The Modal Shop’s modal shakers are a proven solution in test laboratories around the world. With force ratings from 4.5 to 100 lbf (20 to 440 N), these shakers are suitable for a wide range of modal analysis applications. When performing experimental modal analysis and structural testing, the choice of excitation function and system will make the difference between a good measurement and a poor one. For many applications, an electrodynamic shaker system is the ideal choice. The Modal Shop’s line of modal shakers is designed to be highly portable, rugged and easy to set up in order to facilitate the best testing results. The exciter size allows a diversity of placement locations relative to the test structure, while minimizing any unwanted interaction between the exciter and test structure.

Your product descElectrodynamic shakers makes use of an electro-mechanical assembly to product vibration through electromagnetic force. These electrodynamic shaker systems can precisely generate either single, or multi-axis vibration using sine, random, sine-on-random, or random-on-random accounts. Usually these ED shakers are utilized to figure out the products ability to either run within it’s intended environment, or to target resonance in the product to determine weakness.Any type of product moved by road, sea or air, is subjected to vibration tests throughout its manufacturing procedure. These tests supply essential details relating to the behavior of the manufactured part before advertising and marketing, in order to prevent them breaking in the future.All the vibration tests, both vertical and also horizontal, may furthermore go through temperature as well as relative humidity tests, integrating the vibration test with making use of a climatic chamber. The electro dynamic shakers from Wewon attach to any kind of electrodynamic vibration system. https://www.wewontech.com/electrodynamic-shakers/

Environmental Vibration Testing
-
Whether for independent monitoring or just adding additional channels to an existing vibration controller, the m+p Analyzer real time analyzer provides an ideal solution for measuring vibration and other responses during a shaker test or with shock machines. All test modes allow in-parallel throughput to disk recording so that the raw sample data is available for post-test analysis.

Squeak & Rattle Sub-System And Component Testing
-
At MB Dynamics, we’re proud to provide clients in a wide range of industries with quiet, custom turnkey component testing systems for combined squeak & rattle testing as well as durability testing of different components and subsystems (in 1 to 6 DOF). Test items can be excited in one or more axes to understand and characterize the physics and root causes of BSRs. Real-world, on-road vibration conditions are multi-axis simultaneous – vertical, fore-aft or longitudinal, lateral, roll, pitch, and yaw – 6 degrees of freedom or 6 DOF. Affordability drives decisions to find BSRs by exciting in one or two – fewer than 6 DOF. That has been a driving force for MB – be effective at finding BSRs with a lesser number of shakers (DOFs) and thus reduce the test equipment cost of finding BSRs. Vertical-only can be effective; sequential vertical then fore-aft then lateral is one step closer to real-world; creating vibration in four or five axes of response simultaneously is even closer; and full 6 DOF systems that are quiet come closest to duplicating in the lab the on-road conditions. MB offers all these possibilities to meet trade-offs of budget, test time, road replication, and BSR detection effectiveness.

MSP-Series Screw Presenters
-
The MSP is a small, tabletop screw presenters used to organize and automate work areas and production cells. Screw presenters make assemblers and the assembly process more efficient by mechanically presenting a screw to a fixed pick up point. Conventional assembly methods cause assemblers to inefficiently fumble with screws that are stored in bins or shaker trays. The enhancement of productivity is estimated to improve assembly time by nearly fifty percent. The inexpensive screw presenter is an alternative tool instead of the cumbersome and very expensive screwfeeder systems.
