Abstract: According to this analysis, we designed a scenario on lower extremity rehabilitation robot communication system based on CAN bus and efficiently solved the problems of low signal processing, computing power and data transfer rate ability for the traditional means of communication of RS232 and RS485.The research deals with the characteristics of communication systems and topological structure, and specifically, with CAN bus protocol design and hardware and software implementation aspects of Communication System designing for some robot sensor.

Abstract: The combination of composite rotor and mounting shaft is mainly realized by press fit. In the paper, the initial stress distribution of interference fit between composite rotor and mounting shaft, the centrifugal stress due to high speed rotation are studied systematically. Based on the principles of material failure and detachment constraint at high speed rotation, a calculation method for the appropriate interference is proposed. Finally, specific example is analyzed to verify the feasibility of this method.

Abstract: The design for multi-function self defense device can strengthen the protection for females, also provide automatic alarm and trace the location of the device (user).Traditional defense devices can not combine defense function with automatic alarm at the same time. GPS system, infrared communication and single chip microcomputer were used .The device can be used when people go out alone. It can spray pungent water, emit strong light, call the user’s relatives as well as send out current location massage in a secret way. The implement of the device demonstrate that the device could be employed satisfactorily when the users need effective help in emergency.

Abstract: Collaborative simulation on characteristic parameters of the cylinder mechanism was realized by Pro/E and AWE software. Optimum allocation about the structure parameters like wall thickness, width, diameter and speed was completed based on comprehensive consideration of static strength and stiffness and dynamic characteristics of modal. The simulation result shows that the optimization scheme was beneficial to the yield and quality of cardings which lays the foundation for further development of the cylinder mechanism.

Abstract: In the paper, the kinetics of the mine car when it sports on the slope are analysized and calculated, characteristics of the rope brake energy absorption are designed and studied.

Abstract: In this paper, a new viscoelastic damper design for heavy trucks is presented and a calculation formula of viscous damping force considering the effect of Viscoelastic Fluids (VF) flow rate is carried out. By numerically simulating this equation, curves of the viscoelastic damper performance curve is obtained, and the results show that theoretical calculation result and the test results are well consistent, with the exception at the start point. Theoretical curves are more plumpness in compared with test curves.

Abstract: In this paper, the gear-position decision method based on 3-parameter the optimal economical shift schedule for Automatic Manual Transmission (AMT) of Parallel Hybrid Electric Bus (PHEB) is proposed. Vehicle simulation model was built by using ADVISOR simulation software. The simulation results show that 3-parameter shift schedule has improved in economical performance of PHEB compared with 2-parameter shift schedule.

Abstract: The simulation model was established by ADAMS/CAR to study the torsion-beam rear suspension’s kinematical performance. The changes of automobile handling stability characteristic parameters were analyzed in driving condition. The simulation results show that the suspension kinematic analysis data can be applied to the relevant design and development work to provide a basis for study of automobile handling stability and ride performance.

Abstract: The development status and research progress of inclined plate sedimentation equipment, as well as the research progress of how to prevent the blockage of sedimentation channel were discussed. The main disadvantages of traditional inclined plate thickener were analyzed. A kind of new type lamella thickener which could vibrate the inclined plate was introduced. The core technologies of the vibration lamella thickener are that the inclined plate sedimentation channels are integrated and modularized, the integral sloping plate group module are suspension supported by using springs and each module mounted an independent mechanical vibration excite. By implementing an intermittent high frequency weak vibration to the sloping plate group module, the regular automatic cleaning of the surface of inclined plate was carried out, which could prevent the fine materials adhesive to the oblique plate and guarantee the settlement channel is not blocked, so as to achieve the purpose of long-term stable operation of the equipment. Vibration lamella thickener has been used in many concentrators successfully, including the classification of feed pulp, desliming and thicken of middle materials, dewatering and thickening of concentrate and tailing, and paste discharge of tailing thicken at al.. It is highly valued from clients by their good application in practical production.

Abstract: Solid-web double-beam component is widely used in the dipper handle of excavator, whose mechanical behaviour belongs to compression-bending member and mainly satisfies the strength requirement. In this paper, it starts from the design principles of steel structure and elastic theory, determines the dimension of the main cross-section and the reverse tube under guidance of optimization, and provides initial data for the detailed design. The method has common direct sense.
