The studes on adjustment torsional rigidity of torsion bar;

This article simplely introduced torsion pendulum's parameters, and practial tested torsional rigidity of slivers.

The lateral rigidity and torsional rigidity of the wall is enhanced and the pertinence contexture is strengthened by configuring of vertical structure rationally and after the actual analysis and calculation for the specific project.

For a multi-cracked prismatic shaft torsion problem example,an optimized project of Back-propagation training is introduced by using Neural Network toolbox in MATLAB software,and the project is explained in detail and the good learning scheme is given by simulating the experimental results of the torsion rigidity.

Torsional stiffness of tower crane mast is closely related with the arrangement of Web members of the mast.

In this paper,the prestressing scheme of back diagonals of large miter gates and its analysis technique are discussed,and in connection with some conventional types of miter gates,the torsional stiffness,steel consumption and usage factors are investigated and compared.

Based on the analysis of the experiment,it studied the deformation capacity of the SRC in a state of pure torsion,and further discussed the impact of component factors of torsional stiffness.

Then relative twisting angle and twisting stiffness of soft wire shaft are obtained.
