The advantages of spring clip
2021-10-08
The elastic bar works under repeated alternating stresses.It bears various effects such as bending,torsion,fatigue and corrosion.When the vehicle passes,it also bears extremely high instantaneous impact load,so the performance requirements of the elastic bar are very strict. Play article USES the bending deformation of material performance at work,and USES the torsional deformation of material properties(especially the circular cross section),and generally good elasticity and basically no section weakened at the same time,so the material utilization rate is higher,on a routine,usually want to withhold a buckle under pressure,good elasticity,this article elastic fasteners has obvious superiority. China is a country with a wide range of fields,very different climate,transportation conditions and regions,so it needs a variety of cartridges with different performance requirements to meet the requirements of different tracks and different track types.For example,in the conventional line,it is necessary to buckle the spring bar with large pressure and good elasticity to meet the needs of heavy load and high-speed line;However,in the viaduct seamless track line,in order to reduce the interaction between rail and bridge,it is required that the resistance of the fastener is small,and ensure that the elastic bar has enough elasticity,that is,ensure that the elastic bar has enough low degree of steel,so as to ensure that the buckle pressure loss caused by the compression of the rail underlayer when the train passes is small,and the fastener is not loose.
