China has the largest renewable energy generation (27.4%) and consumption (24.6%) in the world. After a decade of development, China has installed the third highest capacity of offshore wind power, following the UK and Germany. However, the share of wind energy generation was 14.8% of the global renewable energy generation and the offshore wind power only accounted for 2.8% of the total wind power capacity in China (as of year 2019) [13]. With the vigorous promotion from the government, the installed capacity of offshore wind power is expected to increase rapidly. Guangdong, the southernmost coastal province in China, for instance, is planning to build 23 offshore wind farms with a total capacity of 66.9 GW by 2030. Offshore wind power is very likely to become a major resource of China's energy supply in the future. |

However, since the mechanical model of the traditional parallel mechanism is be applied to rigid, each of the supporting branches is rigid, therefore, it is necessary to optimize the mechanical model. According to the characteristics of the contact surface, the deformation of each supporting limb is taken into considered instead of the motion caused by the active joint, the active joints of each supporting limb are locked, the reactive force of each active joint can be tested to calculate the external force; the linear stiffness of each supporting limb is considered to find the basic principle of the contact force, thus the a novel mechanical model based on the traditional parallel mechanism is constructed to simulate the human-machine contact force. |
