I want expert in matlab simulink to simulate the pneumatic pusher rod system from mandrel and optimize the design based on result so that rod comes out from mandrel smoothly. If anyone has any method or idea to do the same task fast please include that.

I am looking for an expert in Matlab Simulink who can simulate and optimize a pneumatic pusher rod system. The desired outcome of the simulation and optimization is to achieve a smooth rod extraction from the mandrel. I am open to any design that can achieve this outcome.

Requirements:
- Expertise in Matlab Simulink
- Experience in simulating and optimizing pneumatic systems
- Ability to analyze and optimize the design based on the simulation results
- Strong problem-solving skills

Deliverables:
- Detailed report with graphics and mathematical analysis
- Simulation results and optimization recommendations

If you have any methods or ideas to expedite the task, please include them in your proposal.
