Spinning technology also has a high material utilization, high efficiency, low energy consumption characteristics.
There have simulations on brake jitter by ADAMS software in civil [1] and many test reports on brake jitter [2] .Spinning brake cylinder is a key component of brake system in the train.
The friction between the piston rod and dust blankets put on the front cover is one of the reasons causing jitter, felt the material indicated on the drawings as “industrial felt 112”, this blanket is divided into several different grades according to density, density maximum of kg/cm2, the smallest of kg/cm2.

Axial capacity of steel angles with local deformation Jian Xie 1,2, a, Xiaodan Han1,b and Anxiang Ge1,c 1 Department of Civil Engineering, Tianjin University, China 2 Key Laboratory of Coast Civil Structure Safety, Ministry of Education, Tianjin University, China axiejian@tju.edu.cn, bHanxd_tju@163.com, cgeanxiang05@163.com Keywords: single equal-leg angle, test, finite element analysis, axial capacity, compression, tension Abstract.
Nonlinearities relating to geometric and material characteristics were considered and steel stress-strain relationship was assumed to be elastic-perfectly plastic [11].
The failure of specimens subjected to axial tension load is mostly caused by material failure.
