The virtual prototyping model of Crank and Link Mechanism of Engine was constructed on ADAMS software by three dimensional model which produced on three dimensional modeling software; Through theoretical analysis of inertial force and moment of Crank and Link Mechanism, dynamical simulation was carried on in ADAMS software, and then the position of mass point of Crank and Link Mechanism of Engine...
Take support structure as the object, studied the multi-objective optimization of optimization layout of structural materials and maximize natural frequency under multiple load cases. Based on the SIMP (solid isotropic material with penalization) method, compromise programming method was adopted to define objectives of multi-objective topology optimization. With the supporting structure for the study,...
Statistical analysis of massive data is becoming indispensable to science, commerce, and society today. Such analysis requires efficient, flexible storage support and special optimization techniques. In this demo, we present RIOT (R with I/O Transparency), a system that extends R, a popular computing environment for statistical data analysis. RIOT makes R programs I/O-efficient in a way transparent...
Based on the previous researches and according to the milling characteristics of ball-end milling cutter, the cutting force model is established. Using empirical formula, the feed rate of NC codes of machining free-form surface is optimized under constraint of nearly constant cutting force, and so as to decrease the fluctuation of cutting force. Thus, the machining quality and efficiency of part are...
Shift schedules both for optimal dynamic performance and fuel economy are proposed in this paper for vehicles equipped with dual clutch transmissions. A range simulation model for DCT vehicles has been established to evaluate the effects on dynamic performance and fuel economy. A fuzzy logic controller for engine throttle and a PID controller for brake force are used for vehicle operation. The simulation...
An automotive active suspension system composes of a mechanical structure and a feedback controller. Conventionally, these two elements are designed sequentially, with the controller design subsequent to that of the mechanical structure design. The traditional design method cannot obtain the global optimum performances for the system. This paper presents an approach to integrate structural and control...
An ultra-precision vibration isolation platform composes of a mechanical structure and a feedback controller. Conventionally, these two elements are designed sequentially, with the controller design subsequent to that of the mechanical structure design. The traditional design method cannot obtain the global optimum performances for the system. This paper presents an approach to integrate structural...
