An oyster transporter is a kind of agricultural machinery that has been successfully developed and manufactured by local industry. Its major function is to carry oyster collecting equipment and oysters. Due to its great adaptability to terrain and resistance to sea water corrosion, it is popular with oyster culturists. Moreover, it undoubtedly reduces the hardship of transport tasks. 　　In recent years, there have been dramatic changes to our oyster aquacultural environment, from the early simple manpower and cattle power carts, to the current vehicles using power engines. However, whether these power engine vehicles are really safe has become a significant issue among local culturists and tourists. 　　In this study, first, the safety parameters such as the braking distance, minimum turning radius, static rolling angle, and slope test are tested with vehicle testing with reference to the article “Performance Test of Agricultural Transporter“. Second, this study uses a computer-aided engineering software named ADAMS as a research tool, to build an oyster transporter’s full car kinematic model and to execute simulation analysis. The relevant vehicle specifications and sizes are in accordance with the actual vehicle measurements and information provided by the oyster transporter factory in Wanggong, Changhua. In the simulation, the maximum speed is limited to 20 km/h. The power of the engine is 19 hp. The vehicle’s loading platform simulates a transporter that is empty or grouped into 600 kg. Moreover, various simulated roads are selected. Therefore, the results can be observed after simulation and compared with field tests. 　　Results from field tests show that the slip rate is within 1% and the minimum turning radius is about 3.25 m to 3.54 m. The vehicle can be parked on 15° slopes without slippage. These tests mean the vehicle has good performance. However, the braking distance of the oyster transporter when empty or with a loading of 547 kg is far more than the standard value determined by the “Performance Test of Agricultural Transporter”. The static rolling angle is about 25 degrees, and the standard value is 35 degrees. However, due to these two data, the safety of the oyster transporter cannot measure up to the standard. 　　Computer simulation results show that the braking distance is mainly affected by the loading. The brake distance is larger when vehicle is loaded. However, the braking distances for an empty vehicle or with a loading of 600 kg are unable to meet the requirement of the regulations in the “Performance Test of Agricultural Transporter”, and the results are about twice the standard value. In addition, the minimum turning radius is in the range of 6.11 m to 6.44 m. Although the results have some deviations with vehicle testing results, the turning performance is still good. For the simulation of the slope field test, the center of mass of the vehicle parked on the slope of 15 degrees is stable and has no slippage. In conclusion, the field tests and computer simulation of the safety performance of the oyster transporter cannot meet the requirements of the regulations of the “Performance Test of Agricultural Transporter”. For this vehicle to be legalized, it should be improved or other regulations should be set up to test the performance of oyster transporters.
