摘要
复合材料具有高强度-重量比和高刚度-重量比,它用于步行车辆结构设计可减轻相对运动部件的重量,降低能量消耗,抑制弹性振动.本文利用动力学虚功原理建立了具有复合材料构件步行车辆系统的动力学有限元模型,对四足步行车辆模型进行了模拟计算,以说明使用复合材料的优越性.
Composite materials possess much higher strength-to-weight ratios and stiffness-to-weight ratios than the commercial metals. The use of composite materials in the design of legged vehicles may reduce the weight of moving members,decrease the power consumption,and dissipate the flexible vibration. A general approach,based on the finite element method, is presented for dynamic analysis of legged vehicle with composite material components. The numerical example for a quadruped vehicle is presented in order to demonstrate the effect of the use of the composite materials.
