Bistable prestressed spring steel grippers for aerial perching and grasping
… gap in research through the use of prestressed spring steel bands (PSSB) to create compliant bistable grippers for aerial perching and grasping. We investigate multiple different PSSB configurations. We first investigate two single PSSB gripper designs, a single band gripper with a cable driven …

A flexible crampon design
… the crampon itself is flexible, being made from spring steel. This allows the crampon to flex with a hiker's foot, thereby improving walking comfort.

Vibration-to-electric energy conversion using a mechanically-varied capacitor
… AC capacitance, formed by a 43.56 cm2 spring steel top plate attached to an aluminum base, drives the experimental charge pump near 1.56 kHz. HSPICE simulation confirms that given a maximum to minimum capacitance ratio larger than 1.65 and realistic models for the transistor and diodes, …

Development of a low-cost high-impact resistant compliant myoelectric prosthetic hand
… follower link with three layers of pre-stressed spring steel. This design behaves like a conventional four-bar linkage but adds lateral compliance and eliminates a pin joint, which is a main site of failure on impact. We introduce the fabrication process of the compliant finger and palm that …

Design and modelling of ultra-high strength steels: nanoprecipitation and plasticity
… research was to develop new ultra-high strength steels via nanoprecipitation control, which requires an understanding of the processing-microstructure-property relationship in medium carbon (0.5-0.6 wt.%) steels throughout tempering. Much of the work has been centred in understanding the role of …

A study of the microstructural and mechanical properties of novel spring steels.
This work is concerned with track spring components manufactured by Pandrol from a SiMn alloy in the quenched and tempered condition. For many years low to medium carbon based spring steel has been manufactured via an oil quench temper route producing components with suitable mechanical and …

Analysis and design of rapid prototyped mechanisms using hybrid flexural pivots
… performance metals such as stainless and alloyed steel or aluminum alloys for high material performance and durability. Functional requirements such as high bandwidth, accuracy performance and geometric complexity require them to be manufactured as monolithic structures using conventional …

Experimental and theoretical studies of corrosion fatigue in a high strength steel.
… aspects of corrosion fatigue in a high strength steel. Fatigue tests were conducted under fully reversed shear loading in an aerated 0.6M NaC1 solution at pH6, for a silico-manganese spring steel (BS251A58) having a yield strength around 1400 MPa. The fatigue crack evolution process can be …
