237.基于ANSYS的汽车后视镜振动模态分析和结构优化设计
[汽车制造业] [2014-03-21]
In this paper,we use the finite element software ANSYS to simulate the vibration frequency and vibration modals of the car rear-view mirror under the condition of excitation sources.Based on this and the strength analysis results of the rear-view mirror,we make a optimal design of the rear-view mirror structure.We get five-order vibration modals in working condition and analysis the size of displacement and deformation,and dynamic characteristics.The results show that because of the low modal frequency,the car rear-view mirror is easily inspired by the engine,powertrain system and road to vibrate.

238.项目总结报告：汽车废热回收热电技术的发展（2005.5.23——2011.10.31）
[汽车制造业] [2014-03-21]
We conducted a vehicle analysis to assess the feasibility of thermoelectric technology for waste heat recovery and conversion to useful electrical power and found that eliminating the 500 W of electrical power generated by the alternator corresponded to about a 7increase in fuel economy (FE) for a small car and about 6for a full size truck.We obtained critical vehicle level information for these driving cycles that enabled a highlevel design and performance analysis of radiator and exhaust gas thermoelectric subsystems for several potential vehicle platforms, and we identified the location and geometric envelopes of the radiator and exhaust gas thermoelectric subsystems.
