So the travelling speed of stress wave can be obtained.
从而得到应力波的传播速率。
Based on result of calculation, proposal is made to limit the maximum travelling speed of the crane and the speed with which the crane can run on a curve with small radius.
根据计算结果对该起重机最高行驶速度和通过小半径曲线的速度限制提出了建议。
The increase of lifting speed and trolley travelling speed have raised handling efficiency.
