The system can effectively and continuously measure the boom's rotation angle and tilt angle, and the force exerted on the supporting leg when there are certain loads on the boom. 该系统能够有效连续地测量车辆在吊臂或支臂承载一定载荷时的臂架旋转角度和倾斜角度以及支腿的受力情况。
Load, boom angle, and other indicators over their full range, for any significant inaccuracies. 由于任何明显的误差负荷、吊臂或其它指示仪超过其最大范围。
The technique was applied to a simulated model of a boom crane slewing at a constant luff angle while reeling in the cable and linearized around the payload equilibrium position. 传送时间由叠代减到最小技术被申请了于旋转在一个恒定的逆风行驶角度的景气起重机的一个被模仿的模型,当卷在缆绳时并且在酬载平衡位置附近线性化了。
And with ballast moving with the hoist boom, safety is greatly enhanced, but sensors are required to measure the weight and the boom angle so that the structure becomes complicate and the cost is high. 配重与吊臂联动时,安全性大为提高,但需要传感器实时测出起重量和吊臂角度,使得整车的结构复杂,成本上升。
First, we can obtain boom amplitude angle and tower crane basement angle of two cranes by means of absolute encoder. Then, we use projection method for establishment of two-dimensional projection model of crane, and so as to analysis four-quadrant double-arm anti-collision problem. 通过绝对编码器我们可以获得两台起重机的臂架幅度角与塔基旋转角度,然后,运用投影法建立起重机的二维投影模型,分析四象限双臂防碰撞的问题。
The test result showed that the boom conversion mechanism could complete the movement of boom lift and angle change, so the boom sprayer and the tunnel sprayer could be transformed automatically, and the design is feasible. 试验结果表明:喷杆转换机构物理样机能够完成喷杆自动升降和喷杆变角的动作,实现喷杆式与隧道式机构的转换,机构设计方案可行。
As a result, when the boom is comparatively short or the initial luffing angle is small, calculating efficiency can be improved by the replace of nonlinear model by using the linear one. 因此,在臂长较短或者臂长较长初始变幅角较小时,可用线性模型代替非线性模型,以提高计算效率。
