查询词典 front-wheel drive

The obstacle (the altitude of 900 mm) process for both sides of a planetary gear train was analyzed in ADAMAS. It is proved that the physical dimension of the planetary gear train, bodywork center position and attachment coefficient are the key effect factors. The driven moment, velocity and normal pressure sharply increased as each wheel surmounting obstacles, but they were moderate after the front wheel came over the obstacles. Another weaker pulse occurred when the rear wheel began climbing, and then the parameters reached a plateau.

行星轮系的结构尺寸、车体质心位置及附着系数对越障高度影响较大；各轮系越障时出现驱动力矩、速度和正压力急增的现象，前轮系的前轮越上障碍后，各参数值趋于平稳，后轮越障时又出现瞬时脉动，但脉动较小，后轮系也有相同的变化趋势，各轮的阻力矩和输出功率与正压力变化趋势相同。

The relationship of front and weather: They had the right conception of "front" and "air mass" as scientists, but some students were easily mixing the concept of cold front , warm front and stationary front.

锋面与天气的关系：对於锋面与气团的概念具有符合科学家的概念。但是对於冷锋、暖锋及滞留锋的天气状况，部分学童仍有混淆的情形。

In this study, we select 4 factors: depth ahead water-front, stability of water-front, extensity rear water-front on land, water-front's traffic settings and cities supporting, upon which the indices system for evaluating the exploration conditions of water-front resources is built. And then, in term of this system and by employing GIS and mathematic methods, the waterfront from Jiujiang to Xinji Towhead section along the Yangtze River is evaluated.

选择九江－新济洲段长江干流为研究区域，该文在进一步扩展长江岸线资源研究的区域范围的同时，通过建立包括岸前水深、岸线稳定性、岸线陆域宽度、岸线集疏运条件和岸线城市依托条件为主要评价因子的指标体系，运用GIS手段和定量方法，探索了长江岸线资源的开发条件评价。

To eliminate abnormity wear of tires in double-front-axle system of heavy truck, the kinematics and dynamics analysis method is set forth. On the base of the results for heavy double-front-axle truck load distributing and manipulate stability, tire uniformity load condition and deficiency steering characteristic condition of heavy double-front-axle truck are put forward. Steering trapezia space movement formula, double-swing-arm space movement formula and double-swing-arm movement formula in actual status of heavy double-front-axle truck are fetched. Optimization models of steering trapezia and double-swing-arm are founded and optimization arithmetics of transmission system in double-front-axle steering are compiled.

本文以消除重型汽车双前桥转向系统轮胎异常磨损等为目的，阐述了双前桥转向系统的运动学、动力学分析方法；在分析了双前桥重型汽车载荷分布和操纵稳定性的基础上，提出了双前桥重型汽车轮胎均载应该满足的条件、双前桥重型汽车具备不足转向特性应该满足的条件；推导了双前桥转向梯形空间运动关系式、双摇臂机构空间运动关系式和双前桥汽车实际工况下的运动关系式，建立了转向梯形和双摇臂机构优化设计模型，编制了双前桥转向传动系统优化算法。
