چکیده
The traditional low-alloy steel rose-bow spring of subway pantograph is easily occurred the corrosion and fracture after being used for a central period time, which interrupts train current collection cannot provide power train, as result interruption normal operation trains. Therefore, an optimal design improved processing technology titanium alloy was studied in this paper. heat treatment tests on two springs, made TC18 TB6 materials, were conducted respectively. process flow also determined. Fatigue test results show that both springs can meet corresponding requirements.

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
