Abstract

A vibration isolator of the type used for mounting industrial equipment, having the capability of measuring forces exerted upon the isolator to adjust the support provided by each of the isolators upon which the equipment is mounted so as to provide the most suitable distribution of support and to reduce the transmission of dynamic forces created by the operation of the equipment. The isolator comprises a resilient base, a bearing plate on the base and a sensing device cooperating therewith, with or without means for attaching the isolator to the equipment. A force applied to the isolator exerts pressure on the bearing plate which is transmitted therethrough to the resilient base causing each of them to experience some deformation. The sensing device detects the pressure or deformation caused by the force applied to the isolator and generates a signal corresponding to said force. The signal is transmitted to indicating instruments suitably calibrated to show the static and dynamic forces to which both the equipment and foundation are subjected, as well as the weight and center of gravity of the equipment.

Claims

1. The method of optimizing the weight distribution, balance and performance of an operable machine which comprises mounting same on a plurality of height-adjustable, load-indicating, vibration-isolating supports and thereafter selectively adjusting the height of each such support while observing indications of load thereon so as to equalize weight distribution, then placing such machine in operation, observing variations in load indications during such operation and selectively adjusting the height of any such supports as necessary to distribute weight for optimum stability consonant with the cyclical dynamics during operation of such machine.

2. The method of optimizing the weight distribution, balance and performance of an operable machine which comprises mounting same on a plurality of height-adjustable, load-indicating vibration-isolating supports and thereafter selectively adjusting the height of each such support while observing indications of load thereon so as to apportion weight for preliminary leveling, then placing such machine in operation, observing variations in load indications during such operation and selectively adjusting the height of any such supports as necessary to distribute weight for optimum stability consonant with the cyclical dynamics during operation of such machine.
