bekker meaning in English
贝克尔
Examples
- Based on the theory of bekker , this paper also analyzes the process of steering on flat ground and on a slope . this paper also considers the centrifugal force and the air resistance when tank is driving at middle or high speed
在分析坦克所受外力作用时，考虑了履带的滑动和横摆角，并且根据bekker的理论，分别讨论了坦克在水平面和斜坡上的转向过程，在分析过程中，充分考虑了坦克高速转向时的离心力的影响。 - Now some universities and institutes of china have made some samples of the lunar rovers and theirs wheels , but until now the wheel ’ s mechanical performance is seldom researched and tested . this paper will analyze the mechanical performance of the wheel and design a test - bed to test the performance of the lunar rover ’ s wheel . firstly , the mechanical characters of the soil are separated to press - sinkage character and shear character based on bekker ’ s theory , and common press - sinkage and shear models are introduced and the theory of lankine passive earth pressure is also introduced
根据bekker半经验法的基本思想,将土壤的力学特性分解为水平方向的剪切特性和竖直方向的承压特性,阐述了地面力学中常见的土壤的承压、剪切等力学模型,并引入了朗肯被动土压力理论,为建立车轮在松软土壤中前进和转向的力学模型奠定了基础,同时进行了实验土壤的剪切实验,测量了土壤的内聚力和内摩擦角等参数。 - These basic theories are helpful to construct model . some parameters of soil used for experiments are measured by shear experiments . secondly , mechanical models of the wheel - soil interaction when rolling and steering are constructed respectively based on the theory of terrain - vehicle and passive earth pressure
基于地面力学中的bekker承压模型和janosi剪切模型,建立了一种月球车车轮在松软地面上前进时的力学模型,根据被动土压力理论,建立了该车轮在转向时的力学模型,给出了所建方程及模型的数值解法。
