Motor drive system is one of the core components of electric vehicles. To meet the electric vehicles performance requirements: starting, accelerating, climbing and other driving conditions demand, motor drive system requires high torque at low speed, high power at high speed, wide speed control range, etc. This paper takes a motor-driven electric vehicle system design as an example, from the control...
This paper studies a practical example of product data management (PDM) in a medium-sized manufacturing company in China. In PDM practices, some issues are common in all company because they are independent of the problems to be solved. However in PDM practices there are some issues relying on the specific operations, products and organizational state in different company. In this PDM practices, the...
This paper presents a fuzzy modeling with immune algorithm to search for the optimal solution in conceptual design of mechanisms. First, a new problem formulation model that involves fuzzy logic to reflect the imprecise nature of objectives is presented. Then, an immune optimization algorithm (IOA) is used as a key technology to find the optimal solution in many combinatorial solutions, which can...
Computer aided instruction (CAI) technology has been proved that it can strongly support teaching in improving class quality, students' studying efficiency and effectiveness. In terms of the requirement of general vehicle design course, this paper proposes a way to this kinds of course teaching by offering a practical teaching tool, which is based on supporting multi-engineering modeling and simulation...
