Input data for the creation of a multibody lumbar model

The dataset provides data for the design of a L1-S1 spinal segment model.
The multibody geometry is obtained from a synthetic specimen (Sawbones SKU3440), but the here provided input data can be adapted to any idealised geometry.
The model groups all the passive elements (intervertebral discs, ligaments, facet joints) as a revolute joint with a 3-degree polynomial angle-moment law.
The repository includes:
- Vertebral lamped parameters (i.e., centre of masses, masses, ,direction of principal axis of the body, principal moments of inertia).
- Revolute joints position and the parameters to characterize the vertebral joints in terms of reaction moment.

本数据集旨在为L1-S1脊椎节段模型的设计提供数据。其多体几何形状源自合成样本（Sawbones SKU3440），然而所提供的输入数据可适应于任何理想化的几何形状。模型将所有被动元素（椎间盘、韧带、椎间关节）归类为具有3次多项式角度-力矩定律的转动关节。该仓库包含以下内容：
- 椎体参数（即，质心、质量、身体主轴方向、主惯性矩）。
- 转动关节位置以及表征脊椎关节在反作用力矩方面的参数。
