This paper presented the necessary of the biomass briquette technologies in the north rural areas of China. The biomass briquette technology can be used as a pretreatment technology for the other high-efficient using straw technology, especially for the direct combustion technology. Biomass briquette has obvious advantages such as good combustion characteristics, convenience of storage and transportation...
This paper presented the research results on the feasibility of the engineering application of high-efficient using straw technologies in the north rural areas of China. The biochemical conversion, the thermo-chemical conversion and the straw briquette process are all high efficiently straw stem using technology. The long wintertime and the cold climate limit the effect of biochemical conversion....
This paper mainly discusses the fundamental problems on the system design of the Hardware-In-the-Loop (HIL) simulation. Through analyzing the simulated object system and the HIL simulation system for on-orbit docking dynamics, the design problem of HIL simulation system is defined as a rebuilding problem of the dynamic characteristics of the HIL simulation system. This idea provides the solution to...
In order to accurately and quantitatively evaluate the authenticity of the simulation results of the HIL (Hardware-In-the-Loop) simulation system for on-orbit docking, a validation model for the HIL simulation system for on-orbit docking dynamics was set forth. It is a no-damping vibro-impact model. Base on it, a validation mechanism and an experimental validation procedure were elaborated. The evaluation...
The research work in this paper is oriented to establish a real hardware-in-the-loop (HIL) simulation system to reappear the on-orbit docking process on the ground. The docking frequency is discussed based on the analyzing the characteristics of docking mechanism. The time delay and time lag problems in the HIL simulation for on-orbit docking are quantitatively discussed. Furthermore, the compensation...
This paper present a new method for the integration of the HIL simulation system for on-orbit docking. First, the problems, such as stability, in the integration of the HIL simulation system arc discussed. The HIL simulation tasks are discussed based on the analysis of the characteristics of the docking mechanism. A new idea and procedural to integrate the HIL simulation system is presented. The two-degree-of-freedom...
