Optimization Of Key Function Modules Of Ambulance

In all kinds of emergencies,the victims are in urgent need of efficient treatment and the help of ambulance.At this time,the ambulance is the savior of people in the disaster and the most important thing to save people’s lives.In this paper,the existing ambulances on the market are optimized to improve the rescue efficiency.There are many functional modules of the ambulance.In this paper,we choose the most important functional module of the ambulance to optimize the research,the main contents are as follows:(1)A new overall layout design of ambulance carriage is established,and the necessity of redesigning the overall layout of ambulance carriage is analyzed.This paper puts forward a new design scheme for the layout of medical equipment and patient beds in the carriage,which increases from one patient bed to two patient beds in the past.The positions of medical staff and patients cross diagonally,which improves the rescue efficiency.In addition,two pull side doors are set on both sides of the car body,which is more convenient for doctors to go in and out,patients to lift,and medical equipment to be transported.An open back door is set at the rear of the car.There are three large areas of passageways in one car,which greatly improves the efficiency of emergency treatment.And the mathematical evaluation of the satisfaction degree of the interior layout of the car is carried out,and the evaluation result is that the satisfaction degree reaches the standard.(2)The composition and structure of ambulance suspension mechanism are studied.The components are modeled and designed by inventor 3D modeling software.The three-dimensional models of the front and rear suspension are obtained through the whole assembly,and the force is analyzed and calculated,and the chassis motion is analyzed,which meets the design requirements.Through a brief introduction of the working principle,it is conducive to the follow-up research and lays the foundation for the full text.(3)The vehicle suspension system and other subsystems are modeled by Adams,and then the communication devices of the subsystems are connected to generate the vehicle model for simulation.Combining with the programming software,the simulation results are analyzed and the ride comfort index is obtained.Finally,the optimization analysis and iterative simulation of some parameters of the suspension system make the comfort of the ambulance improved significantly.(4)A multifunctional stretcher system is designed,which can be divided into three modes: stretcher,cart and push chair.The new ambulance chair has strong applicability and wide application.It combines the advantages of wheelchair and stretcher,reduces the injury to patients during handling,and makes the handling of patients safer.In this paper,the overall stress analysis of this multi-functional stretcher is carried out,and the finite element treatment of this multi-functional stretcher is carried out,and the results are in line with the strength requirements.In addition,this chapter also carries on the modal analysis of this multi-functional stretcher,and checks the static strength of the rectangular tube and bolt.The analysis results are up to the standard,indicating that the design is reasonable.
