10 5 1 Dynamic Load Factor

If t d /T 1 then the dynamic load factor f dyn oscillates around the value 1 The duration t d of the force is relatively long compared to the period T of the system so much dynamic effects show up For 0 4 t d /T 1 the dynamic load is more severe than the static load The increase will be about 25% at most

Method for Calculating Moment Loads on Linear Actuators

While the actuator is operating moment loads occur due to not only gravity but also because of acceleration and deceleration of the load Because moment loads can damage actuators confirming that they are within specification is critical However calculating moment loads on linear actuators can be complicated and time consuming

Equivalent Bearing Load

If the bearing is subjected to a radial load solely then P=Fr For deep groove ball bearings it appears that P=Fr as long as Fa/Fre where Fa being the axial load and Fr the radial load If Fa/Fre then the equivalent bearing load P is calculated using P=XFr+YFa where X and Y depend on the type of bearing

What Is the Difference Between Static and Dynamic

Static loads differ from dynamic loads in the fact that the force exerted by the static load remains constant With a dynamic load the forces associated with the load change according to outside circumstances Static Load vs Dynamic Load The main difference between a static and dynamic load lies in the forces produced by the weight of an object

Calculating Feeds and Speeds

When calculating the feed rate for any material the chip load is therefore one of the most important factors to be taken into account because the chip load determines the amount of material that each tooth will remove plus the load that each tooth will have to take Another factor that affects chip load is the diameter of the cutter
