锥坡是桥梁的关键部位,其形式直接影响到桥梁及桥头路基的安全,正交桥梁锥坡设计在相关手册中均有阐述,但斜交桥梁锥坡设计却很少有资料可循,导致设计、施工较为混乱。文章通过解析法推导了桥梁锥坡设计基本要素公式,供设计、施工人员参考。 相似文献

The effectiveness of ABS for the motorcycle has been evaluated by comparison with deal braking. However, it is almost impossible for the typical rider to perform ideal braking in an emergency. We conducted braking in a turn test by skilled and less-skilled riders, for the purpose of evaluating the effectiveness of ABS for the typical rider and obtaining data for a method of evaluating motorcycle ABS performance. It was shown that ABS for the motorcycle is effective for both skilled and less-skilled riders in terms of braking distance and vehicle stability. 相似文献

This paper is a continuation of a previous paper titled ??Modeling and Model Predictive Control for Hybrid Vehicle?? published on IJAT/2011 describing a mathematical model and design for a model predictive controller for tracking speeds and simulations. The present paper further describes a fuzzy logic controller for the smooth and quick engagement of an automatic clutch. The described controller uses both fuzzy logic and slip control algorithms to enable automatic clutch engagement. Clutch engagement and comprehensive simulations for the hybrid vehicle are conducted in MATLAB R2009s. The research described herein offers theoretical solutions for how to better control clutch slip and engagement within realistic parameters used for hybrid vehicles. Algorithms and operations of this fuzzy logic controller can be implemented in electronic control units for automatic clutch engagements and gear-shifting processes. 相似文献

Accurate and efficient contact models for wheel–rail interaction are essential for the study of the dynamic behaviour of a railway vehicle. Assessment of the contact forces and moments, as well as contact geometry provide a fundamental foundation for such tasks as design of braking and traction control systems, prediction of wheel and rail wear, and evaluation of ride safety and comfort. This paper discusses the evolution and the current state of the theories for solving the wheel–rail contact problem for rolling stock. The well-known theories for modelling both normal contact (Hertzian and non-Hertzian) and tangential contact (Kalker's linear theory, FASTSIM, CONTACT, Polach's theory, etc.) are reviewed. The paper discusses the simplifying assumptions for developing these models and compares their functionality. The experimental studies for evaluation of contact models are also reviewed. This paper concludes with discussing open areas in contact mechanics that require further research for developing better models to represent the wheel–rail interaction. 相似文献
