Lecture Notes in Electrical Engineering: Necessity to Add Undergraduate Education of MEEM in China

The long-term development of medical equipment industry has to rely on the key technology of medical electrical fields. Due to the development level of China’s higher education is lower than foreign country in this field, the necessity analysis on establishing the Medical and Electrical Engineering Major is carried out in this paper, through analyzing national macroscopic policy and regional economic planning, based on provincial construction plan of Heilongjiang, in order to conform to the trend of the times and developing situation of the trade. Considering the overall above evaluation factor, the personnel training model is proposed finally with characteristic of the combination of medical, mechanical and electrical fields so as to improve employment rate and promote steady and rapid economic development and social harmony and stability.

Design and simulation analysis for maize stubble harvester

In order to reduce the towing resistance of the digging maize stubble device and ensure the indicators of reducing missing ratio and raising the harvest productivity when reaping maize, the new harvest technique was put forward, namely, stubble cutting shovel first stretch stubble ridge, and then maize rhizomes were collected by rhizome pick-up device and auxiliary pick-up device together. A pick-up tooth with U-structure and arc structure was designed. At first the motion coordination between rhizome pick-up device and assistant pick-up device and the motion interference among other parts of maize harvest machine were analyzed and checked by the help of motion simulation mould of Pro/ENGINEER software, and then the whole placement of all parts and their designs were improved, at last the maize harvest machine possessing compact structure and high efficiency was designed. The field experiments prove that the designed maize harvest machine can meet the design performance index and possesses the good work dependability, which is of great significance for subsequent research.
