In summary, to design an orbital shaking platform with a pitch of 20 mm and a shaking speed of up to 300RPM (extended range 500 RPM), with a platform size of 525mm x 525mm and capable of carrying loads of up to 10 Kg, you will need to first select a suitable drive system such as an induction motor with a gearbox or a servo motor and drive. Then, you will need to calculate the forces acting on the system, including the weight of the platform and the forces from the shaking motion, to determine the appropriate size and strength of components such as bearings, shafts, and gears. Next, you will need to calculate the motion of the platform, including velocity and acceleration, and

i need help designing a orbital shaking platform with a pitch of 20 mm, shaking at speed of upto 300RPM (extended range 500 RPM) with platform size of 525mm x 525 mm, capable of carrying loads of upto 10 Kg without considering the weight of platform itself.

How to undertake mechanical calculations considering forces etc to derive a strong drive and system components like bearing sizes, shaft sizes, motor power etc

Unit needs to run on induction gear motor

basic idea is as shown in the picture attached having counterbalanced triple eccentric drive

mechanism. 1. Selection of drive system: First, you will need to select a drive system which is capable of providing the desired performance. This could include an induction motor with a gearbox, or a servo motor and drive. Once you have selected the drive system, you must then select components such as bearings, shafts, and gears which are suitable for the application. 2. Calculating forces: You will also need to calculate the forces acting on the system. This includes the force of gravity, the weight of the platform, and any forces due to the shaking motion. You can use these forces to calculate the size and strength of the components needed. 3. Calculating the motion: You will need to calculate the motion of the platform in order to ensure that it meets the desired specifications. This will involve calculating the velocity and acceleration of the platform, as well as the angular velocity and acceleration. 4. Design verification: Once you have designed the system, you must verify that it meets the desired specifications. This can be done using simulations or by testing the system in actual conditions. 5. Finishing touches: Finally, you must make sure the system is safe and reliable. This includes selecting appropriate materials for the components, checking for any potential failure modes, and making sure the system is properly lubricated.
 

1. What is an orbital shaking platform?

An orbital shaking platform is a laboratory instrument used to mix, shake, or stir samples placed on it in a circular motion. It is commonly used in biological, chemical, and medical research to facilitate reactions or to keep samples in suspension.

2. How does an orbital shaking platform work?

An orbital shaking platform consists of a flat platform that moves in a circular motion using an orbital drive mechanism. The motion can be controlled through speed and duration settings. The platform also has clamps or holders to secure the samples in place. As the platform moves, it causes the samples to move in a circular motion, creating a vortex-like effect that mixes the samples.

3. What are the benefits of using an orbital shaking platform?

An orbital shaking platform offers several benefits, including efficient mixing of samples, increased reaction rates, and uniform distribution of solutes. It also helps to decrease the time and effort required for manual mixing, and some platforms can accommodate multiple samples simultaneously, increasing productivity in the laboratory.

4. What types of samples can be used on an orbital shaking platform?

Orbital shaking platforms can accommodate a wide range of samples, from small test tubes and vials to large culture flasks and bottles. They are commonly used for mixing liquids, suspensions, and emulsions, but some platforms also have attachments for mixing solid samples.

5. Are there any safety considerations when using an orbital shaking platform?

While orbital shaking platforms are generally safe to use, there are a few safety considerations to keep in mind. It is essential to secure the samples properly to prevent spills or breakage. Also, ensure that the platform is placed on a stable and level surface and that the speed and duration settings are appropriate for the samples being used. Always follow the manufacturer's instructions and wear appropriate personal protective equipment when handling hazardous materials.
