The different-speed mixer is used in the rubber industry widely. The dynamic response of different-speed mixer shaft is very key. Some displacement and dynamic stress response values of different-speed mixer shaft frequency are obtained by using the finite element method, which gives the basic theory for further systematic dynamic analysis and the structure design of different-speed mixer shaft.

Frame is an important truck part to connect and support engine, transmission, carriage and cab etc. It is important to analyze strength, stiffness and dynamic characteristics for frame design. This paper developed static analysis of a specific agricultural truck frame under two conditions of full load bending and reverse. The corresponding suggestions of structural modification were proposed. Then the dynamic response of truck frame caused by the external incentives was studied, namely harmonic response analysis and transient dynamic analysis. The paper not only analyzed whether the truck frame met the strength requirements, but also proposed the corresponding solutions for the possible cases of fatigue fracture and stress overloaded of the frame.

Abstract：The dynamic design method was used to analyze the vibrating screens, which can reveal the distribution of the dynamic stress in the main structure exactly and ensure safety and rationality of the structure design. The screens of the type 5XF150/180 grain screening machine were analyzed by the dynamic method. And modal analysis, harmonic response analysis and transient dynamic analysis were studied by ANSYS Workbench software. According to the calculated results ,dynamic property and kinetic parameters were determined. Then the key technology in the dynamic design was discussed, which provided a reference to the dynamic design of such large vibrating screens.

Aircraft Crashworthiness

AbstractTo improve the crashworthiness of civil aircraft, the design concept of energy absorption structure for civil aircraft is investigated. Two typical different design principles could be identified. The first category includes Helicopter and Light fixed-wing Aircraft (HLA), and Transport, Mid-size and Commuter type Aircraft (TMCA) are classified into the second group. Frame, strut and bottom structure are the three kinds of energy absorption structure for TMCA. The strut layout of conventional civil aircraft is studied and some energy absorption devices are adopted. High efficiency energy absorption structures such as the foam and sine-wave beam are employed as the bottom structure for both of HLA and LMCA. The finite element method is used to analyse and design energy absorption structure in aircraft crashworthiness problem. Results show that the crashworthiness of civil aircraft could be largely improved by using proper strut layout and excellent energy absorption device. The stiffness combination of frame and strut should be considered to get better global aircraft deformation. Supporting platform and failure model are the two core problems of bottom energy absorption structure design. Foam and sine-wave beam under the lifted frame could improve the crashworthiness of civil aircraft.
