	Structural design of primary mirror subassembly for space telescope (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Mechatronics and Applied Mechanics, ICMAM 2012, December 8, 2012 - December 9, 2012, Taiwan 作者: Xu H. 收藏 \| 浏览/下载：63/0 \| 提交时间：2013/03/25 In order to design a large aperture primary mirror with the diameter of 1150 mm the parameters impacting on gravity deformation of the mirror were analyzed and discussed in detail including material selection diameter-thickness ratio the number of the support points location selection and lightweight structure etc. A novel space mirror structure system was put forward and its back was opened and supported by six points on back. The dynamic and static and thermal characteristics were analyzed based on the finite element method. Analysis results showed the surface figure accuracy reached to RMS 14.5nm under the action of gravity load along the optical axis direction and the first-order natural frequency was 214Hz which met to the designed indexes requirements.

	Lightweight design and analysis of support structure of certain UAV engine (EI CONFERENCE) 会议论文 OAI收割 2012 International Conference on Electrical Insulating Materials and Electrical Engineering, EIMEE 2012, May 25, 2012 - May 27, 2012, Shenyang, Liaoning, China Xing X.; Liu B.; Han X.; Jia H. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 Support structure of UAV (Unmanned Aerial Vehicle) engine is the important support for UAV engine playing a support role and bearing extremely complex load so its lightweight strength and dynamic characteristics have a great influence on high performance of UAV. This paper focuses on UAV having the requirement of high performance and stability to the support structure of engine and uses the software of MSC.Patran and MSC.Nastran and topology optimization criterion to lightweight design and analysis the support structure of UAV engine under the premise condition of existing constraints. Then the static strength and modal are analyzed for the result of lightweight design and the strength of the model and dynamic characteristics are verified.

	The lightweight design of the inner framework of the opto-electronic stabilization platform based on finite element analysis (EI CONFERENCE) 会议论文 OAI收割 2011 IEEE 18th International Conference on Industrial Engineering and Engineering Management, IE and EM 2011, September 3, 2011 - September 5, 2011, Changchun, China Zou Q.; Ma H.-L.; Hu Y.; Ding J.-W. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 The airborne opto-electronic stabilization platform should have the characteristics of high requirements for stability tracking accuracy and lightweight. In order to verify the rationality of the main load-bearing structure the inner-gimbal finite element analysis was performed. Because of the poor working conditions of the airborne opto-electronic stabilization platform and the wide range of working temperature variation -45 C 60 C according to the actual working environment air-resistance and temperature were added to the loads of the inner-gimbal in analysis. What's more based on the analysis results lightweight design was performed to the initial model and 64.37% of mass was decreased. The remarkable effect was obtained. This research is going to be instructive to design and production of the airborne opto-electronic stabilization platform in the future. 2011 IEEE.
	Design and analysis of power system of micro-electromechanical actuator (EI CONFERENCE) 会议论文 OAI收割 2010 2nd International Conference on Industrial Mechatronics and Automation, ICIMA 2010, May 30, 2010 - May 31, 2010, Wuhan, China 作者: Zhang J.; Zhang J.; Zhang J. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 In order to apply the electromechanical actuator to tactical mini-missiles maximum rotational speed of output shafts is greater than 250/s. Test results basically correspond to the requirement of technical indexes. It is proved that this analysis and design method is congruent with the design of micro-electromechanical actuators this paper researches on the key technology such as load-bearing ability the system bandwidth can reach 25.3Hz on the condition of no load and 23.4Hz on the condition of load thus the method is feasible. 2010 IEEE. rapidity and miniaturization of the micro-electromechanical actuator power system based on the ball screw. First according to specific technical indexes the power electromechanical time constant and the size of the motors are screened originally through theoretical analysis. Finally based on the characteristics of ball screw transmission load locus of the micro-electromechanical actuator dynamic system is theoretically analyzed and the optimum speed ratio is determined through parameter optimization. The results of the double closed loop controlled test on the principle prototype show: the system can operate normally with 2.5N.m hinge moment
	The research of control strategy on AOD furnace tilting system (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Logistics Systems and Intelligent Management, ICLSIM 2010, January 9, 2010 - January 10, 2010, Harbin, China Ma H. T.; You W.; Chen T. 收藏 \| 浏览/下载：17/0 \| 提交时间：2013/03/25 In view of the low speed the heavy load reversing the frequently brake the intense impact characteristics of AOD furnace tilting system The double closed-loop with feedforward is used. Position regulator and speed regulator use PID algorithm.And the speed loop is designed based on vector control. This control system was simulated by MATLAB Simulink software. The simulation result showed: Adjustment time is 8s the position steady-state error is 0 so it has achieved the demanded target of 0.12 radian static error fully. 2010 IEEE.
