A Calculation Method Based on Tension Distribution and Temperature Compensation for Sliding Cables

Abstract:

The calculation of sliding cable is difficult because it can dynamically pass through prescribed nodes and the length is variable. In order to solve the above problem, a calculation method based on tension distribution and temperature compensation for sliding cables was put forward. At first, the sliding cable was supposed to be fixed cable and the internal force of each cable segment was calculated. Then, the unbalanced tensions between neighboring cable segments were distributed to make the tensions equal. And then different temperatures were applied to the corresponding cable segments, which could cause temperature stress to compensate the unbalanced tensions between the initial calculated tensions and distributed tensions. At last the calculation was carried on again after applying the temperature to each cable segment. Moreover, an example was presented to verify the precision and validity of this method. The results show that the calculation method based on tension distribution and temperature compensation for sliding cables is effective.
