harvesting yield monitor on tomato harvesting machinery, makes the process of yield monitor in real time during tomato harvest realize automated, intelligently and informationized and provides a theoretical basis for the further study of tomato harvester monitoring technology.
