【摘要】 根据油液的不可压缩性,可用以相位角为自变量的三角级数来表达路面不平度引起液压悬架多轴车辆车架的垂向速度和加速度,而该级数和可用一个解析式来表达,并近似为车速的线性函数。分析表明增加多轴车辆的轴数可有效地抑制车架和悬架的动载荷,但是随着车速的增加,抑制效果不断降低,直至相当于单轴车辆。更多还原

【Abstract】 Considering the incompressibility of fluid,the vertical velocity and acceleration of multi-axle vehicle with hydraulic suspension caused by road roughness can be expressed by a trigonometric series with phase angle as argument,and the sum of series can be reduced to an analytic formula,which approximates to the linear function of vehicle speed.Analyses show that increasing the axle number of multi-axle vehicle can effectively suppress the dynamic load on frame and suspension,but with the increase of vehicle speed the suppression effect constantly weakens and finally the vehicle behaves as a singular axle one.更多还原
