Problems solved by technology

however, current kinetic energy absorption solutions are highly susceptible to failure, in part due to the insufficient degree of vibration damping provided
Other kinetic energy absorption schemes may only provide a constant degree of kinetic energy absorption and therefore cannot adapt vibration damping to changing environments
[0007] However, in a mobile environment, the acceleration forces applied to the payload vary with time, making static energy absorption schemes largely inefficient

Embodiment Construction

[0017] In general, various embodiments of the invention are used to protect payloads in mobile and / or non-mobile environments. In particular, in various embodiments, various payloads are provided with kinetic energy transfer protection, and the multi-axis adaptive suspension is thus used to protect the payload from potentially disruptive acceleration forces.

[0018] Multi-axle suspension systems usually offer various modes of adaptation. In a first adaptive mode, the multi-axis suspension system provides weight adaptation to maintain the position of the payload relative to the equilibrium position of the payload between the first and second positions by applying a force opposing the weight. Thus, regardless of the weight of the payload, the equilibrium position of the payload is always maintained substantially between the first and second critical positions.

[0019] In a second adaptive mode, the multi-axis suspension system provides acceleration adaptation, whereby multi-d...

Abstract

A method and apparatus for an adaptive, multi-axis suspension support system providing both coarse and fine suspension to a payload. Coarse suspension control is provided to maintain the payload within a coarse range of position. Fine suspension control is provided by monitoring and analyzing vibration characteristics in both time and frequency domains to determine the required amount of damper resistance to be exerted by a magnetorheological (MR) device.

Description

technical field [0001] The present invention relates generally to suspension support systems, and more particularly to adaptive suspension support systems. Background technique [0002] Mobility has permeated every aspect of life since the invention of the wheel. From ancient animal-drawn carts and trailers to today's state-of-the-art transportation vehicles, literally millions of people depend on mobility in their everyday lives. For example, mobility provides a faster and more efficient mode of work, thereby creating more activities closely related to productive work and more interesting leisure activities. [0003] The wheel remains one of the most widely used mechanisms for facilitating modern means of transportation, while others have also emerged, such as aerodynamic lift and jet propulsion. In general, all modes of transportation arise from the need to move payloads from one place to another. The payload to be transported can be an animate object (such as a human b...
