| The full name of the electrostatic particle accelerator is the charged particle accelerator.As its name suggests,it is an apparatus that uses electromagnetic fields to accelerate charged particles.Electrostatic accelerator charged particles include electrons,protons,a-particles,and various ions.The accelerator transfers electromagnetic energy to the charged particles and accelerates the charged particles.Increased energy.The traditional electrostatic accelerator mainly uses the way of transmission belts and elevators to carry out the charge transmission.Its essence is belt transmission,which is easily affected by external humidity and temperature,and its transmission stability is not high.Because it can be driven under high temperature and heavy load,and its transmission efficiency is relatively high,slipping and other phenomena are not easy to occur,and it is decided to adopt the form of chain transmission to carry out charge transfer.On the basis of reading a large amount of related literature,this paper analyzes and summarizes the development and application status of electrostatic accelerators and chain drives at home and abroad,studies the working principle of electrostatic accelerators and the transmission mechanism of chain drives,and explains the significance of this study.The main objectives and research methods of the article.According to some basic parameters given,the transmission chain is calculated and preliminary designed.Through material comparison,select suitable insulator materials;design and calculate some key components such as transmission chain sensing electrodes and short-circuit current;select appropriate chain model and sprocket parameters by calculating and consulting the mechanical design manual;Analysis and calculation of motion characteristics,determination of basic motion parameters,and data foundation for the next simulation;Finally,using CATIA,CAD and other software for three-dimensional modeling and two-dimensional drawing output,according to simulation optimization results,modify the design parameters,and then proceed manufacture.The three-dimensional model created in CATIA software was imported into RECURDYN software to generate the sprocket flexible body,and then the constraints such as plane pair,rotation pair and driving force were added,and then the chain transmission system was carried out under different loads and under different working conditions.System dynamics simulation analysis.Through the simulation results,the movement characteristics of the transmission system in terms of displacement fluctuation,speed and force are analyzed.Then use the finite element analysis software ANSYS WORKBENCH to analyze the dynamic and static mechanics of the main components of the transmission system,and obtain the natural frequency and corresponding arrays of each order and the corresponding equivalent stress and strain distribution cloud map.Through the simulation results,verify whether the system can occur.Resonance and whether to meet the material’s strength and stiffness requirements.Finally,test verification analysis.Select a suitable motor,design a suitable rack size,and set up a test bench.Using a DC stabilized current source as the sensing electrode for operation,a displacement sensor is used to measure the amount of jitter in the transmission chain,and a speed sensor is used to measure the speed fluctuation of the transmission chain during the movement.The current of the uplink and the downlink are measured by an ammeter and the transmission efficiency is calculated.By measuring the change of the high voltage electrode with time,the transmission power can be calculated. |
