..., and thicknesses of its flexures) so that the mechanism achieves the exact transmission ratio desired once a material has been assigned using stiffness matrices. The transmission mechanism of Fig. 2( h ) can be schematically simplified to a one-dimensional series of springs and rigid bodies as shown in Fig...

... using all joint information is further developed in this paper, as well as the involved elastic system. This approach with considerable compensation effect is simple in principle, and the ZFL property is precisely and completely realized by commercial springs. Compared with the previous method...

... demonstrated that the proposed mechanism, combining self-excited vibrations by magnetic nonlinear springs and one-way clutches, achieves the desired behavior based on the PDT principle and is capable of power transmission at several velocity ratios and rotational speeds. In particular, performance evaluations...

...Juan M. Munoz-Guijosa; Alejandro Silva; Cristina Alén-Cordero; Álvaro Guzmán Due to their robustness, compactness, simplicity, and the possibility of nonlinear torque curves, spiral springs are being increasingly contemplated for industrial application. Recent manufacturing technologies...

... synthesis Compliant mechanisms Design validation Mechanism theory Springs Multistable mechanisms are mechanical devices with more than one stable state. A stable state is the deformation of the mechanism at which its energy is minimum, implying that a zero force is required for maintaining...

... is exploited. To this end, two conical springs are specially sized to provide the nonlinearity. To eliminate the linear stiffness, the concept of a negative stiffness mechanism is implemented by two cylindrical compression springs. A small-sized NES system is then developed. To validate the concept...

...Manuel Paredes Cylindrical compression springs have been commonly exploited in mechanical systems for years and their behavior is considered as well identified. Nevertheless, it appears that, even though old research studies suggest correcting the rate formula, the main industrial software...

... arm mechanisms have reached fairly broad adoption over a range of applications, it remains unknown exactly how the spring properties and geometric parameters of the mechanism enable its overall performance. We developed a simplified model to analyze the vertical dynamics of stabilizing arms...

...Manuel Paredes Now the transition load P T and the maximum load P M can be calculated. P T is the load from which the spring starts to come to solid (when D L  =  D 2 ). P M is the load when all the coils come to solid (when D L  =  D 1 ) P T = π tan α Gd...
