This paper presents a new type of multifunctional bioreactor,which is to provide cell tissue a mechanical environment which is close to the real situation.This bioreactor is based on the concept of fatigue machine,add torsion module to compress and tension module,with new design of both loading device and culturing device by modern CAD technology.Driven by voice coil motor,step motor and a well designed mechanical structure,this machine has excellent controlling performance and no accumulated error,easy to adjust operating height,loading frequency,compressing stroke and torsioning angle.It has different loading modes,with compression or torsion separately,or providing compound load with both torsion and compression.With a delicate culturing device,the height and the limit of loading head is easy to adjust accordingly,it can also provide liquid environment during the loading process,which is closer to biological characteristics and physiological environment.After simple refit,its also able to be used as a tension machine.This machine supplies different mechanical environment for biomechanics research to make related experiments more effective and accurate.
