Circular cam-roller (CCR) quasi-zero stiffness (QZS) vibration isolators have been
extensively studied. As the CCR isolator can only achieve low stiffness in a very small range …

A semi-active electromagnetic quasi-zero-stiffness (QZS) vibration isolator (VI)(SEQZS VI) is
proposed to broaden the frequency bandwidth for low or ultra-low frequency vibration …

To overcome the limitations of linear series elastic actuators (SEAs) with constant stiffness, a
novel load-adaptive actuator with variable stiffness is proposed for actuating ankle …

Inspired by the strong nonlinearity of origami cartons, a novel origami-inspired constant-
force mechanism (OriCFM) is systematically studied for obtaining a stable quasi-static …

The realizing of variable output constant force has received wide attention. To achieve a
force regulation in an economic way, a configuration of the constant force mechanism (CFM) …

In order to enlarge the proportion of constant-torque output, a new type of constant-torque
flexure hinge based on line-arc-line segment (LAL-CTFH) is designed. The LAL-CTFH has …

The potential applications of constant-force mechanisms (CFMs) have increased in recent
years with the development of new designs. This paper focuses on the experimental …

The concept of a statically balanced mechanism with a single rotational degree-of-freedom
is presented. The proposed device achieves static balancing by combining positive stiffness …

Dynamic constant-force performance is essential in suspended astronaut micro-gravity
simulation systems. Of particular concern is the active constant-force system comprising a …

Constant-force mechanisms (CFMs) can produce an almost invariant output force over a
limited range of input displacement. Without using additional sensor and force controller …
