Occupant Simulation in LS-DYNA®


This two-day class overviews how to set up airbags, seat­belts, seats, and dum­my po­si­tion­ing. We will dis­cuss set­ting up and mod­i­fy­ing oc­cu­pant re­straints in a sled en­vi­ron­ment. Work­shops will be used to il­lus­trate these con­cepts. Up­on com­ple­tion, you will be able to de­sign and de­vel­op your own sled stud­ies for eval­u­at­ing re­straint sys­tems.
