Changing acceleration and forces are part of the excitement of a roller coaster ride. According to Newton's second law, F = ma, every part of our body must be exposed to a force to accelerate. Since our bodies are not symmetric, the direction of the force matters, and must be accounted for by ride designers. An additional complication is that not all parts of the body accelerate in the same way when the acceleration is changing, i.e. when there is jerk. Softer parts of the body provide varying levels of damping, and different parts of the body have different frequency responses and different resonance frequencies that should be avoided or reduced by the roller coaster designer. This paper discusses the effect of acceleration, jerk, snap and vibration on the experience and safety of roller coaster rides, using authentic data from a dive coaster as an example. (Less)

速度、加速度、急动度、啪啪声和振动:过山车时我们身体中的力

不断变化的加速度和力量是过山车令人兴奋的一部分。根据牛顿第二定律,F = ma,我们身体的每个部分都必须受到一个力才能加速。由于我们的身体不对称,力的方向很重要,必须由骑行设计师考虑。另一个复杂情况是,当加速度发生变化时,即出现急动时,并非身体的所有部分都以相同的方式加速。身体较软的部分提供不同程度的阻尼,身体的不同部分有不同的频率响应和不同的共振频率,过山车设计者应该避免或减少这些。本文讨论了加速度、加加速度、啪嗒声和振动对过山车乘坐体验和安全性的影响,以潜水过山车的真实数据为例。(较少的)
