This schema is different. This is a five arms device with a locking mechanism to lock and unlock the weights during the rotation. After the starting and the first impact the falling of the weights are controlled.

You have one mass lifting three. It will rotate CCW after the mass falls.
re: I'd like to know your important opinion about my wheel
pequaide, could be.
It depends the impulsive force of the impact and how many arms the device is. I make simulation up to 16 arms and this case the wheel is pretty balanced e then require "less" energy to counter the unbalancing.
I hope to post the video.

re: I'd like to know your important opinion about my wheel
what program are you making the simulation in?
re: I'd like to know your important opinion about my wheel
Classic WM2D trial! I know that could give anomalous calculation :(
I'll try with any kind of 3D FEA software, but the better choice is always to buld a real prototype.

You are sliding one sphere and allowing it to secure motion. You then transfer that motion to the other 4 (or 15) spheres. You must intuitively think that this motion transfer will give you enough energy to get you over the top: the top being the imbalance caused by the dropped sphere losing its position.
Actually it is the opposite: when the motion of the moving sphere is transfer to the other 4 spheres the energy of the system goes down. Because we know from experiments that the motion transfer will conserve momentum. One sphere moving 5 m/sec is more energy than 5 spheres moving 1 m/sec (or 16 spheres moving .3125 m/sec). You need to transfer the motion of 5 spheres to one sphere not the other way around.
Wrap the five spheres with a string and then throw out the one sphere on the end of the string. All the motion will be transferred to the one sphere, and the energy increase will be significant.
Suppose you have a ten kilogram rim mass wheel that has a 100 meter string wrapped around its circumference. The rim is vertically mounted and its axle is resting in dry ice. You suspend one kilogram from the string and you allow it to drop the 100 meters. What is the circumference velocity of the wheel after the 1 kilogram has dropped 100 meters. What is the final RPM if the wheel has a diameter of 1 meter?
What happens if you move the string with the one kilogram to an attached pulley one tenth the distance from the axis to the circumference? You again drop the one kilogram 100 meters. What is the final RPM?

Take your design and draw a line from the 6 o'clock and the 12 o'clock. Count your weights on each side. Now draw a line from the 3 o'clock and the 9 o'clock. Now there are 2 quick ways to look at a design and here is what to look for. Is there more weight on the ascending side? On the second look, is there more weight under the 3 to 9 mark? If you answer yes to any one of these questions. There is a provable problems with the design. But there are possible exceptions due to possible reactions.
Good luck

re: I'd like to know your important opinion about my wheel
This is the working concept of my wheel:

Notice that there is not a control on the target bodies so the sliding weight stop.
I repeat, I do not know if the software calculation are correct!

This video shows a sixteen arms rotating device. The weights are controlled by lock/unlock mechanism

Even the best materials only give you a bounce of 90% or so and you have two bounces, and the sphere still goes back to the top?
Why are people not interested in what actually work?

re: I'd like to know your important opinion about my wheel
pequaide which you wrote is true.
But there are two important points to evaluate IMO:
1) the bounce decreases energy to the system, then limiting the bounce ...
2) shorter is the time the bodies are in contact more impulsive force can be transmitted to the rotating system and this impulse could rotate the system
Anyway these are speculation only. A real prototype should be built.
