Published: December 2014

The aim of this paper is to emphasise the importance of production levelling – Hejiunka - proper understanding. The Hejinuka principle is described in literature as a paradox: you use a fixed rigid schedule to increase efficiencies in order to become more flexible. It turns out to be the best way to get out of the vicious circle of fire-fighting, and overcome deficiencies in overall performance triggered by these continuous emergencies. The counterintuitiveness of this paradox makes it difficult to understand how the method works. The solution proposed by Toyota based on production levelling is also counterintuitive and hard to replicate. The actual status of production levelling implementation will be described on an example of an automotive producer – Central european OEM - CEO.

Published: December 2014

Dragonflies possess one of the most maneuverable flights among various insects. As the bionic Micro Air vehicles (MAVs) with the flight capabilities like dragonflies have been widely applied, detailed studies of dragonfly flight become critical and necessary for improvement and accomplishment of MAVs design. The phase relation between the forewings and hindwings is the most distinct feature of dragonfly flight and it plays an important role in the aerodynamic performance. In this paper, both tethered and quasi-free flapping flight of the dragonflyPantala flavescenswas filmed using a high-speed camera in indoor laboratory. Dragonflies tend to flap in-phase when an additional force is expected, while out-of-phase flapping is conducive to the stability and control of flight. In the takeoff maneuver, the large-and small-amplitude wingbeat alternated. Dragonflies obtain a high acceleration rapidly by the suddenly enlarged wingbeat amplitude which increases by 42%, and maintain the velocity and make ready for following acceleration by the small-amplitude but high-frequency wingbeat with amplitude decreases by 51% and frequency increases by 30% relatively.
New Guidance Law Design with Multiple Object Constraints for Guided Rocket-Propelled Missile
Authors: Duan Xiao Ju , Xue Xiao Zhong , Liu Peng Yun
Published: December 2014

A new approach is designed to the guidance of rocket-propelled missile with multiple object constraints. It allows the rocket-propelled missile to reach its target with a close to zero falling angle at a least time-of-flight (TOF). Instead of deriving the optimum guidance law by a series of linear quadratic optimization methods which results in guidance laws being complex, the new guidance law adopts a mixed framework composed of a modified PN guidance command and a TOF guidance command. The modified PN guidance is designed based on measured state information including missile position, flight-path angle and acceleration, which yields zero-miss-distance and zero-falling-angle. The TOF guidance command is determined in quadratic multinomial with respect to TOF error that is estimated with missile velocity reduction due to aerodynamic drag. Simulation results are presented to show that the proposed guidance law performs favorably in multiple object constraints.

Authors: He Cheng Kun , Zhang Jun Zhi , Wang Li Fang
Published: December 2014

Regenerative brakes offer the opportunity to improve a vehicle’s braking performance in emergency situation. This study investigates slip ratio emulation on a test bench to enable these issues to be studied in a lab. Compared with vehicle drive cycle emulation on a test bench, the slip ratio emulation on a test bench requires higher bandwidth because of the higher dynamic requirement of slip control than that of vehicle energy management. Toward this end, a feedforward compensation method that could also prevent the amplification of the noise from the sensor is designed for this based on a linearized wheel slip equation. The results of simulations and tests indicate that the proposed slip-ratio emulation method can emulate the dynamic variation of the slip rate effectively.

Preloaded piezo actuator was introduced to provide biomimetic vibration for needle during needle insertion into a pork liver, just as a fascicle insertion into the skin by a mosquito. The experimental results showed that the penetration force was reduced 26.7% compared with the force without biomimetic vibration.

A new gel type slow-release solid chlorine dioxide was prepared by mixing two gels together, which were Super Absorbent Polymer (SAP) absorbing sodium chlorite solution and solid acid solution, respectively. The optimal formula was determined by single factor experiment, and the effect of the temperature on chlorine dioxide release rate was investigated. Using tartaric acid as the solid acid, the release rate peak value of chlorine dioxide is 1.61 mg/h, and the release rate become slower of 1.09 mg/h at 72 h and 0.6 mg/h at 144 h, which shows a smooth and sustaining release process. When the volume of water is 25 mL, the optimal formula is SAP:3.5g, sodium chlorine:1.5g, anhydrous sodium sulfate:1.5g, tartaric acid:2g. The release process became more intense when the temperature became higher. The results indicated that this gel type slow-release solid chlorine dioxide should be suitable for eliminating formaldehyde and stink in the environment.

Reduction unit for high-speed train is an important component. However if faults of reduction unit occurred, the damages such as material and human damage have been caused. To prevent the damage, it is necessary to study reduction unit monitoring for high-speed train. We conducted spur gear specimen test which was crack, breakage and pitting tests and analyzed FFT, Sideband energy ratio (SER), RMS, crest factor, and kurtosis. There was not distinct difference between no-fault and pitting condition at RMS, crest factor and kurtosis. But SER increased depending on crack condition. In breakage test, all parameters had difference between no-fault and breakage condition.

Based on the first panel of some coal mine in the western loess tableland, this thesis has carried out three-dimensional exploration. The emphasis of experiment is shooting factor(well depth、dynamite), at the same time, the experiment of instrument factor and receiving factor has been carried out to choose the best shooting factor and receiving parameter. By proper layout observation system, elaborate static correction and comparison about various methods of static correction, this thesis has drawn the following conclusions: (1) From the experiment of well depth, interference wave is mainly composed of multiple refraction wave and surface wave, in general, the greater of the well depth, the smaller of the interference of refraction wave, and the interference of surface wave has dropped. Refraction wave energy is related to excitation horizons; (2)From receiving profile during the process of the experiment, the wave detector of dominant frequency being 25Hz has little difference with the wave detector of dominant frequency being 60Hz, so each has its advantages. The levels of reflection wave groups in coal seam of 60Hz profile are relatively abundant, and the continuity of the bottom reflection wave in coal seam of 60Hz profile is greater than 25Hz profile, and it is easier to trace, compare and explain. (3) From the process of the experiment, the complexity of surface conditions has little influence on data, on condition that being constructed strictly and completing static correction, it is absolutely possible to finish geological exploration.

Design Optimization to Reduce Variation in Manufacturing Process
Authors: Chen Hong
Published: December 2014

The variation on the product functional parameter has been shown to cause potential failures. These potential failures may not be caught in production line, but become the reason of customer complaints. To enable the development of robust method to detect variation, this work explores the possible sign from the data of sector reports and transforms the questioned data to the variation by Six Sigma Methodology. The key techniques of DMAIC, MVA, SPC and RSMDOE are utilized. The method is designed with three phases: firstly it is to analyze the data from the sector report to detect the peculiar value. Then the performance is evaluated to identify the variation. In the last step the issue related to the variation is solved by design optimization. The method is evaluated in the manufacturing site with the material consumption data, and the excessive 20% consumption caused by the variation is saved, which demonstrates this variation detection method is in feasible and efficient manner for quality management.
