Mechanical Properties of Tomatoes

According to current situation that domestic tomato picking methods are still relatively single and manual picking is mostly adopted，tomato picking technology was studied.Starting with tomatoes itself，the mechanical analysis of tomatoes was carried out.Tomatoes with vines were used as experimental materials，and precision micro-control electronic universal testing machine was used for shear and compression tests.Statistical software was used to analyze mechanical parameters of tomatoes and vine at each stage，and maximum compressive elastic strength of tomatoes was 0.017 MPa，its modulus of elasticity was 8.33 MPa，and the minimum shear force of tomato vine was 233.05 N.The compressive properties of tomatoes and the parameters of tomato vines under shearing provide some reference for the design of tomato harvesters in the future.
