Abstract :
Low back pain was paid more attention, due to cause a decline in the quality of life and great economic costs. There are many risk factors for low back pain using manual material handing, such as poor postures, excessive force and vibration, manual material handing is a high incidence of low back pain industry. This study analyzed the gravity torque, erector spinae muscle strength as well as the extrusion pressure and shear stress acted on the lumbar spine for the worker, with anthropometry and statics theory, the three-dimensional finite element model of lumbar spine was established, lumbar vertebrae and the intervertebral disc stresses were simulated using the finite element method for the worker under lifting posture, which can provide the reference for the quantitative study of the waist muscle loads.
