shake tables

For earthquake simulations, one of the services we provide are shake tables. Currently, there are two, relocatable, 7.0m x 7.0m platforms with six-degrees of freedom. Each table is capable of 50 tons payload. A 3.6 x 3.6 meter table platform of welded steel construction with a weight of

Shake Tables The shake table systems produced by BISS are being widely used in testing structures or components of civil or automotive or aerospace or nuclear power engineering. These systems are typically used in testing structures subjected to random or periodic support excitations for understanding their dynamic behavior or for their

VIBRATION & SHAKE TABLES. Single- & multi-degree-of-freedom servohydraulic vibration testing systems. These sysetms typically offer longer stroke and better low-frequency test

The Shake Table’s motor is a 400W high-powered 3-phase brushless DC actuator. The motor contains an embedded high-resolution encoder that allows the position of the stage to be measured with an effective linear resolution of 1.55 μm. An analog accelerometer mounted on the Shake Table II platform measures the acceleration of the stage directly

Electric Shake Tables. Use ANCO’s multi-axes, all electric, servo-motor driven shake tables for small to medium test items when the following are particularly important: Quiet table operation. Preference for electrical over servo hydraulic systems. Low maintenance. Higher frequency range. The table

This resource is a guide for running a shake table workshop with your students, using simple materials to build small scale shake platforms and towers that represent how engineers and scientists test building structures under earthquake-like conditions. Engineers usually test structures until they reach seismic failure (i.e. collapse at different degrees of movement) and they analyse data to

Our thin shake tables and light, portable bench top shakers are typically part of the vibration test equipment used in educational, research and laboratory environments. From light to heavy loads and small to large test items, our shakers and vibration platforms can handle it all. We can even produce platform shakers with as much as 800lb force

The RP-4 shaker table is the most widely used and most successful gold gravity shaking concentrating table worldwide, used by small and large mining operations and the hobbyist. The patented RP-4 is designed for separation of heavy mineral and gemstone concentrate. The RP-4 table can process up to 600 (typically 400) lbs. per hour of black sand

armature to shake platform (Fig. 14). Note the twist in the armature for strength. Step 3: Lock hex bolt in electric drill.-----Figures 15 and 16 show the final product. When using the shake table, secure it to the table it is resting on using clamps. This will prevent the shake table from walking when the drill is at high RPMs

Shake table tests provide a true representation of seismic phenomena including a fully dynamic environment with base excitation of the test structure. For this rea-son shake tables have become a staple in many earthquake engineering laboratories. While shake tables are widely used for research and commercial applications, further

Mar 29, 2019 The table itself can displace +/- 350mm, with a maximum velocity of 75 cm/s. The dynamic actuator has a maximum pushing force of 260 kN. The shake table is displacement controlled and the earthquake ground motion is put in as a displacement command signal

The shaking table they created is the same one operated by PEER today and is still the largest multidirectional shaking table in the United States and among the most sophisticated in the world. Many of the design features originated in Berkeley, were later adopted for shaking tables in Japan, Mexico, Peru, and Yugoslavia

The two-story test structure was tested on a shake table at the Multi-functional Shaking Tables Lab of Tongji University in Shanghai, China. The shake table has an overall table dimension of 6 m 4 m, maximum payload capacity of 700 kN, operational frequency range 0.1–50 Hz, PGA of 1.5 g and displacement range of +/-500 mm

The shake table systems produced by BISS are being widely used in testing structures or components of civil or automotive or aerospace or nuclear power engineering. These systems are typically used in testing structures subjected to random or periodic support excitations for understanding their dynamic behavior or for their performance evaluation. The payload rating of BISS shake tables vary from 50 kg to 5000kg
