第二讲转鼓运动学当土壤稳定机械作业时,它的工作机构——转鼓完成着一种复合的运动,它由转鼓绕其轴线旋转的相对运动和轴线自身移动的牵连运动所组成。在稳定工作的条件下(即转鼓的角速度ω和转鼓轴线移动的线速度V为一常值),转鼓上不同半径点所画出的运动轨迹是一组长短幅旋轮线。在半径r_i=v/ω上的各点所作的是旋轮线,r_iv/ω上的各点画出的则是长幅旋轮线转鼓上各点的运动轨迹 1、刀尖上的轨迹由于刀尖点的半径R总是大于v/ω,所以它画出为一幅旋轮线。其轨迹的参数方程可以表达如下: x=v/ω(θ)±Rcosθ=Vt±Rcos ωt(1) y=Rsinθ=Rsinωt式中θ=ωt——刀尖向径R相对X轴的转动角度; t——向径R转过0角所需时间;
Lesson 2 Tumble Kinematics When the soil stabilizing machine is in operation, its working mechanism, the tumbler, completes a complex movement consisting of the relative motion of the drum rotating about its axis and the implicated movement of the axis itself. . Under stable operating conditions (ie, the angular velocity of the drum ω and the linear velocity of the drum axis moving V is a constant value), the trajectories drawn at different radius points on the drum are a series of long and short spiral wheels. Each point on the radius r_i=v/ω is a spiral line. Each point on r_iv/ω is a long one. The trajectory of each point on the rotary drum line drum 1. The trajectory on the blade tip Since the radius R of the tool tip point is always greater than v/ω, it is drawn as a rotary wheel line. The parametric equation of its trajectory can be expressed as follows: x=v/ω(θ)±Rcosθ=Vt±Rcos ωt(1) y=Rsinθ=Rsinωt Where θ=ωt is the angle of rotation of the tool nose radius R with respect to the X axis. t - the time required to turn 0 degrees toward R;
