在车辆结构中,通常假设杆件端部的削度为无限大,本文将这种假设变为适合Cross法的形式,并用一著名的公式来确定这些被假设为非弹性部分的长度。此外还指出,在计算框架时,应如何校正个别杆件惯性矩的变化。在处理桔构不对称的车体时,由于进一步采纳了合理的建议,所以能此较简单地提出平衡条件。这些平衡条件均可由杆件端部力矩总和来表示。文中并举例能明该法的实际应用。
In the vehicle structure, it is usually assumed that the bar end is taped to infinity. This article makes this assumption a form suitable for the Cross method and uses a well-known formula to determine the lengths of these assumed as inelastic parts. In addition, it is pointed out that how to correct the change of moment of inertia of individual bars when calculating the frame. In dealing with asymmetric orange body structure, due to the further adoption of a reasonable proposal, it can be more simple to put forward the balance of conditions. These equilibrium conditions can be expressed by the sum of the moments at the end of the bar. The text and examples to illustrate the practical application of the law.
