In order to realize high efficiency and flexible manufacturing for rotary surfaces
equivalent stress in sheet metal's center region and bendable rollers active region exceeds yield stress
efficient spinning technology (EST) is researched. It is the combination of multi-point forming and traditional spinning. Principle of EST is described
and plastic deformation is generated
traditional spinning method is compared with it
experimental result accords with simulation result. Feasibility of EST is validated by simulation and experimental results. (2011) Trans Tech Publications.
and characteristics of it are analyzed. Finite element analysis (FEA) model of disc-shape part is established
EST process is analyzed
equivalent stress and plastic strain distributions are analyzed. EST equipment is developed
and the experiments are made. Results indicate: EST process consists of four stages

Laser pulse code is an anti-jamming measures used in semi-active laser guided weapons. On account of the laser-guided signals adopting pulse coding mode and the weak signal processing
it need complex calculations in the frequency measurement process according to the laser pulse code signal time correlation to meet the request in optoelectronic countermeasures in semi-active laser guided weapons. To ensure accurately completing frequency measurement in a short time
it needed to carry out self-related process with the pulse arrival time series composed of pulse arrival time
calculate the signal repetition period
and then identify the letter type to achieve signal decoding from determining the time value
number and rank number in a signal cycle by Using CPLD and DSP for signal processing chip
designing a laser-guided signal frequency measurement in the pulse frequency measurement device
improving the signal processing capability through the appropriate software algorithms. In this article
we introduced the principle of frequency measurement of the device
described the hardware components of the device
the system works and software
analyzed the impact of some system factors on the accuracy of the measurement. The experimental results indicated that this system improve the accuracy of the measurement under the premise of volume
real-time
anti-interference
low power of the laser pulse frequency measuring device. The practicality of the design
reliability has been demonstrated from the experimental point of view.

Based on the principle of gyroscope and the structure of gyro stabilized platform
this paper gives the analysis and comparison of control strategies for stable platform included classical PID control
and three kinds of advanced strategies: Fuzzy Control
Sliding Mode Variable Structure Control and Active Disturbance Rejection Control. The compensation methods for stable platform's error are also discussed and evaluated based on the sources of error
especially for the non-linear friction and gyro drift. The paper provides the reliable methods for recognizing and improving the accuracy of gyro stabilized platform from the control strategies and error compensations. 2011 Chinese Assoc of Automation.
