The current research mainly focuses on the flow control for the two-stage proportional valve
with hydraulic position feedback which is named as Valvistor valve. Essentially, the Valvistor …

To meet the vibration isolation requirements, the twins torsion spring is placed between the
pivot and the clutch, which can make the generator and front gear train run more stably, and …

This work aimed to identify and evaluate the reasons that led to a compression spring to fail.
The compression spring was operating in a wagon torpedo, a vehicle that transported pig …

In this work, the failure mechanism of four high-strength valve springs were investigated. It
shows that the premature fatigue failure of valve spring can be attributed to the presence of …

Abstract Design of helical springs are well defined and studied thoroughly. Generally,
behavior of stiffness is considered to be in linear regime with desired dimensions. However …

In the current study, the problem of cracking on the stop valve body in a steam turbine
related to a thermal power plant is assessed. The problem usually occurs consecutively and …

The torsion spring is an important component for vehicle steering system. The torsion spring
in this study was manufactured using high quality carbon structural steel. In order to study …

Composite solid propellant will inevitably experience long-term loading environments in
aerospace structures and weaponry applications. However, failure modes such as delayed …

This study investigates the fatigue failure behavior of coil compression springs and various
influencing factors. The intrinsic and induced causes of fatigue failure in metro steel springs …

The intension of this work is to conduct a failure analysis and optimize the design of the shaft
in a 4.5 KW alternator used in rail coaches. The shafts in alternator of rail coaches are …
