A crash simulation is a virtual recreation of a destructive crash test of a car or a highway guard rail system using a computer simulation in order to examine the level of safety of the car and its occupants. Crash simulations are used by automakers during computer-aided engineering (CAE) analysis for crashworthiness in the computer-aided design (CAD) process of modelling new cars. During a crash simulation, the kinetic energy, or energy of motion, that a vehicle has before the impact is transformed into deformation energy, mostly by plastic deformation (plasticity) of the car body material (Body in White), at the end of the impact.
Data obtained from a crash simulation indicate the capability of the car body or guard rail structure to protect the vehicle occupants during a collision (and also pedestrians hit by a car) against injury. Important results are the deformations (for example, steering wheel intrusions) of the occupant space (driver, passengers) and the decelerations (for example, head acceleration) felt by them, which must fall below threshold values fixed in legal car safety regulations. To model real crash tests, today’s crash simulations include virtual models of crash test dummies and of passive safety devices (seat belts, airbags, shock absorbing dash boards, etc.). Guide rail tests evaluate vehicle deceleration and rollover potential, as well as penetration of the barrier by vehicles.
It seems like you’re describing a simulation scenario involving ANSYS Workbench Explicit Dynamics, where a dummy without a seatbelt impacts an airbag. ANSYS Explicit Dynamics is a finite element analysis software that is commonly used to simulate transient, dynamic events like impacts, explosions, and crashes. To set up a simulation like the one you’ve described,…
Static structural simulation is a method used to analyze the behavior of a structure under various loads and conditions without considering dynamic effects like acceleration, vibration, or inertia. In the context of a teleferic (also known as a telpher or cable car), a static structural simulation would involve evaluating how the various components of the…

It seems like you’re asking about simulating a scenario in ANSYS Workbench (WB) Explicit Dynamics where a truck with loose cargo experiences deceleration due to braking at 100g (where “g” is the acceleration due to gravity). ANSYS Workbench Explicit Dynamics is a powerful tool for simulating transient dynamic events, including impact, collision, and various mechanical…
