Shoulder exoskeleton is a popular solution to work-related shoulder disorders and muscle fatigue. With a wide range of exoskeletons designed, a comprehensive report on how the use of shoulder exoskeletons changes shoulder biomechanics is still missing. In this project, the impact of exoskeletons on shoulder biomechanics was investigated with the...

The recent success of - and demand for - compliant mechanisms has increased rapidly within the micro-electromechanical systems-, aircraft-, spacecraft-, surgical-, and precision-instrument industries. Yet, even greater success may be achieved by overcoming the computational cost and instability of the mechanisms' design methodology. This...

As mechanisms become increasingly precise, so becomes the reduction of noise and vibration increasingly important. One method for eliminating vibrations in mechanisms is dynamic balancing. This method prevents vibrations from occurring by designing the mechanism such that the inertial forces and moments of all bodies in the mechanism cancel each...

The range of motion of elastic energy sources is limited by the size of its transmission system. To enhance this range of motion without compromising the size, previous research introduced a frequency doubling mechanism with the intention to concatenate these mechanisms. This study serves to achieve higher numbers of frequency multiplication by...

Conventional hydrostatic bearings are not suited to use on surfaces with changing curvature which limits their applicability. To improve on this, deformable hydrostatic bearings are currently being researched. The goal of this work is to develop hydrostatic bearings with a single fluid supply that work for sinusoidal counter surfaces. <br/><br/...

Vibrations have been studied in various engineering fields due to their detrimental and even destructive effects on structures. Suppressing low-frequency vibrations has been a research challenge for decades and is mostly achieved by implementing active vibration control techniques. In the last two decades, the emergence of locally resonant...

This paper presents a validation of a parametric compliance matrix of a circularly curved leaf flexure (CCLF), which has been obtained using the direct method. This is done for three case studies. In case study one, the compliance matrix of a single flexure is evaluated. The results are compared with the results from a finite element analysis...

Industrial passive exoskeletons have been developed for years as a tool to reduce the physical workload of their users. They accomplish this by compensating for the user’s body weight and decreasing fatigue caused by repetitive loads. Despite their advantages, current exoskeletons have drawbacks that make them less convenient for users and thus...

Compliant mechanisms are often used in precision mechanism design as a suspension for translational stages. Their light weight makes them efficient and they do not suffer from friction or backlash. They transmit and transform a finite motion along their degrees of freedom via elastic deformation and provide high stiffness along their degrees of...

This work aims to achieve a softening moment-angle response by utilizing compliant parts. The approach uses the principle of contact release, which involves initially prestressed torsional bars arranged in series, separated by rigid bodies. By stepwise activation of the torsional bars, a softening behavior is achieved. Mechanical stops are...

Flexure mechanisms are widely utilized in precision mechanisms, but their practical use is limited by three major factors, namely restricted range of motion, parasitic motion, and significant reduction in support stiffness when deflected. To address this limitation, in this research the potential of variable thickness flexures in minimizing the...

The use of elastic frequency multipliers presents the ideal platform to address the coupling between the footprint and range of motion of elastic mechanisms. By transmitting unidirectional into reciprocating motion they efficiently increase the range of motion without a huge compromise in size. In this thesis, an elastic<br/>frequency doubler...
